  • Foundational programming ability in one or more languages such as Python, JavaScript/TypeScript, Kotlin, or similar
  • Comfort reading, navigating, and reasoning about code, even in unfamiliar codebases
  • Experience using Git and GitHub or similar version-control workflows, including branches, commits, pull requests, code review, issues, or project tracking
  • Some hands-on experience building, testing, breaking, or securing software. This could include professional experience, internships, security labs, CTFs, bug bounty work, open-source contributions, personal projects, automation scripts, internal tools, or coursework
  • Ability to write clear, maintainable scripts or small programs to solve practical problems, automate manual workflows, analyze data, validate findings, or improve security processes
  • Foundational understanding of common web, API, mobile, cloud, and application security risks, such as OWASP Top 10 issues, authentication and authorization flaws, injection, insecure design, secrets exposure, dependency risks, and data protection concerns
  • Interest in offensive security, such as studying for or completing security certifications, practicing web/API testing, learning exploit development fundamentals, using tools like Burp Suite, or participating in labs and capture-the-flag environments
  • Exposure to vulnerability management concepts, including triage, severity assessment, remediation tracking, false-positive analysis, compensating controls, and risk-based prioritization
  • Ability to reason about risk and tradeoffs, not just identify issues. You can explain what could go wrong, how likely it is, what impact it may have, and what options exist to reduce risk
  • Strong product and engineering empathy. You seek to understand launch goals, technical constraints, user impact, and business priorities before recommending a path forward
  • Clear written and verbal communication skills, including the ability to explain security findings in practical, actionable terms

  • Curiosity, humility, and a growth mindset. You proactively seek feedback, ask good questions, and continue building your technical depth
  • Secure-by-design judgment, including the ability to spot patterns, recommend simple controls, and balance launch velocity with meaningful risk reduction
Responsibilities
  • Partner with product and engineering teams to identify application security risks and help frame them as clear business risks, launch options, and recommended next steps
  • Read application code, configuration, pull requests, logs, and documentation to understand how systems work and where security risks may exist
  • Contribute small code changes, scripts, detections, tests, secure defaults, or automation that improve AppSec workflows and reduce recurring issues
  • Work in GitHub to review code changes, understand engineering context, participate in pull request discussions, track remediation work, and collaborate with engineers
  • Help evaluate vulnerabilities from internal testing, bug bounty reports, security tooling, penetration tests, and other sources; partner with teams to prioritize and remediate issues based on real-world risk
  • Contribute to vulnerability management workflows, including triage, validation, severity assessment, remediation guidance, tracking, and reporting
  • Translate recurring security findings into repeatable mechanisms such as secure coding guidance, checklists, paved paths, lightweight automation, detection logic, reusable review patterns, or developer-facing documentation
  • Work with engineers to understand system designs, data flows, trust boundaries, authentication and authorization models, code paths, and potential abuse cases
  • Communicate security issues clearly to both technical and non-technical audiences, including the risk, tradeoffs, recommended mitigations, and residual risk
  • Build strong relationships across Affirm teams and influence security outcomes without relying on formal authority
  • Help connect AppSec work to customer trust, regulatory/compliance expectations, operational resilience, and business outcomes
  • Continue developing hands-on offensive, defensive, and software engineering skills through practical work, labs, tooling, research, certifications, or contributions to internal security programs

Affirm provides point-of-sale financing (BNPL) for consumers and merchants in e-commerce and retail. At checkout, customers can pay over time through installment plans with transparent pricing and no hidden deferred interest in many cases. It integrates with online stores, mobile apps, and in-store checkout via plugins and APIs, and merchants can use a dashboard to process transactions and access marketing tools. Revenue comes from interest and fees on loans and from merchants who pay to offer Affirm financing, setting it apart from traditional credit cards and other BNPL providers by emphasizing installment-based, predictable repayment.

Affirm climbs to Strong Buy as analysts raise earnings estimates on merchant network expansion

Analysts have become more optimistic on Affirm Holdings, with brokerage recommendations clustering between Strong Buy and Buy. Earnings estimates have been revised higher, leading to a top Zacks Rank of #1 (Strong Buy). Affirm's narrative projects $7.3 billion revenue and $1.2 billion earnings by 2029. This requires 25% yearly revenue growth and an earnings increase of about $900 million from $282.3 million today. Recent developments include an expanding merchant network, with new partnerships including Bed Bath & Beyond brands and Backcountry. However, concentration in key merchant relationships remains a risk factor. The most optimistic analysts assume revenues could reach $9 billion and earnings $1.6 billion by 2029, a more ambitious path than consensus that depends heavily on merchant-funded 0% APR growth.

When new tires can't wait, confidence at checkout matters.

When new tires can't wait, confidence at checkout matters. July 29, 2026 Discount Tire and Tire Rack partnered with Affirm to help customers replace tires with confidence, driving approximately 3x higher conversion and 21% higher average order values on TireRack.com, and 24% year-over-year payment volume growth at Discount Tire Few purchases are as unexpected, or as essential, as new tires. A warning light before a long drive. A puncture that can't be repaired. A failed inspection. Suddenly, what started as an ordinary day becomes a purchase that can easily exceed $1,000. For most drivers, the moment isn't really about whether they can afford new tires. It's about figuring out the smartest way to handle an unexpected expense alongside everything else they have planned. That's the moment Discount Tire and Tire Rack designed for when they partnered with Affirm. "For the everyday driver, tires are often an unexpected purchase they didn't account for," said Steve Fournier Jr., SVP of Omnichannel Operations at Discount Tire. "Providing flexible payment options, like Affirm, is one of the ways we are continuing to invest in making it more hassle free for our customers to get tires when and where they need them." To give customers a clearer path forward, Discount Tire and Tire Rack integrated Affirm across their online and buy online, pick up in store experiences, offering a more predictable way to pay over time for tires, wheels, parts like windshield wipers and accessories, and even installation. Affirm evaluates each purchase before approval, and consumers never pay a penny more than they agree to upfront with no late fees, no hidden fees, and no compounding interest. Customers see the full cost upfront and know exactly when they'll be done. "What sold Tire Rack on Affirm was the transparency and ease of use," said Woody Rogers, SVP of Marketing and Product Information at Tire Rack. "Our customers are practical people in that they want to know exactly what they'll pay and when, with no surprises. Adding a buy now pay later option for tires, and our full breadth of products gave us a financing path that actually matches how an increasing share of our customers think about large automotive expenses." Since partnering with Affirm, checkout conversion among TireRack.com shoppers who choose Affirm has been approximately three times higher than the site average. Those shoppers also spend more, with average order values approximately 21% higher than the site average. At DiscountTire.com, Affirm is now the most popular payment method after traditional credit cards, and payment volume through Affirm has grown approximately 24% year over year. Those results matter because tires rarely wait for a convenient moment. Faced with a major, unplanned expense, plenty of drivers choose Affirm. Not because they have to, but because splitting the cost into clear, predictable payments is simply a smart move. They see exactly what they owe at checkout, exactly when they'll be done, and nothing compounds in the background while they're not looking. Buying tires often isn't optional. But how you pay for it is. And for a growing number of drivers, that choice is Affirm, combined with Discount Tire's brick and mortar convenience and Tire Rack's national reach. Affirm is subject to eligibility. See lending terms at affirm.com/disclosures Methodology: Metrics are based on Affirm internal reporting and partner-provided data. Conversion and average order value metrics reflect Tire Rack performance during the applicable measurement period. Payment volume growth reflects year-over-year results for Discount Tire comparing July 1, 2024-July 1, 2025 with July 1, 2025-July 1, 2026.

Mastercard vs. Affirm: which fintech stock has more room to run?

Mastercard vs. Affirm: which fintech stock has more room to run? 2026.07.22 08:26 (GMT-7) Mastercard Incorporated MA and Affirm Holdings, Inc. AFRM are key players in the rapidly evolving digital payments industry, where demand for seamless, cashless and flexible payment solutions continues to grow. The expansion of e-commerce, digital wallets and installment-based financing is reshaping how consumers and merchants complete transactions. While both companies are benefiting from this shift, they approach the market from different angles. Mastercard operates one of the world's largest global card payment networks, whereas Affirm has built its business around buy now, pay later (BNPL) financing and merchant partnerships. Their overlapping exposure to digital payments, combined with distinct business models and growth strategies, makes them compelling companies to compare. Let's dive deep and closely compare the fundamentals of the two stocks to determine which stock is more attractive now. The case for Mastercard. Mastercard's key growth engine remains the steady expansion of its payments network alongside its fast-growing value-added services business. In the first quarter of 2026, value-added services and solutions' net revenues rose 22% year over year, outpacing the 12% growth in payment network net revenues as demand increased for cybersecurity, authentication, consumer engagement and analytics solutions. Cross-border volumes increased 13% year over year, while switched transactions grew 9%, reflecting healthy transaction activity despite geopolitical challenges. MA is strengthening its presence in the BNPL market through Mastercard One Credential, which allows consumers to access multiple payment options - including debit, credit and installments - through a single credential. The company has expanded the offering through partnerships with SoFi, Fiserv and Blossom, making installment payments more accessible while giving banks and credit unions a flexible payment solution. It beat earnings estimates in each of the past four quarters, with an average surprise of 5.5%. Mastercard Incorporated price, Consensus and EPS surprise. Mastercard is preparing its network for the next generation of digital commerce. Nearly all Mastercards are now enabled for Mastercard Agent Pay, while Verifiable Intent adds an extra layer of security for AI-driven transactions. The company is also expanding partnerships with OpenAI and Crossmint to support secure autonomous payments, positioning itself at the center of emerging agentic commerce. Mastercard continues to integrate stablecoins across its ecosystem, including Mastercard Move and settlement capabilities, while the planned acquisition of BVNK is expected to strengthen its ability to send, receive, convert and hold stablecoins. This infrastructure can unlock new use cases in cross-border B2B payments, remittances and payouts without disrupting its core card business. MA has continued broadening its digital payments ecosystem through new partnerships. The company recently introduced Open USD alongside leading financial and technology partners to simplify stablecoin adoption, expanded Mastercard Move's cross-border payment capabilities and rolled out additional AI-powered fraud prevention and cyber intelligence solutions. These initiatives complement its strategy of generating growth from both payment volumes and higher-value services. However, the upside was partly offset by escalating operating expenses and higher rebates and incentives. In the first quarter of 2026, adjusted operating expenses rose 11% year over year. Its long-term debt-to-capital of 71.9% is higher than the industry's average of 39.4% and AFRM's average of 70.5%. The case for Affirm. Affirm continues to strengthen its position in the buy now, pay later (BNPL) market by expanding its merchant network and increasing consumer engagement. In the third quarter of fiscal 2026, gross merchandise volume (GMV) climbed 35% year over year to $11.6 billion, while revenues rose 33% to $1 billion, reflecting healthy consumer demand and higher merchant adoption. Total transactions grew 45% year over year in the third quarter of fiscal 2026. The company's ecosystem is also benefiting from growing adoption of the Affirm Card, which combines debit functionality with flexible installment payment options. Unlike traditional BNPL products used only at checkout, the card enables consumers to access installment financing for everyday purchases, helping drive repeat usage and strengthening customer relationships beyond one-time transactions. AFRM's active consumers increased 22% year over year to 26.8 million, while transactions per active consumer improved 20% to 6.7, indicating that customers are using Affirm's platform more frequently. Affirm is broadening its reach through strategic merchant partnerships and platform integrations. The company recently added Bed Bath & Beyond, Overstock and buybuy BABY to its merchant network, extending financing options across major retail brands. It also continues to deepen relationships with large commerce platforms and payment providers, supporting sustained growth in merchant acceptance and payment volume. As of March 31, 2026, Affirm served approximately 515,000 active merchants, up 43.8% year over year, reflecting broad adoption across online and in-store commerce. AFRM is also investing in technology and product innovation to diversify its business beyond traditional BNPL services. The company is leveraging artificial intelligence to improve customer experiences and operational efficiency while exploring opportunities in new markets and financial products. These initiatives, combined with its expanding merchant ecosystem and growing consumer base, are expected to support its long-term growth trajectory. It beat earnings estimates in each of the past four quarters with an average surprise of 74.9%. Affirm Holdings, Inc. price, Consensus and EPS surprise. However, the expansion is accompanied by rising cost pressures, with total operating expenses increasing 20.1% year over year in the third quarter of fiscal 2026, primarily due to increased provisions for credit losses, losses on loan purchase commitments, funding costs, technology and data analytics expenses and elevated processing and servicing expenses. How do estimates compare for MA & AFRM? Estimates are in favor of AFRM at this stage. The Zacks Consensus Estimate expects MA's 2026 sales and earnings per share (EPS) to grow 12.9% and 15.4% year over year, respectively. For 2027, EPS is expected to climb another 15.6%. Meanwhile, AFRM's fiscal 2026 sales and EPS estimates point to 30.6% and 720% year-over-year increases, respectively, followed by a 39.2% EPS rise in fiscal 2027. Price performance comparison. Over the past six months, Affirm outperformed Mastercard. Meanwhile, the S&P 500 has increased 7.4% during this time. Price performance - MA, AFRM & S&P 500. Image Source: Zacks Investment Research Valuation: MA vs. AFRM. On a price-to-sales basis, MA sits at 12.02X forward revenues, significantly above Affirm's multiple of 4.62X. AFRM's cheaper P/S multiple leaves room for significant growth as business expansion accelerates. Image Source: Zacks Investment Research Price target. Mastercard currently trades below its average analyst price target of $641.64, implying a 17.2% potential upside from current levels. Meanwhile, Affirm currently trades below its average analyst price target of $91.48, implying an attractive 21.5% potential upside from current levels. Conclusion. Both Mastercard and Affirm are well-positioned to benefit from the continued shift toward digital payments, but their growth profiles differ significantly. While MA offers stability through its diversified payments ecosystem, AFRM stands out with faster revenue growth, stronger earnings momentum, a lower valuation and greater upside potential. For investors seeking rapid future gains rather than stability, Affirm has the edge at the moment. While AFRM currently carries a Zacks Rank #2 (Buy), MA has a Zacks Rank #3 (Hold).
