Requirements
  • 1+ years of professional development experience or 2+ years of consistent open source contributions
  • Relevant software engineering experience through internships, co-ops, research, open-source work, substantial project work, or early-career full-time roles that demonstrate readiness to contribute in a production environment.
  • Strong software engineering fundamentals and the ability to write, test, debug, and improve production-quality code.
  • Experience with Python or Go, plus willingness to learn whichever language is less familiar for the role.
  • Familiarity with modern development workflows such as version control, code review, testing, and CI/CD.
  • Good judgment when using AI tools for engineering work: you can evaluate outputs, catch incorrect or incomplete solutions, and refine them to fit real system constraints.
  • Comfort taking ownership of scoped problems end-to-end, asking for help when needed, and steadily increasing independence.
  • Strong learning mindset, adaptability, and openness to feedback in a fast-moving platform environment.
  • Clear communication and a collaborative approach to working with teammates and internal customers.
Responsibilities
  • Contribute to the internal developer platform that supports backend development across the company, from local developer workflows to shared services and libraries.
  • Build and improve scoped pieces of developer tooling, including CLI and scaffolding workflows that help engineers create and ship new services safely and consistently.
  • Help maintain and improve CI/CD, linting, and testing workflows in the monorepo, with a focus on reliability, fast feedback, and keeping main healthy.
  • Contribute code to shared Go and Python libraries and services, learning the team’s patterns for safe, maintainable, and consistent usage.
  • Use AI to explore approaches, automate repetitive work where appropriate, and iterate on implementations until they meet real production standards.
  • Debug issues, write tests, and validate behavior in real environments rather than relying only on generated output or assumptions.
  • Improve team documentation, examples, and shared context so both engineers and AI tools can produce better results over time.
Desired Qualifications
  • B.S. degree in computer science or related field
  • Internship, co-op, or early-career experience building internal tools, backend services, or developer productivity tooling.
  • Exposure to monorepo development, CI/CD pipelines, or build systems.
  • Familiarity with Go/Python shared libraries, gRPC/Protobuf APIs, or cloud-based backend systems.
  • Interest in developer experience, self-service platforms, or Golden Path tooling.
  • Curiosity about AI-native developer workflows and excitement about improving how engineers build software with AI.

Abnormal AI launches Attune 1.0 behavioral foundation model to combat AI-driven cyberattacks

Abnormal AI has launched Attune 1.0, a behavioural foundation model for cybersecurity trained on over one billion derived behavioural signals. The model now powers 85% of detections across the Abnormal Behavior Platform. Attune 1.0 uses a unified multimodal architecture to understand normal organisational communication patterns and detect AI-driven attacks. The system identifies approximately 150,000 more attack campaigns weekly than earlier systems and delivers 50% higher precision. It recently identified and blocked a novel Microsoft Teams OAuth phishing campaign two months before public documentation. The company also released Detection 360 Insights for visibility into AI determinations and Custom AI Models in early access. New features for AI Phishing Coach include Phishing Risk Scoring and BEC and VEC Simulations, both now generally available.

A Matter Of Trust: How Ai Is Reshaping Risk Assessment

Financial services institutions have long relied on machine learning for risk management, but the threat landscape has grown exponentially in the age of generative artificial intelligence (AI), according to executives from Capital One, Visa and Alloy. Fraudsters now have access to AI tools, including synthetic identity generation and real-time phishing attacks, they said. But AI is also arming companies to supercharge their defensive capabilities, since trust and security are the foundation of financial transactions. “Trust is the very foundation of commerce,” said Rajat Taneja, president of technology at Visa. “When two unknown parties are transacting, they have to trust that the transaction will occur correctly, the money will be transferred properly, any dispute will be managed, and there’s someone handling fraud and scams.”
