Requirements
  • At least 7+ years of experience building frontend or full-stack projects and user experiences.
  • Track record of delivering impactful and engaging user experiences that delight users
  • Deep expertise in building the modern web with JavaScript, HTML, and CSS. You likely have used libraries or frameworks like React or Next.js, but we care much more about the fundamentals than the tech stack.
  • Excellent communication skills. We’re a hybrid team and we’re going to be moving fast together. Good communication is key.
  • Detail oriented. We have to care about the details, and while we don’t expect you to be a designer, you need to care about the product experience that our teams are shipping.
  • Measure twice, cut once. We expect that you are analytical by nature and have experience in delivering features, improvements, and changes that leverage analytics tools (like LaunchDarkly) and experimentation techniques.
  • Customer obsession. As we are a core product with years of muscle memory, we need an engineer who is able and willing to leverage the voice of the customer to expedite decision making, develop conviction, and most importantly delight our user.
  • Based in the San Francisco Bay Area.
Responsibilities
  • Deliver improvements to the core product experience that help us achieve our goals around onboarding and activation
  • Deliver small, measured changes that meaningfully impact end users and successful activation of these users
  • Experiment and identify winners. We have a great foundation of experimentation on the team and you will need to leverage and improve this foundation to ship A/B tested changes that we know have an impact on our goals.
  • Own end-to-end and understand core workflows, driving measurable improvements to user experience particularly focused on first-time user experience (sign-up, onboarding, and beyond)
  • Collaborate and work with end users (developers!) using Postman to understand their core workflows and then use that knowledge to improve our product
  • Broaden your knowledge of the core product and the domain over time, starting with first-time UX but eventually branching out into driving improvement to deeper experiences on the Postman user’s journey
  • Collaborate on team processes to streamline collaboration across US and India team members
Desired Qualifications
  • Experience working with or using full-stack JavaScript / TypeScript
  • Experience working in a React application with state management tools like MobX
  • Experience working on B2B product and/or developer tools

Postman provides an API development platform that helps developers, teams, and organizations design, test, document, and monitor APIs. Its tools cover the full API lifecycle: creating API schemas, sending and automating requests, validating responses, generating documentation, and watching API performance in real time. Work happens in shared workspaces so teams can collaborate on API collections, environments, and tests. Pricing is subscription-based with a free tier to attract individuals and convert them to paid plans, plus premium features and enterprise solutions for larger organizations. Compared to others, Postman combines design, testing, documentation, and monitoring in one platform with strong collaboration and a broad user base, making it easier for teams to manage APIs across different projects. The company’s goal is to simplify building and using APIs, enabling real-time data exchange and scalable API development for organizations of all sizes.

Postman integrates Anthropic's Claude to bring AI-native API development to 40M developers

Postman, the API platform used by over 40 million developers, has integrated Anthropic's Claude model to power its Agent Mode feature. The AI assistant runs on Amazon Bedrock, providing enterprise-grade security and compliance controls. Agent Mode operates within developers' Postman workspaces, using Claude's reasoning capabilities to generate API collections, debug requests, maintain documentation and keep code synchronised. Developers can also access Postman workspaces directly from Anthropic's tools, including Claude Code and Claude.ai. The integration allows developers to search workspaces, generate client code, run API tests and create mock servers without switching tools. Postman, which serves 500,000 organisations including 98% of Fortune 500 companies, reports that users engaging with Agent Mode show consistently higher usage rates.

Dynatrace and Postman integrate AI-powered observability into API workflows with Agent Mode

Dynatrace has expanded its partnership with Postman to integrate AI-powered observability into Postman's Agent Mode, enabling developers to access real-time production data directly within their API workflows. The Dynatrace Model Context Protocol Server is now available in the Postman API Network. The integration allows developers to connect Agent Mode with Dynatrace observability data, surfacing trusted telemetry and correlating API behaviour with live production information. Teams can test APIs, analyse failures and resolve issues using natural language within a single workflow, reducing friction between development and operations. Postman Agent Mode is an AI agent that helps teams build, test and manage APIs using context from existing collections, code and governance standards. The Dynatrace MCP Server is now available via the Postman API Network.
