Backend Software Engineer, API Client (Node.js and/or Golang)

Who Are We?

Postman is the world’s leading API platform, used by more than 40 million developers and 500,000 organizations, including 98% of the Fortune 500. Postman is helping developers and professionals across the globe build the API-first world by simplifying each step of the API lifecycle and streamlining collaboration—enabling users to create better APIs, faster.

The company is headquartered in San Francisco and has an office in Bangalore, where it was founded. Postman is privately held, with funding from Battery Ventures, BOND, Coatue, CRV, Insight Partners, and Nexus Venture Partners.

P.S: We highly recommend reading The "API-First World" graphic novel to understand the bigger picture and our vision at Postman.

The Opportunity

Please note: we at Postman try to keep levels flat so that engineering is a meritocracy. So if you see yourself or call yourself a “Senior Engineer,” an “Engineer,” or something in between, please consider applying and we’ll calibrate on level, experience, and team needs in the interview panel!

The API client is the core beating heart of the Postman product experience. It is what many users perceive as the entirety of Postman (although there is so much more!), and we have ambitious goals in 2024 and beyond to delight developers and simplify this central product experience. As part of this, we're looking for a Backend Engineer to bring depth, craft, and resilience to the infrastructure that underpins it all.

We have three major thematic goals we’re pursuing on the API Client team and you’ll be a key contributor in realizing them:

• Delight the Developer. The developer is central to Postman’s mission. We intend to meet them where they are—faster feedback cycles, GitHub-first thinking, and intuitive features that anticipate their needs and respect their time.
• Simplify request sending and debugging. Postman’s power is immense—but we must distill that power into a smooth, low-friction experience that makes common tasks effortless and advanced workflows discoverable when needed.
• Build the multi-protocol future. Postman isn’t just about REST anymore. We’re investing deeply in modern protocols—GraphQL, gRPC, WebSockets—and tying them together into a seamless, end-to-end experience.

Behind every fast, reliable API call made in Postman is a constellation of backend systems doing the heavy lifting—executing code, orchestrating local runtimes, syncing data, collecting telemetry, and providing rock-solid observability. That’s where you come in.

What You’ll Do

As a Backend Engineer on the API Client team, you’ll do more than write backend code—you’ll own critical infrastructure that directly impacts millions of developers. You’ll partner with engineers across the stack to identify bottlenecks, build scalable systems, and proactively improve our platform’s performance, reliability, and observability.

You’ll thrive here if you’re a generalist at heart with deep backend expertise—someone who isn’t satisfied with "it works" and instead asks "how does it scale," "how do we measure it," and "how do we make it better for the next 10 million users."

Your responsibilities will include:

• Leading the design and evolution of backend systems that power request sending, local runtimes, and telemetry for the API client.
• Owning our observability pipelines—building tools and instrumentation that help us identify, diagnose, and resolve issues affecting thousands of developers in real time.
• Migrating services to Kubernetes-based infrastructure with a focus on performance, security, and cost efficiency.
• Defining new baselines for clean, fault-tolerant, and maintainable services that scale across millions of users.
• Collaborating with frontend engineers, designers, and PMs to shape API client features from end to end—because we don’t believe in silos. You're not a “backend engineer.” You're an API client engineer with deep backend expertise.

About You

• Have 5+ years of backend engineering experience, with a strong foundation in Node.js and/or Golang.
• Have deep expertise and experience in Kubernetes, Docker, Grafana, and modern CI/CD infrastructure
• Have built, maintained, and scaled distributed systems in production environments.
• Think in systems: you’re passionate about observability, reliability, performance, and ensuring that these are understood by everyone on the team as it relates to our backend systems.
• Can navigate legacy codebases and leave them better than you found them.
• Communicate clearly and effect
