Senior Applied AI Engineer

Who Are We? Postman is the world’s leading API platform, used by more than 45 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 offices in Boston, New York, Austin, Tokyo, London, and Bangalore - where Postman was founded. Postman is privately held, with funding from Battery Ventures, BOND, Coatue, CRV, Insight Partners, and Nexus Venture Partners. Learn more at postman.com or connect with Postman on X via @getpostman. About the Team: Postman sits at the center of how the world's APIs get built, tested, and consumed. That's an insane dataset. If you've been deep in the agent tooling ecosystem — building with sandboxes, remote execution environments, code generation pipelines — and you've been thinking about what all of this looks like when it's backed by real-world API intelligence at massive scale, this is the role. We're building Agent Mode and the next generation of AI-powered capabilities at Postman. We just released Postman v12, but in the AI world, every day is day zero. This doesn’t mean bolting a chat window onto an existing product. It's rethinking what an API platform becomes in an AI-native, API-first world — where agents don't just assist developers, they become developers. Postman has a unique position to make that real, and we need people who already intuitively understand why. What we need from you: You live in this space. You're not reading about agents from the sidelines — you're building with them, breaking them, and forming opinions about why certain architectures work and others don't. You can talk about the tradeoffs between different sandboxing approaches, how workspace and execution environments shape agent capabilities, and what the actual bottlenecks are in shipping reliable AI features. Your opinions are evidence-backed because you've done the work, either in production or for exploration. You've used AI to 10x yourself. Not theoretically. You have multiple concrete examples — side projects, open source contributions, internal tools, workflow automations — where you used AI tooling to operate at a fundamentally different level of output. If you haven't been experimenting with [almost] every new model, framework, and dev tool that drops, this probably isn't the right fit. You can go from prototype to production. We need people who can evaluate a new paper or technique on Monday, have a working prototype by Wednesday, and ship a production-quality version by the end of the week. The space moves too fast for anything less. You know the tradeoffs — and you're still experimenting. You can speak to the pros and cons of different orchestration frameworks, context management strategies, tool use patterns, and data pipelines. But you also know that what didn't work last month might work tomorrow with a new model or a different approach. What the work looks like: Design and build agent architectures backed by Postman's unique API knowledge graph — collections, environments, schemas, real-world usage patterns across millions of workspaces; Build and manage the data pipelines and experimentation infrastructure that let us ship AI features fast; Move between research and production at speed — prototype new approaches, validate them with real users, and iterate relentlessly; Stay on the bleeding edge of the tooling ecosystem: sandboxes, remote execution, workspace environments, model capabilities, and new paradigms as they emerge; Collaborate across engineering, research, design, and product to figure out what AI-native API development actually looks like — and then build it. Why this matters: Every major AI agent being built today needs to talk to the world through APIs. Postman already has the largest connected API ecosystem on the planet. The opportunity here is to build the intelligence layer that makes AI-native development not just possible but default, in the API-first world. If you've been building agent tooling and wishing you had better data, better distribution, or a bigger surface area to work with, this is it. The basics: 5+ years of engineering experience shipping products at scale; You've gotten deep enough into AI that you want to work on it full time — and you have the projects, contributions, or experiments to prove it; You sense that there’s a massive opportunity in the AI<>API space waiting to be built.; Product instinct — you care about what ships and whether it works for real users, not just whether the architecture is elegant. What Else?: In addition to Postman's pay-on-performance philosophy, and a flexible schedule working with a fun, collaborative team, Postman offers a comprehensive set of benefits, including full medical coverage, flexible PTO, wellness reimbursement, and a monthly lunch stipend. Along with that, our wellness programs will help you stay in the best of your physical and mental health. Our frequent and fascinating team-building events will keep you connected, while our donation-matching program can support the causes you care about. We’re building a long-term company with an inclusive culture where everyone can be the best version of themselves. At Postman we value in person collaboration. We are in office 5 days a week for all roles based out of our hubs in San Francisco Bay Area, Boston, Austin, Tokyo and London. For roles based in Bangalore, employees currently work in the office three days a week and will transition to five days per week by the end of the year. We were thoughtful in our approach which is based on collaboration and grounded in feedback from our workforce, leadership team, and peers. The benefits of our in office model will be shared knowledge, brainstorming sessions, communication, and building trust in-person that cannot be replicated via zoom. Our Values: At Postman, we create with the same curiosity that we see in our users. We value transparency and honest communication about not only successes, but also failures. In our work, we focus on specific goals that add up to a larger vision. Our inclusive work culture ensures that everyone is valued equally as important pieces of our final product. We are dedicated to delivering the best products we can. Equal opportunity: Postman is an Equal Employment Opportunity and Affirmative Action Employer.
