Engineering teams spend hours a day inside our platform looking at traces, evals, and test results - the frontend isn't a layer on top of the product. It is the product.\nWe're hiring a Founding Product Engineer to own that product end-to-end. You'll talk to users, decide what gets built, design the UI yourself, and ship it - from the component layer down to the API routes that power it. No PM writing specs, no designer handing you mocks.\nAs a founding engineer, the quality bar you set and the interfaces you ship will be the reason engineering teams choose us over the alternatives.\nWhat you'll be doing\nOwn user-facing features from product decision to design to shipped code. You make the design calls - there are no Figma files waiting for you.\nBuild data-dense, fast, polished interfaces for traces, evaluation results, and testing workflows - the screens our users live in every day.\nTalk to users, understand their workflows, and turn what you learn into product decisions. You're the engineer in the room closest to the customer.\nWork across the stack. Most of your time is in the frontend, but you'll write the API routes, queries, and server logic your features need without waiting on anyone.\nArchitect the frontend to last - the components, state management, and patterns you establish need to hold up as the product and team grow around them.\nSet the standard for product quality and user experience that every engineer we hire after you builds to.\nYou should be someone who\n3+ years building production web applications, ideally at a fast-moving product company or startup.\nDeep proficiency with React, Next.js, TypeScript, and CSS. You don't reach for a UI library because you can't write the styles yourself - you reach for one when it's the right call.\nA genuine eye for design. You notice when spacing is off by 2px, you have opinions on motion and hierarchy, and you can take a feature from idea to polished UI without a designer.\nYou understand frontend at scale - rendering performance, state management, data fetching, and architecture that doesn't collapse as the product grows.\nEnough backend fluency to move fast - databases, APIs, caching, auth. You won't be scaling them, but you build against them confidently.\nFluent with AI coding tools like Claude Code and Cursor as part of your daily workflow. At our size, every engineer operates at a multiplied level.\nYou think in user experiences, not components. The question you ask is 'what should this feel like to use,' not 'what props does this take.'\nHigh-agency and comfortable with ambiguity. We're seed-stage - you identify what matters, make a plan, and ship.\nYour work will\nBe the reason our platform feels like the best product in AI infrastructure, not just the most capable one.\nOwn the user experiences that engineering teams interact with for hours every day.\nSet the product engineering bar the rest of the team builds to as we scale from seed to market leader.\nBy joining us, you will\nFull ownership: you decide what gets built and how it feels, and you ship it yourself.\nA seat at the table: direct access to the founding team at the stage where every product decision compounds.\nThe problem: you'll work on what makes all other AI work trustworthy. The impact ceiling is massive.\nThe entire process is usually fully remote and all communication happens over email or via video chat in Google Meet. We know that you may be interviewing elsewhere as well so are respectful of your time and will get back no later than 2 days of each step along the process.\nThe entire process has 4 steps and takes around 1.5 weeks in total:\nInitial 15-30 minute phone screening interview.\nOne 30-45 minute technical interview.\nOne week fully-paid work trial.\nFull-time offer.\nNo hires will be made without a work trial. You'll be working with the founders directly throughout the entire process.
