Founding Product Engineer (Frontend)

#### **Overview** Confident AI is building the infrastructure that makes AI trustworthy. 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. We'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. As a founding engineer, the quality bar you set and the interfaces you ship will be the reason engineering teams choose us over the alternatives. #### **What you'll be doing** * Own user-facing features from product decision to design to shipped code. You make the design calls — there are no Figma files waiting for you. * Build data-dense, fast, polished interfaces for traces, evaluation results, and testing workflows — the screens our users live in every day. * Talk to users, understand their workflows, and turn what you learn into product decisions.

You're the engineer in the room closest to the customer. * Work 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. * Architect the frontend to last — the components, state management, and patterns you establish need to hold up as the product and team grow around them. * Set the standard for product quality and user experience that every engineer we hire after you builds to. #### **You should be someone who** * 3+ years building production web applications, ideally at a fast-moving product company or startup. * Deep 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. * A 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. * You understand frontend at scale — rendering performance, state management, data fetching, and architecture that doesn't collapse as the product grows. * Enough backend fluency to move fast — databases, APIs, caching, auth.

You won't be scaling them, but you build against them confidently. * Fluent 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. * You think in user experiences, not components. The question you ask is 'what should this feel like to use,' not 'what props does this take.' * High-agency and comfortable with ambiguity. We're seed-stage — you identify what matters, make a plan, and ship. #### **Your work will** * Be the reason our platform feels like the best product in AI infrastructure, not just the most capable one. * Own the user experiences that engineering teams interact with for hours every day. * Set the product engineering bar the rest of the team builds to as we scale from seed to market leader. #### **By joining us, you will** * Full ownership: you decide what gets built and how it feels, and you ship it yourself. * A seat at the table: direct access to the founding team at the stage where every product decision compounds. * The problem: you'll work on what makes all other AI work trustworthy.

The impact ceiling is massive.
