Founding Design Engineer

Windmill is building the future of performance.

Your work should speak for itself. Windmill lives in the tools you already use, captures what’s happening, and helps you get the feedback and visibility you deserve without more meetings or managing your manager. Performance reviews shouldn’t feel like homework. Windmill turns the flow of real work into continuous feedback so teams stay aligned automatically. Managers get what they need with clear visibility, faster feedback loops, and fewer blind spots so everyone can focus on doing their best work.

We are NYC based and work together in person. If you are not open to relocating to New York, this is not the right opportunity.

You will be our first Design Engineer. You move fluidly between Figma and production code. You turn vague problems into crisp flows, then into reliable components that ship. You care about taste, speed, and quality in equal measure.

• Own critical journeys end to end. Research, map flows, design in Figma, prototype in code, and ship.

• Design and prototype AI chat experiences that feel fast, useful, and trustworthy.

• Shape our Slack surfaces. Messages, modals, triage flows, and notifications that people rely on daily.

• Improve key funnels. Onboarding, 1:1 prep, feedback routing, performance reviews, and calibration boards.

• Instrument what you ship. Define success metrics, run quick experiments, and iterate with real data.

• Work across the stack as needed to unblock great UI with simple APIs and data shapes.

• 4+ years designing and shipping software used by real customers.

• Experience building B2B SaaS.

• Experience with AI chat systems and conversational UX.

• Mastery of Figma. Strong systems thinking, clean information architecture, responsive layouts, motion.

• Strong front end engineering. React, Type Script, modern CSS, accessibility, testing habits, performance instincts.

• A portfolio and code samples that show your role, decisions, and outcomes.

React, Type Script, Remix, Tailwind, Postgres, Tip Tap, Yjs, Slack platform.

• Small team. High trust. Direct feedback.
