About the role
We're looking for a world-class Founding Design Engineer to own product design end-to-end at Blaxel: from the first exploration to production code running in front of real users. You'll design the experience of a new category of cloud computing, then build it yourself, using AI to ship at a speed that wasn't possible even two years ago.
This is a designer-who-ships role, not a handoff role. We need someone who thinks like a mini design founder, treats the product as their own, and closes the full loop: watch how people use Blaxel, design what should change, implement it in production, measure it, repeat.
What you'll do
- Design and ship. Take features from concept to polished UI to merged PR. Your designs land in production and get used by real customers, not archived in a Figma graveyard.
- Use AI as your implementation engine. Pair with AI coding tools to translate your designs into our front-end codebase, accurately and fast, and get them through review like any other engineer.
- Monitor how humans and AI agents actually use the platform. Watch sessions, dig into usage data, and proactively propose how the UX should evolve.
- Close the loop. Ship improvements, measure their impact on activation and platform usage, double down on what works, kill what doesn't.
- Raise the design craft bar everywhere users touch Blaxel: console, onboarding, docs, emails, marketing site.
- Build the foundations: design system, component library, and interaction patterns that scale with the product.
Who you are
- Designer first. Exceptional taste and craft are the bar — taste is the rarest skill in this role and the hardest to learn.
- Obsessive about detail. Spacing, motion, microcopy, empty states, edge cases.
- Technical enough to own a codebase. Solid front-end fundamentals (TypeScript, React, CSS).
- Deeply AI fluent. You use AI as a force multiplier on real design and engineering judgment, not a substitute for it.
- Product-minded. You think in user problems and KPIs, not just screens.
- Mini design founder. Strong ownership, high ambition, comfort with the pace and ambiguity of an early-stage startup.
