About the role

Frontend-leaning full-stack role focused on turning frontier model capabilities into fast, polished interfaces for developers and creatives, owning surfaces like Playground and Dashboard, and shipping high-quality web applications from prototype to production.

Responsibilities

  • Shipping high-quality web applications end to end, fast
  • Turning research capabilities into product - first prototype through to production
  • Owning frontend architecture and the practices the rest of the engineering team builds on
  • Setting the visual bar - shared components, interaction detail, and polish
  • Designing for hard interaction problems: long-running generations, iterative editing, large media payloads, real-time inference
  • Driving performance for high-volume media processing and latency that users feel
  • Working with research, infra, growth, and design to decide what's worth building at all

Qualifications

  • A track record of shipping real products that real users depend on, and the war stories to go with it
  • Fluency driving coding agents on non-trivial existing codebases, not just greenfield demos — plus the judgment to review generated code critically, catching the plausible-but-wrong, the insecure, and the unmaintainable
  • A clear view on where agents should not be trusted, and why
  • Visual craft — interfaces look considered, ability to work from a Figma file or from nothing
  • Strong product sense: UX and technical tradeoffs deliberately made and explained to non-developers
  • Excellent debugging instincts across the stack
  • Comfort with ambiguity and pace of an early-stage lab — loose requirements, shifting priorities
  • Nice to have: Experience with React, TypeScript, Next.js
  • Nice to have: Track record of building developer tools or creative applications
  • Nice to have: Interfaces on top of generative models and AI/ML concepts
  • Nice to have: Instrumentation and experimentation experience (analytics, A/B testing, activation funnels)
  • Nice to have: Open-source contributions
