About the role
Responsibilities
- Build and maintain frontend components and views for labeling, review, and evaluation workflows with performance, accessibility, and scalability in mind.
- Own outcomes, not tasks: refine scope, suggest trade-offs, propose simpler approaches, and land increments that deliver value fast.
- Partner with Product & Design from discovery to delivery: clarify user jobs, write lightweight RFCs/PRDs, and shape scope and milestones.
- Prototype to de-risk UX; use flags/gradual rollouts; gather feedback from users/support and iterate after releases.
- Raise the bar on FE standards: state management, testing, error boundaries, a11y, i18n, and developer ergonomics.
- Partner with Support to investigate production issues, reduce UX papercuts, and turn learnings into fixes.
- Engage with our open-source community (issues, discussions) to understand real-world needs and improve developer experience.
- Participate in architecture discussions and code reviews; mentor teammates and improve patterns across the codebase.
What you’ll bring
- Senior-level experience shipping production React/TypeScript apps (HTML/CSS mastery; ES6+; a11y).
- Strong product sense: you’ve made scope/trade-off decisions and iterated based on real-world usage and feedback.
- Fluency with modern FE tooling (e.g., Vite/Webpack, Jest/Cypress) and state-management patterns.
- Comfort collaborating with APIs and occasionally touching backend code (Django/REST familiarity is a plus).
- Excellent communication at a Senior IC level—you write clear RFCs/PRDs, give actionable reviews, and present trade-offs well.
Nice to have
- Experience with data/ML tools, OSS, design systems, or performance profiling.
- Familiarity with feature flags/gradual rollouts and qualitative feedback loops (support forums, user sessions).
- Prior work on complex, data-heavy UIs (review tools, multi-step workflows, or IDE-like apps).
