Job Details

Senior-level experience shipping production full-stack features (React/TypeScript + Python/Django + SQL).
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.
Backend depth: REST API design, relational modeling, migrations, performance tuning, and background job patterns.
Excellent communication at a Senior IC level—you write clear RFCs/PRDs, give actionable reviews, and present trade-offs well.

Build full-stack features: React/TypeScript on the client; Django/REST services, data models, and background jobs on the server.
Own outcomes, not tasks: refine scope, suggest trade-offs, propose simpler approaches, and land increments that deliver value fast.
Design clean API contracts and evolve schemas/migrations; improve performance and reliability (query tuning, caching, job orchestration).
Partner with Product & Design from discovery to delivery: clarify user jobs, write lightweight RFCs/PRDs, and shape scope and milestones.
Keep UIs accessible and responsive; add solid error-handling and failure-mode UX.
Raise engineering standards: testing strategy, code quality, observability hooks, resilience patterns.
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.
