This description is a summary of our understanding of the job description. Click on 'Apply' button to find out more. Role Description A well-funded, early-stage AI product company is building a next-generation browser-native platform for product and design teams. Backed by top-tier investors and led by experienced founders, the team is reinventing how modern tooling runs in the browser. We’re hiring a Staff Frontend Architect to own a browser-native execution environment capable of running dependencies, tooling, and applications entirely inside the browser with strong isolation and performance. This is a runtime / systems engineering role — not a traditional frontend position. You’ll define technical direction and ship production-grade platform infrastructure under real browser constraints. What You’ll Do - Architect a browser-based runtime (Node-like execution, task orchestration, streaming I/O) - Build a high-performance virtual filesystem (in-memory + persistence, caching, module resolution) - Integrate and optimize JS/TS tooling pipelines - Drive performance improvements (cold start, incremental updates, memory usage) - Design secure sandboxing for untrusted code - Lead architectural decisions and mentor engineers Qualifications - 8–12+ years building systems software - 3+ years owning runtime or platform architecture - Deep WebAssembly (WASM) expertise (ABI boundaries, memory models, host interfaces) - Strong browser platform knowledge (Workers, messaging, storage, isolation) - Runtime engineering expertise (event loops, scheduling, concurrency, streaming I/O) - Performance engineering discipline with measurable impact - Experience running untrusted code securely in the browser - Proven ability to architect and ship production systems Ideal Background - Experience building with WebAssembly at a high-growth tech company - Comfortable operating in early-stage, high-ownership environments - Excited to work alongside high-talent-density product and frontend engineers Additional Details - Fully remote within the US or in-person in SF or Bangalore - Competitive equity package - Early-stage company (~20 employees) - Recently raised significant venture funding
