Software Engineer

What you'd work on The AI agent loop. Our agents observe device screens, ground actions to UI elements, execute steps, and reflect on whether they worked. It's a capture-ground-execute-reflect cycle and there are a lot of hard problems in making it reliable Distributed workflow orchestration for test execution across pools of devices Device infrastructure for Android and iOS. Emulators, real devices, streaming, automation Our CLI that ties local dev to cloud verification. Build uploads, live device sessions, CI integration OpenTelemetry integration, trace correlation, and the tooling we use to debug executions Real-time execution UX. WebSocket streaming, live device views, graph-based test visualization Building out product surface (CLI, web app, CI integrations) What we're looking for High customer empathy. You think about the user's problem when you're designing a technical solution, not just the technical elegance You enjoy novel problems with real technical and product ambiguity You've built and scaled systems that run in production under real load Practical experience with LLMs, AI infra, or agent-based systems Track record of high ownership and autonomous execution Strong communication Experience that would stand out Mobile build tooling experience (Swift, Kotlin, Flutter) Mobile testing infrastructure, device automation, or mobile platform tooling OpenTelemetry or distributed tracing Workflow orchestration systems CLI or developer tooling Probably not a fit if You want well-scoped tickets You're uncomfortable making architectural decisions without full information You prefer deep specialization in one layer over working across a full stack Why join? Hard technical problems (AI agents, distributed systems, mobile device infrastructure) not CRUD apps Shape technical and product direction from the ground floor Flat hierarchy, high ownership, full autonomy Small, talent-dense founding team in San Francisco Competitive compensation and equity
