**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
