Software Engineer

About the role

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
