Job summary

Probook is the AI operating system for home services, delivering real‑time decision systems and a scalable developer platform. You’ll own infrastructure from durable execution to workflow orchestration, writing code that ships quickly and reliably in production.

We seek engineers with 3–6 years of experience who can start from scratch, tackle distributed systems, and drive cost and scale as we grow. Equity, a competitive salary range, comprehensive health benefits, and direct access to top

Qualifications

• 3–6 years of engineering experience with meaningful ownership of infrastructure you built rather than inherited.
• Zero-to-one experience. You've built infrastructure from scratch at a startup, or stood up new systems on a team inside a larger company.
• Strong infrastructure fundamentals across distributed systems, cloud infrastructure, networking, CI/CD, and observability.
• Real software engineering. Infrastructure at Probook means writing code and owning complex systems end to end, from design through production.
• Breadth over depth. You'd rather build new systems than operate mature ones, and you move up the stack when that's where the problem is.
• Judgment. You know when a system deserves careful architecture and when it deserves to be finished this week.

Responsibilities

• Build and operate the infrastructure behind our real-time decision systems — durable execution, workflow orchestration, reliability, and performance for products customers run their business on.
• Build the sandboxes, evaluation infrastructure, and harnesses our engineers use to develop and ship agent workflows, including the compute environments agents execute in.
• The developer platform. CI/CD, deployment, local development, and internal tooling — the abstractions that let the team ship in days rather than quarters.
• Reliability and observability. Instrumentation, monitoring, incident response, and debugging tooling for systems whose failure modes are often probabilistic rather than deterministic.
• Cost and scale. Cloud and inference costs as the product footprint grows, and capacity and architecture decisions made before they become bottlenecks.
• Partner across engineering. Work directly with the product engineers building on your infrastructure, and with the customers affected by it.
