Senior Software Engineer - Infrastructure

Who we are

• Probook is the AI operating system for home services. We started with dispatch, the decision that determines how a $750B industry makes its money, and have since built across the rest of the front office. Our customers do $10M to $100M a year in revenue and run their operations on us.
• Dispatch was the first step. The harder problems are ahead of us.

Our team

2x IMO medalists, 3x ICPC World Finalists and coaches, a Columbia professor, former founders, MIT, Waterloo, GT, and engineers from Citadel Securities, Stripe, Palantir, Two Sigma, and Meta.

What we want you to own

• Product infrastructure.
• 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.
• Agent infrastructure.
• 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.

Who this is for

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.
