Job summary

Probook is the AI operating system for home services, driving the real-time decision layer for dispatch and front office. We seek engineers who own infrastructure from design to production, with a startup mindset to ship robust systems quickly.

Join us to build product, agent, and developer-platform infrastructure, ensuring reliability and observability while controlling costs. You’ll work with world-class engineers and customers, with meaningful equity and strong health benefits.

Qualifications

• 3-6 years of engineering experience with ownership of infrastructure you built.
• Strong fundamentals across distributed systems, cloud infrastructure, networking, CI/CD, and observability.
• Real software engineering; own complex systems end-to-end.

Responsibilities

• Own and operate the infrastructure behind real-time decision systems.
• Build sandboxes, evaluation infra, and agent compute environments.
• Develop the developer platform: CI/CD, deployment, and tooling.
• Improve reliability, observability, monitoring, and incident response.
• Manage cloud costs and capacity planning as the product scales.
• Collaborate with product engineers and customers directly.

Job description

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.
• Equity: Meaningful early-stage equity
• Health: Comprehensive medical, dental, and vision
• Perks: $500 monthly Ramp card for commuting, meals, gym, etc. (plus $25 in nightly meal delivery credit) and really good office snacks
• Access: Direct access to world-class investors and advisors
