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.
COMPENSATION & BENEFITS
- Equity: Meaningful early-stage equity
- Salary: $200K – $300K
- 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
