ABOUT PROBOOK
Probook is the AI Operating System for the home services industry, transforming how plumbing, HVAC, and electrical businesses operate.
Our impact is real. Dispatching the right technician to the right job can mean the difference between a $300 "band-aid" fix and a $20,000 system replacement. By automating previously high-touch workflows around-the-clock, Probook ensures a consistent customer experience without the need for 24/7 live staffing. We unify our customers' processes into a single, scalable platform, giving businesses one place to run their entire dispatch operation.
The Opportunity
This is not a role where you'll work on incremental features—you'll architect and ship the fundamental capabilities that define our platform.
Every feature you build will directly impact ARR. You'll see your work drive customer adoption in real-time, informed by direct customer feedback from our in-person onboarding process.
This is the ground floor of a category-defining company. The systems you build in the next 12 months will scale revenue.
What You'll Do
Build and deploy production AI systems that automate complex decision-making for thousands of service businesses
Ship features at a pace that would be quarterly initiatives at larger companies—expect weekend sprints
Work directly with customers to understand their workflows and translate needs into technical solutions
Integrate state-of-the-art AI frameworks and tools into production systems
Architect scalable backend infrastructure that supports rapid growth
Own critical product features end-to-end, from design through deployment
What We're Looking For
Technical Excellence
Exceptional coding fundamentals—comfortable with quant-level technical problems while leveraging AI coding tools as force multipliers
2-6 years of backend engineering experience, ideally at fast-growing early-stage startups or as a founding engineer
Track record of building impressive systems or products (we actively evaluate for this in interviews)
Ability to master an existing codebase and ship meaningful contributions within 48 hours
Execution & Judgment
Extreme bias for action—you ship fast without sacrificing quality
Strong product sense and customer empathy—you understand what users need and how to deliver value
Architectural judgment—you build robust, scalable systems, not fragile quick fixes
Comfort with ambiguity and rapid context-switching
Why Join Now?
You're joining at the exact inflection point where the technical foundation is still being built — your architecture decisions will matter for years. The team is small enough that you'll shape company culture and technical standards.
In 12 months, this role will exist, but it won't be this role. Right now, you can still define everything.
