Senior Software Engineer

Department: Engineering

Location: Manhattan

Employment Type: FullTime

Probook is the AI dispatcher 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 proactive communication and around-the-clock workflows, Probook ensures a consistent customer experience without the need for 24/7 manual staffing. We unify these 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 Now

You're joining at the exact inflection point where:

• Product-market fit is proven ($4M ARR in 9 months, 100% word-of-mouth growth)

• 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

• The opportunity is massive ($700B market, still mostly un-automated)

In 12 months, this role will exist, but won't be this role. Right now, you can still define everything.

Benefits

• Competitive salary and meaningful equity

• Full medical, dental, and vision coverage

• Unlimited PTO

• 1K monthly stipend on Ramp

• Comp: 200K - 250K Base
