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 isn't a role where you'll optimize existing features-you'll define and ship the product capabilities that unlock our next phase of hypergrowth. The products you build in the next 12 months will serve tens of thousands of users and process hundreds of millions in transactions.
You'll own entire product surfaces end-to-end, set technical and product quality standards for the engineering org, and work directly with leadership to translate business strategy into shipped product.
Every feature you ship will directly impact our ability to capture market share at speed. You'll see your work drive millions in ARR in real-time, validated by direct customer feedback from our in-person onboarding process.
What You'll Do
Product Ownership & Delivery
Own complete product surfaces from conception to production-backend systems, frontend interfaces, AI integrations, and everything in between
Ship production AI products that automate complex workflows for thousands of service businesses
Build features at a pace that would take quarters elsewhere-expect to move at startup velocity while maintaining staff-level quality
Make product and technical decisions that balance user needs, business impact, and technical excellence
Drive multi-month initiatives that unlock major product capabilities and revenue opportunities
Technical Leadership
Design systems and product architectures that scale to 100x current usage
Set the bar for product quality, technical craftsmanship, and user experience across the engineering org
Build robust, scalable systems that enable the team to iterate faster on top of your foundation
Integrate cutting-edge AI frameworks into customer-facing products, staying ahead of the rapidly evolving AI landscape
Make critical technical decisions about architecture, infrastructure, and tooling that impact company trajectory
Strategic Impact
Work directly with customers to understand workflows, identify pain points, and translate needs into shipped product
Partner with leadership to define product strategy and prioritize initiatives that drive ARR growth
Act as a force multiplier-your work should enable multiple engineers to ship better products faster
Mentor engineers and raise the bar through code reviews, product critiques, and technical leadership

Extreme bias for action balanced with product quality-you ship fast without compromising user experience
Leadership & Impact
Track record of setting product quality standards and raising the engineering bar at previous companies
Experience as a product or technical leader who others look to for guidance on what "good" looks like
History of building impressive products that demonstrate exceptional product sense and technical judgment (we actively evaluate for this)
Ability to operate in high-growth, high-ambiguity environments where you define the playbook
Comfort context-switching rapidly across multiple product areas and initiatives
Mission Alignment
