Job description

About Probook

Probook is building AI infrastructure for the $700 billion home services industry.

We've scaled from 0 to $10M ARR in under 18 months while remaining cash-flow positive from day one. Our ambition isn't modest—we're building the fastest-growing, most talent-dense startup in NYC and the dominant platform in home services.

The Opportunity

We're hiring a Staff Product Engineer to own the product experiences that will scale us from $10M to $100M+ ARR.

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.

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
  

What We're Looking For

Technical Excellence

• 7+ years of product engineering experience shipping customer-facing products end-to-end

• Deep expertise in building complete product experiences—you're comfortable across the stack and can ship features independently

• Track record of building 0 Polizei products that reached meaningful scale, ideally as a founding or early engineer

• Expert-level coding fundamentals with sophisticated judgment about technical trade-offs and where to invest quality

• Battle-tested experience shipping production AI/ML products that customers depend on

• Strong product instincts—you know how to build features that users actually want and that drive business outcomes
