Product engineer (f/m/d) @ handly - 20vc backed

We are building a generational company that will be the operating system for tradespeople in Europe, starting with roofers in Germany.

Roofers do not need more software. They need results: a system that aces everything from sales to measurements to finding new hires so they can focus on their craft. That is what handly does as a business-in-a-box startup.

We test everything inside our own roofing company before launching it to customers. If it does not work in the real world, it does not ship.

We are a hungry and close-knit 10-person team in Berlin backed by top tier investors 20VC, Stride and Base10, €3.75M raised.


Tasks

As Handly’s second Product Engineer, you’ll build the foundation of our platform from scratch and shape our product and engineering culture. You’ll translate messy, real-world workflows into intuitive, AI-integrated software that drives real results.

* Design, build, and iterate on full-stack features using our stack: Frontend: React, Tailwind, Vite, Shadcn/ui, React Query; Backend: Node.js, Express, Drizzle, Postgres; Infra: AWS; Mobile: Flutter
* Integrate AI to solve real business problems, not as a gimmick
* Work closely with early customers to understand the daily pain of roofers and translate it into designed and shipped product features
* Take full ownership from design to deployment and iteration. Define what it means to be a "Product Engineer"
* Crush scrappy work like helping migrate our legacy API to TypeScript


Requirements

* Have 3+ years of full-stack engineering experience (exceptions apply for exceptional engineers)
* Have shipped real products end-to-end, including AI-integrated features, preferably in startups and/or tech companies
* Think in product, not ticket, and care about customer results more than process
* Embrace AI tools (of your choice) as natural extensions of your workflow
* Have strong product and design taste
* Prefer speed and ownership over instruction
* Bonus: Have built your own fully functional (AI-integrated) side projects. Send us your best one!


Benefits

* In-office daily: Berlin-Mitte, modern light-filled workspace with a large balcony
* Velocity: fast loops, direct feedback, no management layers
* Growth: as much responsibility as you can handle
* Team: tight, ambitious group that enjoys building hard things together
* Focus: No stand-ups and only two short meetings per week
* Compensation: €70–100k + competitive equity
