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 first 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
