Founding AI Engineer @handly - 20VC backed (m/f/d)

You will own AI products end to end, make the core product and technical decisions, and turn messy, real-world workflows into AI that does the work for our partners.

Tasks

AI already runs in production across handly: intelligence on every customer call, automatic payment matching, a daily briefing for every partner. Some of the bigger projects you will contribute to or lead:

• Quote generation. Turn voice notes, photos and documents from customers and architects into a six-figure quote, priced intelligently from the partner's own catalog.
• Measurements. Measure buildings from satellite imagery, drone footage and public building data, without a site visit.
• Back office in natural language. An MCP layer over the whole product, so partners can manage their back office in a chat.
• Email intelligence. Capture intelligence from email threads and attachments, automate communication with clients and suppliers, and aggressive anti-phishing and spam protection.
• Self-improving pipelines. Use every correction, edit and rejection to improve the next output. Evals. Build the evaluation sets and benchmarks that gate every AI feature before it ships.

• Have 4+ years of full-stack engineering experience (exceptions apply for exceptional engineers)
• You have shipped AI features that real users depend on, and continiously evloved them.
• Strong full-stack TypeScript comfortable across backend, web and mobile.
• Experience building evals, benchmarks and self-improving loops that automate research on AI capabilities.
• Creative about capturing data and context (transcripts, photos, documents, voice) to improve AI features.
• Strong prompt engineering: structured outputs, tool use, agents, and good judgment about when an LLM is the wrong tool.
• Comfortable with ambiguity. You lead your projects end to end and want to grow with the company.
• Bonus: you have built your own fully functional AI side project. Send us your best one.

Benefits

• competitive compensation package, €80–110k + 0.4–0.7% equity
• unlimited access to frontier models and our always-on software factory
• as much responsibility as you want, flat hierarchy
• fast loops and direct feedback from the people who use what you build
• minimal meetings: we have plannings and demo Fridays, No stand-ups, we like to maximize our focus time.
• a tight, ambitious team that enjoys building hard things together from the comfort of our office.
• regular team outings: dinners, padel, events and movie nights
• a modern, light-filled office in Berlin-Mitte and great vibes ^^

about the role

This role is for engineers who want to push what AI can do for a real business. As our founding AI engineer, you'll have high agency to hone your skills with AI and solve hard real-world problems that bring delightful experiences to our partners. The biggest opportunity at handly: we run the entire administration of our partners, rather than one vertical of their needs. That gives AI the room to take on large, autonomous tasks end to end, and gives us room to get very creative with what AI can do as we capture more and more channels of communication.

our tech stack

• Full-stack TypeScript: Node.js, Express, Drizzle, Postgres
• Web: React, Vite, React Query, Tailwind, shadcn/ui, Zod
• Mobile: React Native, Expo, EAS, React Query
• AI: Vercel AI SDK, promptfoo, OpenAI and Anthropic models
• Building: we use AI extensively to build, with zero friction adopting the best tools, and we built a custom software factory that takes care of small tasks Infra: AWS, PostHog, Sentry

what may not make you a good fit

• you prefer a remote or hybrid setup
• you want to be told exactly what to do
• you mostly care about the tech, not the outcome for the customer
• you want to work 9-5
