Fullstack Developer (Senior) (M/W/D)

Building the backbone of European trades together – with AI and voice-first software.

We’re not just building software – we’re on a mission to create space for contractors & tradespeople by equipping them with AI solutions that work the way they do: fast, practical, and voice-first. With Tier 1 Investors from Europe and the US, like Headline and Creandum as well as 20,000+ tradespeople as customer base, we’re scaling across Europe to turn scattered tradespeople into thriving communities. We’re #stoked to shape the future, #together as a team, and #humble in our mission to support the builders of tomorrow.

You’ll collaborate closely with Product Management and Design from early concept to deployment, contributing ideas and delivering high-quality code that helps us realise our product’s potential.

Implement and contribute to the scoping and planning of features and capabilities along the whole software lifecycle - on top of GCP with React in the frontend, serverless express services in the backend - both in TypeScript.

Support and mentor junior engineers within your team, sharing knowledge and best practices.

2+ years of production software engineering experience.

• Experience with TypeScript (Frontend and Backend, ideally React).
• Strong software engineering fundamentals with growing system understanding.
• AI awareness and interest in learning about modern capabilities (real-time voice, Multimodality, LLM Integration).
• English at C1/2 level; German at B2+ level is a plus but not required.

Team spirit matters to us — and we make it visible: with three major team events per year, two casual monthly formats at our Hamburg HQ, and a strong recognition culture where we regularly celebrate both the big and small wins together.

In a flat hierarchy and high-trust environment, you’re empowered to make meaningful decisions and drive real impact.

Learning & Growth : We invest in your personal and professional development through a strong feedback culture, a personal learning budget, and targeted enablement formats. We support every team and individual in applying AI at the next level in their daily work, including getting your own ChatGPT+ license, of course.

Tech & Tooling : You’ll receive a MacBook, premium over-ear headphones, and everything else you need — from hardware to tools — to be effective in your daily doing.

Whether remote, hybrid, or on-site — you work where you’re at your best. Some roles even allow for fully remote setups. Recharge : To ensure the needed rest, we offer 30 vacation days per year (based on a 5-day week) and Dec 24th off. Mobility : You can lease a "JobRad" (Bike) and get a subsidized "Deutschlandticket" or "BahnCard" for public transport to be supported in your commute.

International Environment : We’re becoming more international every month, with team members already in Italy, France, the Netherlands, and Austria — which is why English is our internal company language.
