Your mission
You don't just want to build features - you want to build AI products that solve real problems for real users, with React as your primary tool and Python as a solid backend foundation? Then you're in the right place.
We're a family-owned scale-up headquartered in Munich with over 400 employees across five locations in Europe. Our platform gives thousands of people worldwide a flexible, self-determined way to work - and we're still growing.
AI is not a trend for us: we've been running AI features in production long before the hype started - backed by a strong research team in NLP, Speech and Computer Vision. Now we're building a dedicated AI Unit that owns AI products end-to-end - like a startup inside a scale-up.
We're looking for you: a (Senior) Full Stack Engineer (m/f/d) with a strong React foundation who lives end-to-end ownership and builds AI products that users can rely on every single day.
Work hybrid from our offices in Munich, Berlin or Sofia (Bulgaria).
* __React-first UI development:__ You build complex, high-performance frontends with React Router 7+, TypeScript and deliberate component design - for voice interfaces, coaching tools and AI QA dashboards used by agents on a daily basis.
* __AI integration from UI to service layer:__ You wire LLM APIs, voice models and NLP services into production-ready systems - and build the Python backends (FastAPI/Django) that make those integrations run reliably.
* __End-to-end ownership:__ You take systems through their full lifecycle - from MVP and pilot to high-scale production systems processing thousands of calls per day. Performance, stability and monitoring (Prometheus/Grafana) are always on your radar.
* __Solve real problems:__ Working closely with Product Managers, AI Engineers and other engineering teams, you translate business requirements into technical solutions that actually ship - pragmatic, impactful and user-focused. Good UX starts in the code.
* __Creative freedom:__ You bring your own ideas to architecture decisions, component design and development processes. Your perspective shapes how our AI products look and work.
Your skillset
* __React expertise (must-have):__ You bring several years of hands-on experience with React and TypeScript - component architecture, state management, performance optimization and testing are part of your daily work, not just theory. You use React Router 7+ and modern patterns (Hooks, Composition) as a matter of course.
* __Full stack breadth:__ You build solid Python backends with FastAPI or Django and are comfortable with BFF patterns, REST APIs and database integrations (PostgreSQL, MongoDB). Our stack: Python 3.11, React Router 7 with TypeScript, type hints and pre-commit hooks for clean code.
* __AI integration experience:__ You've shipped LLM APIs, voice services or NLP models into production systems - not just side projects. You know how to embed AI outputs into UIs that actually feel good to use.
* __Tooling & infrastructure:__ Docker, Git and CI/CD pipelines are part of your everyday workflow. You're comfortable on Linux systems and ensure stable development and deployment processes. "You build it, you run it" - Prometheus and Grafana are familiar territory.
* __Ownership & pace:__ You turn rough requirements into concrete tasks, work proactively with cross-functional teams, and know when clean code matters and when shipping fast matters more.
Your winning deal
* __Your Benefits:__ 30 vacation days, monthly lunch allowance (€69), "Givve" card topped up with €50/month, discounts via Corporate Benefits, JobRad leasing, pension scheme support, and legendary team/company events.
* __Your Workplace:__ A modern, dog-friendly office and flexible hybrid working model. Plus: 2 weeks of "Workation" per year within the EU (for EU passport holders).
* __Your Footprint:__ A key role in a profitable company where you’ll have the freedom and trust to shape our journey and help define the future of work.
* Our Culture: We offer an open, authentic, and supportive team culture. We value bold decisions, fresh thinking, and humor – and we’re excited to take the next steps with you.
* __Your Opportunity:__ From day one, you'll have the chance to take ownership, drive innovation, and grow together with a team of experts – shaping both the company and your career.
