Job description
04 Leipzig, Deutschland Veröffentlicht: Gestern IT / Telekommunikation Vollzeit
We're a B2B SaaS startup in Leipzig connecting packaging buyers with suppliers through an intelligent procurement platform. We've achieved product-market fit with paying customers and are now scaling product and engineering team.
As the third engineer, you're "the first hire that shapes how we grow". You'll work across the entire platform - from the Java/Angular backend to AI document processing in Python. You'll build CI/CD pipelines and strengthen our engineering foundations.
This role means ownership and decision-making - not just working through tickets.
Activities
Your Responsibilities
- Development across the Java/Angular stack (backend and frontend)
- Python/FastAPI for AI document processing
- Build and improve CI/CD pipelines and infrastructure
- Increase test coverage and engineering robustness
- Shape architecture and technical decisions
Strong Plus:
- Experience with AI coding tools
- Modern AI/LLM experience
- Python skills
- AWS experience
- Startup or small team background
Our Tech Stack
- Backend: Java 17, Dropwizard, PostgreSQL
- Frontend: Angular 16+
- Infrastructure: AWS (EC2, ECS, RDS, S3), Docker, Redis
- Emerging: Python/FastAPI for AI features
Requirements
- Team player mindset - We win and lose as a team. No rockstars, no egos. Just people who genuinely enjoy working together.
Benefits & conditions
- Transparency & pragmatism - Say what you mean, focus on what matters. No politics, no meetings for the sake of meetings.
- Problem solvers, not problem creators - We're looking for people who simplify things and get stuff done - not people who overcomplicate matters and make the pile of work grow ever higher.
- Shared ownership - We value work-life balance, but when things get critical, everyone shows up. Reliability matters.
- Substance over show - We care about real results, not self-promotion or "10x developer" posturing.
- Passion for the mission - We actually enjoy coming to work, and we're looking for someone who shares our vision and brings that same energy.
Team
Small tech team at a B2B SaaS company with proven product-market fit - now scaling. You'll work directly with our CTO, Senior Developer and CPO. No bureaucracy, short decision paths, real ownership. We're growing the team, so you'll have a genuine say in how things evolve.
