Senior Full Stack Developer (m/f/d)

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.

Your Role

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.

• Professional English and at least B2 German
• Ownership mentality and self-direction

Strong Plus:

• Frontend: Angular 16+
• Infrastructure: AWS (EC2, ECS, RDS, S3), Docker, Redis
• Emerging: Python/FastAPI for AI features

Our Culture

"No bullshit. No politics. No endless meetings."

Work-life balance takes priority over rockstar culture. But when things get critical, everyone shows up.

What We Offer

• Flexible Hours – Ownership-based, not time-tracking
• Real Impact – Your work counts directly
• Team Events – 3-4x per year
• Solid Startup – Bootstrapped, no-bullshit culture
