Senior Fullstack Developer (m/w/d)

Rockstar developers, founded 2015 in Mannheim, additional offices in Stuttgart and Munich. We are a software developer with experience from hundreds of individual projects for enterprise and mid-sized customers.

Short paths, honest feedback, no political games. No hierarchy levels between you and the people who make decisions.

Your Tasks

You will work on customer projects at large companies, embedded in their teams, with full responsibility for your area.

• Fullstack development in enterprise environments
• Co-architecting, not just implementing
• Generating, reviewing, and refactoring code with Claude Code, Copilot, or Cursor
• Code reviews and technical mentoring within the team
• Alignment with Product Owners, UX, and DevOps

Most people come in one to two days a week to one of our offices. Compulsion is not necessary. When you're on-site at the customer's location, you'll only be there for individual appointments every few weeks.

What You Bring

Senior-level. Our customers need people who deliver from day one and work independently.

Tech-Stack:

• Frontend: React or Angular, TypeScript
• Backend: Java/Spring Boot, .NET, Kotlin, or Python
• Cloud: AWS or Azure
• Databases: PostgreSQL, MongoDB, or comparable
• CI/CD, Docker, Git
• Kubernetes, Terraform, Microservices

You don't have to know everything. What's important is that you're comfortable on both sides and can quickly get up to speed with new stacks.

Ai-experience is not a nice addition at our company. Claude Code, Copilot, Cursor: You must be able to work productively with these tools. Not because we want to be hip, but because our customers expect it and we do too. If you hold AI-tools for a hype and prefer to do everything yourself: wrong company.

If you're really strong in the Ai-area, we'll talk without senior level.

What We Offer

• Home office, office, or mix - you decide
• MacBook (except the customer provides their own hardware)
• Varying customers and projects
• The founders are your direct point of contact
• Internal upskilling: We invest in your Ai-skills (EXO 3.0, Agent-Passport, certifications)

Application

CV is sufficient. No cover letter necessary. We'll get back to you within a few days.
