Job Title: Senior Full-Stack Engineer (Java / Spring Boot / React)

Location: Munich, Germany

We are scaling our engineering team past 6+ developers and need an experienced, autonomous full-stack builder to work alongside our CTO and senior developers on heavy execution. Your balance of rapid prototyping and rigorous architectural discipline (Arc
42, DDD, TDD/BDD) ensures we move fast without sacrificing long-term code quality. In our flat structure, your contributions directly accelerate platform velocity while lifting team craft across the board.

Full-stack feature delivery, clean domain modeling, and hands-on technical contributions across our core platform.

• Design, build, and ship end-to-end full-stack features using Java, Spring Boot, Type Script, and React.
• Collaborate closely with the CTO and senior developers on architecture, system design, and heavy execution.
• Apply rigorous engineering standards including TDD/BDD, Arc
  42 architectural documentation, and Domain-Driven Design.
• Leverage AI-agent pairing workflows and modern CI/CD automation on Azure and Kubernetes to maximize development velocity.
• Coach and support junior engineers through active code reviews, pairing, and shared engineering standards.
• Drive collaborative in-person problem-solving and rapid prototyping from our Munich office.

• ~7+ years of software engineering experience delivering robust, production-grade applications.
• Deep hands-on expertise with Java, Spring Boot, Type Script, and React.
• Strong practitioner of TDD, BDD, and structured domain modeling (Arc
  42/DDD).
• Dedicated software craftsman with personal coding projects or open-source repositories to show.
• Comfortable collaborating closely as a peer and mentoring junior developers in a flat team.
• Based in Munich (or relocating) for regular in-office collaboration.

We balance startup agility with deliberate design: product decisions start with prototyping, and architectural choices are structured around Arc
42, design patterns, and explicit quality constraints rather than gut feelings. While fast-moving and occasionally chaotic, we value thoughtful upfront architecture. Our rhythm combines daily standups and frequent product/feature demos with high individual autonomy, heavily leveraging AI-agent pairing for execution while keeping team collaboration focused on architecture, requirements, and spending time together in person.

• Direct collaboration and high trust alongside the CTO and senior peers in a flat setup.
• A culture that values thoughtful upfront architecture and craft over reckless shortcuts.
• Modern AI-agent pairing workflows that supercharge individual delivery and reduce busywork.
• High autonomy to contribute ideas, introduce new tools, and shape domain patterns.
• Energetic in-person team collaboration in the heart of Munich.

• You are looking for a formal technical lead title or hierarchical management role rather than direct hands-on building.
• You prefer purely remote work and do not want regular face-to-face collaboration in Munich.
• You rely on top-down task management or treat tests, architectural documentation, and peer mentoring as afterthoughts.
