Senior Full-Stack Engineer (Java Spring Boot React)

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 (Arc42 DDD TDD/BDD) ensures we move fast without sacrificing long-term code our flat structure your contributions directly accelerate platform velocity while lifting team craft across the board.

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

• Design build and ship end-to-end full-stack features using Java Spring Boot TypeScript and React.

• Collaborate closely with the CTO and senior developers on architecture system design and heavy execution.

• Apply rigorous engineering standards including TDD/BDD Arc42 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.

• Month 1: Ramp up on our product domain understand the Arc42 architecture and deliver your first production-ready code contributions.

• Month 2-3: Ship end-to-end features tackle complex tasks alongside the CTO and senior peers and introduce constructive process or tooling improvements across the stack.

• By end of Q1: Operate as an autonomous senior contributor and trusted peer in the Munich office who collaborates closely with the team and shares new techniques or practices.

• 7 years of software engineering experience delivering robust production-grade applications.

• Deep hands-on expertise with Java Spring Boot TypeScript and React.

• Strong practitioner of TDD BDD and structured domain modeling (Arc42/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 you bring

• Deep professional experience in full-stack software development with Java Spring Boot and React.

• A strong understanding of building reliable enterprise applications.

• Familiarity with modern software architecture and cloud environments.

We balance startup agility with deliberate design: product decisions start with prototyping and architectural choices are structured around Arc42 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 stand-ups 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 just outside 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.
