Why this role matters 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 quality. In our flat structure, your contributions directly accelerate platform velocity while lifting team craft across the board. What you will do • 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. Your first 90 days • 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. Who this is a fit for • ~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 collaboration.What 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. What it's like to work here 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. The offer • 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. This probably isn't for you if... • 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.
