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.\nWhat you will do\nFull-stack feature delivery, clean domain modelling, and hands-on technical contributions across our core platform.\n\nDesign, build, and ship end-to-end full-stack features using Java, Spring Boot, TypeScript, and React.\n\nCollaborate closely with the CTO and senior developers on architecture, system design, and heavy execution.\n\nApply rigorous engineering standards including TDD/BDD, Arc42 architectural documentation, and Domain-Driven Design.\n\nLeverage AI-agent pairing workflows and modern CI/CD automation on Azure and Kubernetes to maximize development velocity.\n\nCoach and support junior engineers through active code reviews, pairing, and shared engineering standards.\n\nDrive collaborative in-person problem-solving and rapid prototyping from our Munich office.\n\nYour first 90 days\nMonth 1: Ramp up on our product domain, understand the Arc42 architecture, and deliver your first production-ready code contributions.\n\nMonth 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.\n\nBy 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.\n\nWho this is a fit for\n~7+ years of software engineering experience delivering robust, production-grade applications.\n\nDeep hands-on expertise with Java, Spring Boot, TypeScript, and React.\n\nStrong practitioner of TDD, BDD, and structured domain modeling (Arc42/DDD).\n\nDedicated software craftsman with personal coding projects or open-source repositories to show.\n\nComfortable collaborating closely as a peer and mentoring junior developers in a flat team.\n\nBased in Munich (or relocating) for regular in-office collaboration.What you bring\n\nDeep professional experience in full-stack software development with Java, Spring Boot, and React.\n\nA strong understanding of building reliable enterprise applications.\n\nFamiliarity with modern software architecture and cloud environments.\n\nWhat it's like to work here\nWe 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.\nThe offer\nDirect collaboration and high trust alongside the CTO and senior peers in a flat setup.\n\nA culture that values thoughtful upfront architecture and craft over reckless shortcuts.\n\nModern AI-agent pairing workflows that supercharge individual delivery and reduce busywork.\n\nHigh autonomy to contribute ideas, introduce new tools, and shape domain patterns.\n\nEnergetic in-person team collaboration just outside of Munich.\n\nThis probably isn't for you if...\nYou are looking for a formal technical lead title or hierarchical management role rather than direct hands-on building.\n\nYou prefer purely remote work and do not want regular face-to-face collaboration in Munich.\n\nYou rely on top-down task management or treat tests, architectural documentation, and peer mentoring as afterthoughts.\n\nLet's talk\nIf you are an experienced craftsman who thrives on building fast with modern architecture and AI-assisted tooling in a flat, collaborative team, let's talk.
