Job Summary
In this role, you actively develop software using Java and Angular as a Senior Fullstack Developer, take responsibility within the team, and clarify technical dependencies in complex system environments.
Job Technologies
Your role in the team
- You actively contribute to development, assume technical responsibility within the team, and ensure that requirements result in clean, maintainable, and reliably deliverable software.
- It's not just about individual features. The customer environment is a large, established system landscape with many applications, interfaces, gateways, API managers, permissions, pipelines, and operational processes.
- You should be eager to understand this environment and build solutions that fit into the bigger picture.
- You do not work far from the client, but actively seek exchange with the relevant teams and specialists on the client side.
- We are looking for someone with a genuine service-oriented mindset: committed, solution-oriented, and with the goal of truly understanding the customer context.
- At the same time, our way of working is changing: some projects are already heavily supported by AI or agents, while others still need to be developed in a traditional and manual manner in the client environment.
- We are looking for people who are comfortable navigating both worlds.
- You work in a small Scrum team with approximately 5-7 people.
- The Product Owner is present and takes charge of the technical management.
- Your role is primarily on the technical side: understanding architecture, code quality, reviews, technical standards, coaching, and pragmatic clarification of dependencies.
- When permissions are missing, interfaces are unclear, firewalls block, or pipelines hang, you stay persistent and bring the right people together.
- You are not a disciplinary manager and not a traditional Scrum Master.
- You lead through technical competence, clarity, moderation, and trust.
- You develop fullstack with Java, Spring Boot, and Angular.
- You, together with the team, ensure maintainable architecture, clean interfaces, reviews, tests, and high code quality.
- You actively familiarize yourself with the existing system landscape: applications, interfaces, gateways, API managers, permissions, pipelines, and operational processes.
- You make technical decisions within the context of the overall architecture and clarify dependencies with other development, architecture, platform, security, or infrastructure teams on the client side.
- You communicate with technical contacts in a committed, transparent, and service-oriented manner.
- You coach colleagues technically, moderate daily stand-ups and technical discussions, and help the team become more technically mature.
- You work closely with the Product Owner and bring in feasibility, risks, and technical dependencies early on.
- You utilize AI-supported development where it is sensible and permissible: refining requirements, formulating prompts, evaluating solution proposals, reviewing code, conducting tests, and integrating results into the existing system landscape.
- In client projects that are still running traditionally, you continue to develop cleanly and hands-on.
- We are looking for senior engineers who know what good software is and use AI as a tool to deliver faster, clearer, and better.
- This includes: considering requirements, sharpening acceptance criteria, precisely managing coding agents, and critically reviewing generated code for architecture, security, quality, testing, and maintainability.
- In short: You don't have to believe that AI can do everything.
- But you should be curious about how good engineers become more effective with AI — while remaining senior enough to ensure quality even without AI.
