Your role in the team
- As a Senior Developer, you actively shape our products and customer relationships and are responsible for important processes such as projects.
- You develop frontend and backend components of TIMEOFFICE further and take responsibility beyond your own code.
- You design architectures, interfaces, and technical concepts, and also implement them.
- You ensure code quality, maintainability, and test coverage throughout the entire development process.
- You actively shape our technological orientation, toolchains, and development processes.
- You work closely and collegially with colleagues from other disciplines and maintain direct communication with our clients.
- You empower colleagues through your expertise, share your knowledge, and support others in their professional development.
Our expectations of you
Education
- You have successfully completed your university studies.
Qualifications
- You are an experienced full-stack developer with a strong all-rounder profile. You work in a structured, self-organized manner with a high quality standard — and at the same time, you know how to make pragmatic progress.
- In the backend, you have extensive hands-on experience with ASP.NET Core Web APIs and Microsoft SQL Server or PostgreSQL with Entity Framework. REST-based architectures, clean API endpoints, and a solid understanding of data models and performance are second nature to you.
- Quality assurance is an integral part of your work: test-driven development, component, integration, and end-to-end testing are good and practiced habits for you.
- You prefer to have boilerplate code handled by AI, such as GitHub Copilot or Claude Code - with a clear focus on code quality, maintainability, and responsibility.
- You communicate openly and empathetically, provide constructive advice, and actively seek help when things get difficult.
- Stagnation is not for you. You are eager for new challenges—in technologies, professional domains, and ways of thinking.
- You are fluent in both German and English, both spoken and written.
- You live in close proximity to Bochum and enjoy being productive in the office together with your colleagues.
- Willingness and enthusiasm to work in direct customer contact.
Experience
- In the frontend, we use Vue/Vuetify and TypeScript. You bring solid experience with modern SPA frameworks — comparable practical experience with React or Angular is also relevant.
- We operate our services cloud-native at Stackit using Kubernetes and Terraform. Ideally, you have hands-on experience with Microsoft Azure and understand cloud infrastructure in general. Not only as a deployment target but, in the sense of DevOps, as part of the architecture that you help design and operate.
- At least 4 years of professional experience as a developer.
What we offer
- On-the-Job Training: No projector, no boring PowerPoints. Instead: Doing it together! Supporting each other.
- Meaningful work: Our solutions impact the daily work of over 300,000 people in social services.
- Working at eye level: We rely on personal responsibility, decentralization, and team autonomy.
- Security: Permanent employment contract from the start.
