Senior Java Software Engineer
This is what your daily work looks like
- At the core: In an agile Scrum team, you develop sophisticated, architecture-compliant solution variants according to CSS and internal team specifications.
- You programme sustainable solutions and ensure high software quality through quality assurance, automated tests, and product regression.
- In your work, you use modern technologies and architectures such as Java/Jakarta, event- and workflow-based architectures, Docker, and Kubernetes.
- You apply modern software engineering practices, including AI-Driven Development, Clean Code, Clean Architecture, Test-Driven Development, Behaviour-Driven Development, and Domain-Driven Design.
- Following the principle "You build it, you run it," you accompany the software as a member of the DevOps team from conception to operation.
- You work closely with the business and other development teams, contribute your ideas and experience, and share your knowledge. At the same time, you continuously expand your expertise around EFAS.
This is what you bring with you
You have several years of experience in software development with the Java/JEE stack as well as with Kubernetes and DevOps. Experience in web development, with Angular, and in the health insurance sector is a plus.
- You enjoy tackling complex issues in your work and develop high-quality, sustainable, and maintainable code.
- You use AI-supported development tools and AI agents such as GitHub Copilot purposefully in your daily development routine. You critically review their results and take responsibility for quality, security, and technical correctness.
- In your daily work, you act independently, creatively, and solution-oriented and actively contribute to the agile team.
- You are willing to familiarise yourself with new technical topics around EFAS.
- You communicate openly, share your knowledge, and enjoy working with different stakeholders. You bring a Lean-Agile mindset and are open to learning collaboration in a SAFe environment.
Good reasons - typical CSS
- Work flexibly: Your team often works from home or on the go. Thanks to a laptop with an integrated SIM card and other technical possibilities, this is no problem.
- Keep learning: Stay up to date thanks to our Software Engineering Academy, Innovation Days, and attending external conferences.
- Enjoy your wallet: Benefits such as bonuses, Reka, discounted health insurance premiums, and more, which can quickly add up to several thousand per year.
- Choose your holiday model: 5 or 6 weeks of holiday? Your decision. Accordingly, you work 41 or 42 hours per week.
- Take a break: Home renovation, world travel, or learning languages – what is your dream? Celebrate your 10-year anniversary with a two-month sabbatical.
- Enjoy your family life: Take time for your offspring: 3 weeks for fathers, up to 20 weeks for mothers. In addition, there are generous child and education allowances.
