Job Summary
In this role, you will develop robust backend systems and APIs, improve existing codebases, and make technical decisions to create sustainable software solutions in diverse client projects.
Job Technologies
Your role in the team
- Do you want to influence code, architecture, and collaboration rather than just working through tickets?
- We are a team of around 30 members and develop customized software solutions for demanding client projects.
- Instead of corporate structures and lengthy approval chains, you can expect short paths, direct decisions, and genuine proximity to projects, clients, and technology.
- For various client projects, we develop backend systems and APIs - from mobile apps and web applications to platforms that connect multiple systems.
- This often involves clean integrations, stable data flows, and long-term maintainable architectures that evolve over the years.
- We deliberately avoid traditional titles such as 'Senior' or 'Junior'.
- Responsibility for us does not arise from a title, but from your contribution: your technical understanding, the quality of your solutions, your collaboration within the team, and your impact on the project.
- Roles develop from responsibility and experience in daily project work — not from hierarchies.
- Our projects are diverse and rarely trivial: different clients and industries, systems that grow and evolve over years, technical decisions balancing quality, time, and pragmatism.
- Much of it already works very well.
- At the same time, there are always areas that we want to improve together - technically, organizationally, and in our collaboration.
- If you enjoy thinking along, taking responsibility, and creating sustainable solutions, you are exactly right with us.
- You are not only working on individual features but also on the further development of the systems themselves: development and enhancement of backend systems and APIs, design and implementation of robust interfaces and data models, structuring and improving existing codebases, active participation in code reviews as a technical exchange, meetings and classification of technical decisions within the project, contribution to the advancement of quality, maintainability, and team collaboration, development of automated tests, and sustainable development standards.
- You don't have to rebuild everything – but you should be able to make things visibly better.

Our expectations of you
Education
- You have a degree in Computer Science or a comparable qualification.
Qualifications
- For our projects, we are looking for team members who think beyond individual tasks, take responsibility, and want to help shape sustainable software solutions.
- You make informed decisions — even when not all the information is available.
- You work in a structured, meticulous, and pragmatic manner.
- You question existing solutions and seek sustainable improvements.
- You value functional, type-safe, and maintainable solutions in software development.
- You have a good sense of how technical decisions impact long-term maintainability, extensibility, and team productivity.
- You are interested in developing your professional skills and learning new things.
- Finally: You enjoy software development — understanding complex contexts, solving problems, and collaboratively developing good solutions.
Experience
- You have a solid technical foundation and practical experience in backend development.

What we offer
- We have a clear commitment to quality and continuously improve our way of working.
- Technically, we rely on the following technologies and standards: PostgreSQL, modern API development with REST, GraphQL, and OpenAPI, as well as automated testing as an integral part of development.
- We develop backend systems and APIs that are used in various client products and must remain sustainable in the long term - ranging from classic REST and GraphQL interfaces to more complex data and integration systems.
- Depending on the project, we operate in a Scala environment with Play Framework, Apache Pekko, Slick, and Cats or in a .NET environment with .NET 4.8/Core, Entity Framework (Core), xUnit, and Testcontainers.
- Furthermore, we already have established engineering building blocks that we deliberately build upon, such as GitLab CI with reusable pipeline components, Docker and Kubernetes for containerization & deployment, logging & monitoring with Prometheus and Grafana, and Matomo for product-related analytics.
- Of course, our offerings also include the traditional benefits, such as flexible working hours, modern workplaces, JobRad, Hansefit, as well as team events and activities.
- Please note that we do not offer remote jobs and aim for the entire team to be present in our office daily.
- Do you prefer working on-site rather than remotely? Then you are exactly right with us!
