The posting

What is flexhub?

We are Commerzbank's internal delivery capability – a team of engineers, architects, analysts and experts working directly with business units. Unlike external consultancies, we are colleagues who stay. Based in Frankfurt, Sofia, and Łódź, we drive high-priority initiatives while building internal expertise that lasts.

What's in it for you:

Consulting variety meets corporate stability. You join different teams across the bank when your expertise is needed, then move on to the next challenge. This approach helps you build strong internal know-how and gives you the chance to contribute to meaningful work – one initiative at a time – without sales targets or utilization pressure. No selling. Just a consistent focus on engineering solutions that matter.

As a Professional Backend Developer at flexhub, you engineer robust solutions that serve our customers reliably. You take ownership of specific components, designing and implementing Java-based services with minimal supervision. Your work directly impacts the stability and speed of our banking platform. By solving technical problems independently, you help the team meet its delivery goals sprint after sprint. Your main tasks are:

  • Primary Action: Design and implement complex backend logic using Java and the Spring ecosystem.
  • Integration: Integrate third-party services and internal systems using secure REST or messaging protocols.
  • Implementation: Translate business requirements into functional, high-performance code.
  • Quality: Write comprehensive tests and conduct thorough code reviews to maintain high standards.
  • Collaboration: Actively contribute to sprint refinement and estimate technical tasks with the team.
  • Operations: Deploy your services to production and troubleshoot incidents when they occur.
  • Documentation: Create detailed technical specifications and architecture diagrams for your components.
  • Learning: Keep up with Java updates and share interesting findings with your peers.
  • Stakeholder: Explain technical challenges to product owners in understandable language.
  • Improvement: Refactor legacy code to improve performance and maintainability.

What is important for us? 👌

  • Java
  • Spring Framework
  • RESTful Web Services
  • SQL
  • Git
  • Object-oriented Design
  • Unit Testing
  • Agile Methodologies
  • Problem Solving
  • Technical Documentation

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
