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 Senior Fullstack Developer at flexhub, you shape the technical direction of our entire domain. You orchestrate the development of large-scale systems, set coding standards, and act as a trusted advisor to management. Your authority in fullstack engineering ensures we build secure, maintainable, and future-proof solutions. You turn abstract business goals into concrete technical roadmaps.
Your main tasks are:
- Primary Action: Shape the overall system architecture and ensure alignment with enterprise standards.
- Integration: Orchestrate the integration of complex legacy systems with modern cloud-native services.
- Implementation: Define the coding standards and patterns that all teams must follow.
- Quality: Set the bar for code quality and security across multiple development squads.
- Collaboration: Facilitate cross-team technical workshops to align on shared dependencies.
- Operations: Lead the response to major incidents and define stability patterns like circuit breakers.
- Documentation: Create high-level system maps and data flow documentation for auditors.
- Learning: Lead technical communities of practice to spread knowledge across flexhub.
- Stakeholder: Partner with business leaders to align technical investments with business value.
- Improvement: identify systemic inefficiencies and drive large-scale refactoring initiatives.
