Job Summary
In this role, you will develop Java applications for i-effect®, design architecture and interfaces, and take ownership of your features from concept to production in an agile team environment.
Job Technologies
Your role in the team
- Further develop Java applications for i-effect® (EDI conversion, ZUGFeRD/XRechnung, IBM Power i).
- Design and implement custom software for client projects within a team.
- Shape architecture and interface design. You don't just work through tickets; you help shape modules.
- Ownership: you accompany your feature from the initial concept through implementation to production operation. "You build it, you run it."
- Typical week: starting with architecture sketching and team discussion, middle of implementation with Claude Code as a sparring partner and own tests, end with internal demo and handover to sales. Sprint rhythm is classically agile, without every day being packed with meetings.
