Frontend Software Engineer - React/JavaScript (m/f/d)

The way SIXT builds software is evolving: engineers turn product problems into clear specifications, direct AI coding agents to build them, and own the quality of what ships. As a Frontend Software Engineer (m/f/d), you will operate at exactly this level - delivering primarily through specification and review, backed by the frontend depth to read, debug, and stand behind every change your agents produce. You will turn ambiguous product problems into testable specifications, run end-to-end agent workflows, and own what reaches production. Sounds like your next challenge?
