Summary
🤩
Rockstar🎓
Top SchoolSebastian Jahr is a Senior Robotics and Trajectory Planning Engineer based in Heidelberg with seven years of hands-on experience building and hardening robot motion stacks. He has progressed from research roles and internships at KIT, FZI and Franka Emika to product-focused engineering at PickNik and a current senior role at ZEISS, bringing deep expertise in planning, joint-limit handling and test automation for ROS/MoveIt ecosystems. An active open-source contributor, Sebastian has improved MoveIt2 tutorials, migrated test suites, and fixed release-crashing issues in libfranka—work that underscores his focus on reliability, documentation, and developer experience. He combines strong C++ and backend skills with a track record of translating research-grade planners into production-ready, well-tested software. A less obvious strength is his emphasis on clear documentation and tutorials, which amplifies adoption and reduces onboarding friction across robotics teams.
