Summary
🤩
Rockstar🎓
Top SchoolSteve Kieffer is an experienced aerospace engineer with 13+ years leading flight operations, ascent trajectory design, and in-flight maintenance for Space Shuttle missions, including multi-million dollar hardware inspections and crew integration. He has a proven record directing multinational astronaut teams and coordinating complex launch, landing, and post-landing activities while authoring operational procedures and requirements for onboard avionics and display systems. Technically versatile, Steve pairs mechanical aptitude and UNIX/CAD skills with hands-on QA/QC and real-time mission problem solving—once contributing to a saved mission and earning his company's highest award. He also contributes to open-source mathematical software, extending algebraic number theory features in the widely used SymPy project. Based in La Marque, Texas, he holds a BS in Aerospace Engineering and additional certifications in project management and offshore safety, and is willing to travel or relocate for mission-critical work. Notably, his background bridges flight software, trajectory design, and practical hardware fit-checks—a rare combination of theory and field-proven execution.
