As a Systems Engineer, you'll drive how our flight vehicle holds together as a system: its subsystems, the interfaces between them, and the evidence that it all works in the environments it has to survive. You'll decompose mission needs into subsystem requirements, define and control interfaces across hardware, software, and electrical domains, and lead the path to verification through bench, environmental, and flight test. You'll work alongside GNC, flight software, avionics, propulsion, structures, and test, and you'll be hands-on in the lab and on the range. If you've taken hardware from concept through qualification and flight, and you want to do it on a system that must work the first time while establishing the appropriate layers of process, this is your chance. 

Key Responsibilities: 

• Develop system architecture and derive, allocate, and maintain subsystem requirements across avionics, propulsion, structures, power, GNC, and flight software 
• Maintain interface control documents (ICDs) for mechanical, electrical, data, and software interfaces, both internally and with suppliers, partners, and customers 
• Build and maintain the system model, keeping requirements, interfaces, and verification traceable 
• Plan and support environmental qualification and acceptance testing: vibration, shock, thermal, thermal vacuum, altitude, humidity, and EMI/EMC, per MIL-STD-810, MIL-STD-461, or program-tailored standards 
• Write test plans and procedures for critical subsystems, and support vehicle-level integration and acceptance testing 
• Own verification and validation, making sure every requirement has a clear method (test, analysis, inspection, demonstration) and a path to closure 
• Support day-to-day technical work across design, software, and test teams, resolving interface conflicts and cross-subsystem issues as they arise 
• Support test data analysis, anomaly resolution, and failure investigations to find root cause and drive corrective actions 

Basic Qualifications: 

• Bachelor's degree in a STEM field 
• 4+ years of engineering experience, with significant time in systems engineering on flight vehicles, missiles, or comparable complex systems 
• Hands-on experience with requirements development and management, interface definition (ICDs), and verification across hardware and software 
• Direct experience planning or executing environmental qualification or acceptance testing 
• Working knowledge across mechanical, electrical, software, and controls disciplines 
• Ability to travel for test campaigns 
• Ability to obtain and maintain a U.S. security clearance 

Preferred Qualifications: 

• M.S. or Ph.D. in engineering, math, or physics 
• Experience taking a flight vehicle or subsystem through qualification and flight test 
• Familiarity with MIL-STD-810, MIL-STD-461, MIL-STD-1540/SMC-S-016, or similar test standards 
• Understanding of aerodynamics, avionics, GNC, and flight systems 
• Proficiency in Python with exposure to C/C++ as a bonus 
• Familiarity with system safety, reliability, and configuration management
