We’re building the future of space, and we need a systems thinker who’s not afraid to get their hands dirty and their minds fired up. As a Senior Systems Engineer, you’ll lead mission-critical efforts across the full lifecycle of space systems — from concept to orbit and beyond. You bring the experience. We bring bold ideas. Together, we make missions happen.

Responsibilities:

• Lead the planning, design, and development of system requirements for space missions
• Evaluate, test, and integrate mission concepts into functional operations
• Define mission goals, validate against system performance, and lead cross-functional teams to achieve those goals
• Work directly with customers to guide mission development from early design through launch and validation
• Own interface definition and management — developing and maintaining Interface Control Documents (ICDs)
• Develop test plans, guide execution, and ensure test results are well-documented and actionable
• Lead key system reviews — SRR, PDR, CDR — and contribute technical leadership to subsystem design (Comm, GNC, ADCS, Propulsion, FDIR, EPS, etc.)
• Support mission ops through coordination, anomaly resolution, and forward-thinking ops planning
• Drive early-phase space system studies for new and upcoming missions
• Proactively identify and manage risks across program phases
• Navigate and support space system regulatory processes (orbital debris assessments, spectrum licensing, etc.)
• Coordinate across a wide range of technical talent, from astrodynamics to systems and navigation engineers
• Support the creation of compelling, technically rigorous proposals for future missions

REQUIRED SKILLS & QUALIFICATIONS:

• B.S./M.S./PhD in Aerospace Engineering or similar, with emphasis on Systems Engineering
• 8–12 years of hands-on experience in mission implementation (flight + ground systems), with deep space experience preferred
• Deep systems-level expertise with a proactive, problem-solving mindset
• Model-Based Systems Engineering (MBSE) experience with tools like Cameo
• Familiarity with NASA’s Systems Engineering Handbook and DoD space programs
• Experience in spacecraft communications systems, mission design, and navigation across Earth, Cislunar, and Deep Space
