Job description

Redwire Space Missions, LLC is searching for an exceptional Sr. Level Systems Engineer & Space Craft Architect to join our team in Littleton, CO and help architect the next generation of VLEO (Very Low Earth Orbit) spacecraft. This is a high‑impact technical leadership role at the heart of cutting-edge mission design—where you’ll guide full‑lifecycle spacecraft development, shape system architecture, and push the boundaries of what’s possible in VLEO operations.

If you're inspired by complex missions, energized by fast paced, interdisciplinary collaboration, and eager to build spacecraft that operate where few have dared, this is your chance to help lead breakthrough innovation at the forefront of space technology.

Key Responsibilities

• Drive the technical vision—leading system architecture creation, requirements development, design, integration, test, and verification/validation from concept to operations.
• Lead mission-critical milestone reviews including SRR, PDR, CDR, and TRR, ensuring the spacecraft technical baseline is strong, stable, and forward-looking.
• Own and shape spacecraft interfaces across component, subsystem, and system boundaries; manage ICDs and align cross-functional technical teams.
• Plan and execute technical reviews that solidify mission readiness and architectural integrity.
• Perform system-of-systems and architectural analyses to optimize spacecraft performance in unique VLEO environments.
• Guide the development of high-fidelity test assets—including simulations, models, analysis tools, testbeds, and GSE—for both hardware and software evaluation.
• Produce clear, authoritative technical documentation, policies, and procedures.
• Mentor and develop junior engineers, fostering technical excellence and a growth-oriented team culture.

Ideal Experience

• Bachelor’s, Master’s, or Ph.D. in Systems Engineering, Aerospace Engineering, Mechanical Engineering, Electrical Engineering, or related field.
• 10 or more years of relevant engineering experience in the space industry.
• Proven experience across the full space systems engineering lifecycle—from architecture and design through integration, test, and operations.
• Demonstrated leadership experience, guiding technical teams through complex, multi-disciplinary development.
• US citizenship with ability to obtain a DoD security clearance.

Desired Skills

• Familiarity with NASA or DoD spacecraft testing: GEVS/SSC-S-016
• Experience with requirements tools such as JAMA or DOORS.
• Proficiency with Ansys STK for mission and system analysis.
• Background in MBSE approaches and tools.
• Hands‑on experience in technical execution for spacecraft system development.
• Existing DoD clearance.
• Experience with Microsoft Project and Visio.
• Direct experience working with sparse gas environments in VLEO conditions.
