Mechanical Engineer II - Spacecraft Programs

Job Description

Quantum Space is redefining mobility and autonomy beyond Earth orbit. Our Ranger spacecraft deliver high delta-V and sustained on-orbit maneuverability, enabling missions across cislunar and geostationary space that were previously out of reach. We are building the vehicles, infrastructure, and operational expertise that connect and protect assets across the Earth–Moon system.

Who We’re Looking For

Quantum Space is seeking a Mechanical Engineer II to contribute to the development of flight hardware across our Spacecraft Programs. This role is intended for an engineer who can independently execute well-scoped components or subassemblies and support hardware through build, integration, and test.

You will begin taking ownership of design deliverables while collaborating closely with AIT, manufacturing, and senior engineers.

Where You’ll Make an Impact

Own design of components and subassemblies from requirements through release
Develop CAD and drawings in Creo; apply GD&T with increasing independence
Drive interface definition: mounting features, tolerances, datums, and packaging constraints
Perform basic structural and thermal analysis (hand calcs and FEA support)
Support hardware integration: troubleshoot issues, propose fixes, and implement design updates
Contribute to verification planning and execution: fit checks, functional validation, and test support
Participate in design reviews (PDR/CDR) with clear technical communication
Coordinate with suppliers: review drawings, clarify requirements, and support part acceptance

What It Takes

BS or MS in Mechanical Engineering or related field
2–5 years of relevant experience with hardware development
Proficiency in Creo (or similar CAD) and experience releasing drawings
Working knowledge of GD&T (ASME Y14.5)
Experience supporting hardware through build/test cycles
Strong problem-solving and troubleshooting ability
Work location within the DMV area

Nice-to-Have Experience

Experience with FEA tools (ANSYS, Nastran, etc.)
Exposure to spacecraft or aerospace systems
Familiarity with PLM systems (Windchill or similar)
Experience working with suppliers and manufacturing teams

What You’ll Get

Ownership – Real contribution to flight hardware early in your career
Mentorship – Direct learning from experienced spacecraft engineers
Growth – Clear path to subsystem ownership
Compensation – Competitive salary, equity, and comprehensive benefits

Location: Rockville, MD

Compensation: $100,000 to $140,000 Annual Salary Depending on Experience
