Senior Mechanical Engineer - Spacecraft Programs

Who We’re Looking For

Quantum Space is seeking a Senior Mechanical Engineer to own flight hardware development on our Spacecraft Programs. This role is built for an engineer who can take a subsystem/component from requirements to a released design, through build, integration, and test—while collaborating tightly with AIT and manufacturing.

Senior-level expectations include independent ownership of deliverables and leadership of technical execution for meaningful scopes.

Where You’ll Make an Impact

Own mechanical components/subsystems end-to-end: requirements, design, analysis coordination, release, and integration support

Develop CAD and drawings in Creo; apply GD&T and define inspectable requirements

Drive interface closure: envelope/keep-outs, fastener patterns, datums, alignment needs, harness/thermal accommodations

Support spacecraft build and integration: issue triage, rapid root-cause collaboration, and corrective design updates

Develop and execute verification plans: functional checks, fit checks, environmental test prep support, and acceptance/qualification evidence generation

Support design reviews (PDR/CDR), test readiness reviews, and configuration boards with clear technical content

Coordinate with suppliers and procurement: clarify requirements, review vendor designs, and support receiving/inspection disposition

What It Takes

BS or MS in Mechanical Engineering or related field

7+ years relevant experience with aerospace/space hardware development 

Proficiency in Creo; working knowledge of Windchill or similar PLM

Strong GD&T fundamentals (ASME Y14.5) and drawing package quality discipline

Experience supporting hardware through build/test cycles, not just design-in-a-vacuum

Work location within the DMV area

Nice-to-Have Experience

Spacecraft integration exposure: mass properties, alignment, configuration capture, as-built management

Experience writing or reviewing work instructions / build travelers

Familiarity with environmental testing and test readiness processes

What You’ll Get

Ownership – Real flight hardware responsibility

Impact – Direct contribution to mission success

Growth – Path to subsystem leadership and principal ownership

Compensation – Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity participation.
