Descrizione del lavoro

Quantum Space in Rockville, MD / Hawthorne, CA, seeks an experienced Mechanical Engineer III to lead flight hardware design and testing for next‑gen spacecraft.

You will own mechanical subsystems from requirements through assembly and test, collaborating across engineering, AIT, and manufacturing teams.

Competenze

• Bachelor's or Master's in Mechanical Engineering or related field.
• 7+ years of aerospace/space hardware development experience.
• 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.

Mansioni

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

Descrizione del lavoro

Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly.

Who We’re Looking For

We are seeking an experienced and highly motivated Mechanical Engineer III to lead the design, development, integration, and testing of flight hardware for our next-generation spacecraft programs. In this role, you will take ownership of mechanical components and subsystems throughout the full hardware development lifecycle, from requirements definition and detailed design through manufacturing, assembly, integration, and testing.

You will play a critical role in ensuring the performance, reliability, and manufacturability of mission-critical spacecraft hardware while collaborating closely with mechanical engineering, systems engineering, assembly, integration and test (AIT), and manufacturing teams. This position is ideal for an engineer with strong mechanical design expertise, hands‑on flight hardware development experience, and the ability to independently lead technical execution in a fast‑paced, collaborative environment.

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

• Bachelor's degree or Master's degree 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

Nice-to-Have Experience

• Experience writing or reviewing work instructions / build travelers
• Familiarity with environmental testing and test readiness processes

What You’ll Get

• Ownership – Lead mechanical design and development of mission‑critical spacecraft hardware from requirements through integration and testing
• Innovation – Contribute to next‑generation spacecraft technologies enabling advanced space mobility, maneuverability, and mission capabilities
• Impact – Play a direct role in delivering reliable, high‑performance spacecraft hardware supporting national security, civil, and commercial missions
• Growth – Join a collaborative, fast‑paced engineering team where you can expand your technical expertise, take ownership of meaningful projects, and help shape the future of space technology
• Compensation – Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, FSA, 401(k) matching, and equity sharing

Location: Rockville, MD or Hawthorne, CA
