Lead Spacecraft Mechanical Engineer

Rockville, MD

Who We’re Looking For 

Quantum Space is transforming how humanity operates in space through highly maneuverable, long-duration spacecraft. We are seeking a Lead Spacecraft Mechanical Engineer to own the design, integration, and verification of all mechanical systems on our spacecraft platforms. 

You will lead a team of engineers and developers building systems that survive launch, operate reliably in space, and enable mission-critical functions including payload support, structural integrity, mechanisms, and thermal control. You’ll be responsible for both technical execution and team leadership as you guide the mechanical and propulsion build effort for our Ranger spacecraft programs. 

Where You’ll Make an Impact 

  • Lead mechanical design and analysis activities for flight hardware and ground support equipment. 
  • Own spacecraft mechanical configurations, including structural layout, payload integration, inertia balancing, and volume optimization. 
  • Hire, train, and develop mechanical engineering staff across multiple programs. 
  • Generate, review, approve, and oversee mechanical and structural design artifacts, engineering drawings, and analysis reports. 
  • Work cradle-to-grave on new spacecraft designs, from initial development through on-site spacecraft build, test, and flight operations. 
  • Prepare, review, and manage subsystem and interface control documents. 
  • Evaluate technical risks, identify cross-functional dependencies, and drive mitigation actions. 
  • Own the development of mechanical hardware and test plans in support of long-term engineering schedules and mission milestones. 
  • Support subcontract procurements through technical evaluation and vendor coordination. 
  • Create and deliver content for design reviews, verification matrices, and environmental test campaigns.  

What It Takes 

  • BS or MS in Mechanical Engineering or a related field. 
  • Minimum of 7 years of relevant spacecraft mechanical design and analysis experience. 
  • Minimum of 3 years of technical team management experience. 
  • Experience with conceptual, detailed design, and integration phases of spacecraft programs. 
  • Strong knowledge of structural design, including high-stiffness, lightweight space structures and pressurized system design principles. 
  • Familiarity with commercial, industry, and other mechanical specifications and standards. 
  • Demonstrated ability to lead cross-functional teams and collaborate effectively across disciplines. 
  • Work location within the Washington DC / Maryland / Virginia (DMV) area. 
  • Proficiency developing large mechanical assemblies in PTC Creo and Windchill. 
  • Strong working knowledge of Geometric Dimensioning and Tolerancing (GD&T) per ASME Y14.5. 
  • Exposure to spacecraft integration, mission readiness reviews, and operations. 

Nice-to-Have Experience 

  • Experience with spacecraft systems for GEO, cislunar,
    and/or deep space missions. 
  • Experience with Microsoft Project or equivalent tools for schedule development and tracking. 

What You’ll Get 

  • Ownership – Lead the execution and design of core mechanical systems for in-space platforms. 
  • Innovation – Shape mechanical architectures that support agile, long-life spacecraft missions. 
  • Impact – Build systems that directly enable critical scientific, defense, and commercial operations. 
  • Growth – Be a technical and organizational leader on a high-performance engineering team. 
  • Compensation – Competitive salary, equity, and comprehensive benefits, including medical, dental, vision, generous leave, FSA, 401(k) matching, and equity sharing. 

Location: Rockville, Maryland

Compensation: $125,000 - $200,000 Annual Salary

Additional Requirements 

To comply with U.S. Government space technology export regulations, including ITAR, applicants must be a U.S. citizen, lawful permanent resident, protected individual per 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State. 

Apply now. Join us in building the mechanical systems that power the future of space exploration.

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in Quantum Space’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
