Senior Mechanical Engineer - Spacecraft Programs

Rockville, MD

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.

Location: Rockville, MD

Compensation: $145,000 to $195,000 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.

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.
