Mechanical Engineer I - Spacecraft Programs

Rockville, MD

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 I to support the development of flight hardware for our Spacecraft Programs. This role is designed for an early-career engineer who wants to build strong fundamentals by contributing to real hardware from concept through integration and test.

You will work closely with experienced engineers, AIT, and manufacturing teams to execute well-defined scopes while learning how flight hardware is actually built, not just designed.

Where You’ll Make an Impact

  • Support design of mechanical components and simple subsystems under guidance
  • Create CAD models and detailed drawings in Creo, applying GD&T with mentorship
  • Assist in interface definition: envelopes, mounting schemes, and basic alignment features
  • Support hardware builds and integration activities, including hands-on work when needed
  • Assist with issue triage and root-cause investigations during integration and test
  • Contribute to verification efforts: fit checks, basic functional checks, and test documentation
  • Prepare clear documentation for design reviews and configuration tracking
  • Support supplier coordination through drawing clarifications and basic review feedback

What It Takes

  • BS in Mechanical Engineering or related field
  • 0–2 years of relevant experience (internships or project teams acceptable)
  • Exposure to CAD (Creo preferred, but not required)
  • Basic understanding of engineering drawings and GD&T principles
  • Strong fundamentals in mechanics, materials, and design
  • Willingness to work hands-on with hardware in a lab/integration environment
  • Work location within the DMV area

Nice-to-Have Experience

  • Internship or academic project involving hardware build/test
  • Exposure to aerospace or space systems
  • Familiarity with basic analysis tools (FEA, MATLAB, or Python)
  • Experience with machine shop tools or prototyping

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: $75,000 to $125,000 Annual Salary Depending on Experience

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 required authorizations.

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.
