Quality Engineer II

Rockville, MD

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

We are seeking a Quality Engineer II to support hardware build, integration, and test operations across our spacecraft programs. This role is critical to ensuring mission success by driving product quality, process discipline, and continuous improvement throughout Integration & Test (I&T).

This is a hands-on role for someone who thrives in fast-paced hardware environments and can work cross-functionally with engineering, manufacturing, and test teams to identify issues, drive root cause, and implement lasting solutions. You will play a key role in maintaining high-reliability standards across all phases of vehicle assembly and verification.

This is an on-site position in our Rockville, MD office. 

Where You’ll Make an Impact

  • Develop, implement, and maintain quality control procedures, including in-process inspection plans to ensure stable and capable I&T processes
  • Interpret engineering drawings, specifications, tolerances, BOMs, and work orders to verify product conformity
  • Lead investigations into quality escapes and nonconformances using structured root cause methodologies (8D, 5 Whys, Fishbone)
  • Apply industry-standard quality tools and methodologies, including RCCA, SPC, and FMEA
  • Drive corrective and preventive actions (CAPA) to eliminate recurrence and improve overall product and process quality
  • Support continuous improvement initiatives through quality tools and error-proofing techniques
  • Perform, witness, and monitor incoming, in-process, and acceptance inspections and tests across hardware build and pre-launch activities
  • Verify compliance with procedures governing contamination control, cleanroom operations, lifting and handling, hazardous operations, and ESD control
  • Ensure all work is executed against the latest approved drawings and procedures
  • Ensure measurement and test equipment remains within calibration and compliant with program requirements
  • Support internal and external audits, including customer and agency reviews

What It Takes

  • 3–5 years of directly related quality or engineering experience, preferably in aerospace, spacecraft, or other high-reliability hardware environments
  • Strong ability to interpret engineering documentation and verify hardware against requirements
  • Experience leading root cause investigations and driving RCCA/CAPA to closure
  • Hands-on experience supporting hardware integration and test environments
  • Familiarity with environmental testing (thermal, vibration, EMI/EMC)
  • Ability to obtain and maintain NASA and IPC workmanship certifications (J-STD-001, NASA-STD-8739 series); current certifications strongly preferred
  • Strong problem-solving skills and ability to operate effectively in cross-disciplinary teams
  • High attention to detail with a focus on process discipline and execution

Nice-to-Have Experience

  • Current NASA or IPC certifications (J-STD-001, NASA-STD-8739.4, NASA-STD-8739.1)
  • Experience in cleanroom environments and contamination-controlled processes
  • Background supporting spacecraft or flight hardware programs
  • Familiarity with metrology systems, calibration programs, and inspection tooling
  • Experience supporting customer or government audits

What You’ll Get

  • Ownership – Direct impact on spacecraft quality and mission success
  • Exposure – Work closely with engineering, manufacturing, and test teams across the full vehicle lifecycle
  • Growth – Opportunity to develop deep expertise in spacecraft integration and high-reliability systems
  • Compensation – Competitive salary, equity, and comprehensive benefits

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.
