Spacecraft Structural Engineer- Level 3

Rockville, MD

Who We’re Looking For

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.

We are seeking a Spacecraft Structural Engineer III to lead the design, analysis, and development of spacecraft structural systems across multiple flight programs. In this role, you will be responsible for ensuring structural integrity from early concept through flight, performing high-fidelity structural analyses, supporting hardware testing, and driving design decisions that balance mass, strength, and manufacturability.

As a senior member of the engineering team, you will work closely with propulsion, avionics, thermal, and systems engineers to ensure structurally sound spacecraft designs while helping guide structural standards, modeling practices, and verification approaches across the company.

Where You’ll Make an Impact

Structural Design & Analysis

  • Lead structural analysis and design efforts for spacecraft primary and secondary structures.
  • Perform detailed analyses including static, modal, vibration, shock, acoustic, and thermal-structural coupling.
  • Develop finite element models to evaluate structural margins across launch and on-orbit environments.
  • Conduct structural trade studies to optimize mass, stiffness, manufacturability, and system integration.

Structural Modeling & Simulation

  • Build and maintain spacecraft finite element models (FEM) using tools such as NASTRAN, FEMAP, ANSYS, or equivalent.
  • Generate analysis-ready models from CAD assemblies (Creo or similar) and ensure consistency between design and analysis configurations.
  • Develop analysis workflows and modeling practices to support rapid design iteration.

Structural Verification & Test Support

  • Define structural verification strategies including analysis-based margin justification and environmental test plans.
  • Support structural testing campaigns including vibration, acoustic, shock, and static load testing.
  • Correlate FEM results with test data and update models to improve predictive capability.

Cross-Functional Integration

  • Collaborate closely with mechanical, propulsion, avionics, GNC, and thermal teams to ensure structural compatibility across spacecraft systems.
  • Participate in design reviews, technical discussions, and program milestones to ensure structural readiness.
  • Identify structural risks early and propose mitigation strategies.

Technical Leadership

  • Provide mentorship and technical guidance to junior structural and mechanical engineers.
  • Contribute to development of internal structural analysis standards, tools, and best practices.
  • Support program leadership with structural insights during key engineering and mission decisions.

What It Takes

  • Bachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or Structural Engineering.
  • 7+ years of experience performing structural analysis for spacecraft, launch vehicles, or comparable aerospace hardware.
  • Strong experience with finite element analysis (FEA) tools such as NASTRAN, FEMAP, ANSYS, Abaqus, or similar.
  • Experience building structural models directly from CAD assemblies (Creo, SolidWorks, NX, or equivalent).
  • Expertise analyzing launch and dynamic environments, including sine/random vibration, shock, and acoustic loads.
  • Experience supporting structural testing and model correlation using real hardware test data.
  • Knowledge of aerospace structural materials, joints, fasteners, and lightweight structural design techniques.
  • Ability to operate independently while collaborating effectively across multidisciplinary teams.

Nice-to-Have Experience

  • Experience with spacecraft structural environments and mission loads.
  • Familiarity with composite structures, thin-walled pressure vessels, or propulsion system structures.
  • Experience supporting environmental test campaigns, including instrumentation and fixture design.
  • Familiarity with Python or MATLAB for analysis automation or post-processing.
  • Experience with fracture mechanics tools such as NASGRO.
  • Familiarity with aerospace structural standards such as NASA-STD-5001, SMC-S-016, or MIL-STD-1540.
  • Experience working in a fast-paced startup or rapid development environment.

What You’ll Get

  • Ownership – Responsibility for spacecraft structural design and analysis across flight programs.
  • Innovation – Hands-on involvement in developing next-generation high-mobility spacecraft platforms.
  • Impact – Your work will directly influence spacecraft flight readiness and mission success.
  • Growth – Opportunities to shape structural engineering practices within a rapidly growing space company.
  • Compensation – Competitive salary, equity, and comprehensive benefits, including medical, dental, vision, generous leave, HSA, 401(k) matching. 

Location: Rockville, MD

Compensation: $125,000 to $175,000 Annual Salary

Voluntary Self-Identification

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.
