Mechanical Engineer, Propulsion Integration

Oxnard, California, United States

Swarm Aero is redefining air power, building the largest swarming UAV and most versatile swarming aircraft network in the world. The company is moving quickly to launch the first aircraft designed specifically for swarming as well as the Command & Control software to mobilize swarms of thousands of heterogeneous autonomous assets and empower human operators to achieve superhuman results. 

The team has created and exited multiple startups, negotiated defense deals worth billions of dollars and designed and built 30+ novel aircraft, with aerospace experience from Scaled Composites, Airbus, Archer Aviation, Blue Origin, and Boom Supersonic

As a Mechanical Engineer focused on propulsion integration, you will own how our propulsion system physically and functionally integrates into the aircraft. You’ll collaborate closely with powerplant suppliers, systems engineers, and the airframe team to ensure the engine and its supporting systems fit, perform, and operate safely under demanding mission profiles. This is a hands-on role requiring strong design intuition, systems awareness, and the ability to translate theoretical requirements into flight-ready hardware. 

Key Responsibilities 

  • Lead mechanical design and integration activities related to propulsion systems and subsystems (mounts, ducts, fuel, electrical interfaces, vibration isolation, etc.). 
  • Serve as the primary engineering point of contact for propulsion integration—coordinating between internal structures, systems, and flight test teams and external engine partners. 
  • Develop and maintain 3D CAD models, installation drawings, and integration assemblies that define propulsion fit and function. 
  • Conduct trade studies on layout, mass properties, thermal management, and maintainability. 
  • Collaborate with stress, thermal, and aerodynamics engineers to ensure safe and efficient engine operation. 
  • Support prototype builds and flight tests by resolving integration and installation issues. 
  • Generate design documentation, test procedures, and reports to support manufacturing and certification activities. 
    Identify risks early and propose practical design mitigations or improvements. 

Basic Qualifications 

  • Bachelor’s degree in Mechanical or Aerospace Engineering (or related discipline). 
  • 5+ years of experience in propulsion integration, powerplant systems, or aircraft mechanical design. 
  • Proficiency in 3D CAD (SolidWorks, NX, or CATIA) and GD&T fundamentals. 
    Strong understanding of structural design, vibration, and thermal environments typical of propulsion systems. 
  • Experience working cross-functionally with manufacturing, suppliers, and test teams. 
  • Hands-on experience with hardware integration, assembly, or flight testing. 

Preferred Qualifications 

  • Experience with gas turbine, piston, or hybrid-electric propulsion installations. 
  • Familiarity with fuel, oil, and cooling systems integration. 
  • Understanding of engine mount design and vibration isolation. 
  • Exposure to lightweight aircraft, UAVs, or experimental platforms. 
  • Ability to thrive in a fast-paced, iterative engineering environment. 

 

What we Offer:

  • Meaningful equity stake in a high-growth defense technology company
  • Competitive base salary commensurate with experience
  • Comprehensive benefits including medical, dental, vision, and 401k
  • PTO and Paid Sick Time
  • Monthly Wellness Stipend
  • Daily catered lunch to office
  • Paid Parental leave
  • Flexible work arrangement - remote/hybrid with regular collaboration in Oxnard
  • Direct impact opportunity - be a key leader in building a critical technology for national security
  • World-class team - work alongside exceptional engineers and operators solving hard problems

Compensation Range:

  • $150,000 - $190,000 + Equity

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.
