About the role

Senior Mechanical Engineer responsible for end-to-end environmental control systems (HVAC/ECU) for deployable shelters, from first-principles sizing to fielded hardware, with emphasis on vapor-compression systems, CFD, and rugged environmental performance in military applications.

Responsibilities

  • Own Hardware: Take environmental control systems from concept through real-world use in the hands of warfighters.
  • Drive the Supplier Relationship: Partner closely with HVAC/ECU supplier to specify, evaluate, and refine hardware for mission sets, driving requirements, reviewing designs, and making component and integration trade-offs.
  • Build the In-House Capability: Establish the technical foundation and roadmap to bring HVAC/ECU design fully in-house over time.
  • Size for Extreme Environments: Apply thermodynamics, heat transfer, and psychrometrics from first principles to size systems for high-ambient cooling, sub-zero heating, and high-latent-load conditions.
  • Optimize with Analysis: Use CFD and thermal analysis to evaluate and improve airflow, coil performance, condensation management, and packaging in tightly constrained, ruggedized enclosures.
  • Engineer for Survival: Ensure designs survive battlefield conditions (blowing sand, salt air, shock and vibration, and transport).
  • Get Hands-On: Build and test prototypes and first articles yourself.
  • Deliver at Scale: Iterate on designs and collaborate with suppliers and manufacturing to deliver at volume.]

Qualifications

  • 7+ years of professional mechanical engineering experience, with a focus in HVAC, refrigeration, or environmental control unit design.
  • Demonstrated experience in vapor-compression system design (component selection, sizing, and integration of compressors, heat exchangers and coils, refrigerant circuits, and air-moving equipment).
  • Strong grounding in thermodynamics, heat transfer, and fluid dynamics.
  • High competence with, and fluent use of, engineering first principles.
  • Experience working with suppliers or vendors on hardware design and build.
  • CAD skills (any platform) and the ability to produce high-quality engineering drawings.
  • BS, M.Eng, MS, or PhD in Mechanical Engineering or a related field.
  • Must be a U.S. Person due to required access to U.S. export-controlled information or facilities.
  • Excitement to work onsite at our headquarters in Costa Mesa, CA the majority of the time.
