Job summary

Anduril Industries in Costa Mesa, CA seeks an experienced Mechanical Engineer to own end-to-end environmental control systems for rugged military shelters. You will work from first-principles sizing to field deployment, collaborating with suppliers and a tight-knit team to deliver mission-ready ECUs in harsh environments.

The role emphasizes vapor-compression systems, thermodynamics, and CFD, with on-site work at headquarters and opportunities to shape a new in-house design capability.

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 fluid 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.

• Excitement to work onsite at our headquarters in Costa Mesa, CA the majority of the time!

Responsibilities

• Own Environmental Control System from concept through real-world use.
• Drive the supplier relationship to specify, evaluate, and refine hardware for mission sets.
• Build the in-house capability to bring HVAC/ECU design fully in-house.
• Size systems for high-ambient cooling, sub-zero heating, and high-latent-load conditions.
• Optimize with CFD and thermal analysis for airflow, coil performance, and packaging.
• Engineer for survival under battlefield conditions through testing and analysis.
• Get hands‑on: build and test prototypes and first articles.
• Deliver at scale with suppliers and manufacturing teams.
