Sr Staff Engineer, HVAC + Thermal Systems

About the role

Aptera is seeking a Senior Staff Engineer, HVAC & Thermal Systems to lead thermal architecture and HVAC system development for our solar electric vehicle. In this role, you'll define and execute the thermal strategy that keeps our vehicle's occupants comfortable and its battery, powertrain, and electronics running efficiently, all while protecting the ultra-low energy consumption that makes Aptera's solar vehicle possible.

What you'll do

• Lead the design, development, and vehicle validation of HVAC and thermal management systems for Aptera's solar vehicle platform, including battery thermal management (all systems), cabin climate control, and power electronics cooling
• Define thermal architecture strategy that balances energy efficiency, range, and occupant comfort, a critical trade-off given the vehicle's ultra-aerodynamic, solar-charging design
• Own thermal system requirements, specifications, and performance targets from concept through production
• Lead HVAC calculations and simulation work (CFD, 1D/3D modeling) to predict, validate, and optimize system performance ahead of physical testing
• Plan and lead HVAC system validation and thermal programs, including climate chamber testing, hot/cold weather development, and real-world performance verification
• Partner cross-functionally with battery, powertrain, body, and electrical teams to integrate thermal systems into the overall vehicle architecture
• Select and manage relationships with HVAC and thermal component suppliers, including compressors, heat exchangers, refrigerant systems, and heat pumps
• Provide technical leadership and mentorship to junior and mid-level HVAC and/or thermal engineers
• Drive root-cause analysis and resolution of thermal-related field and test issues
• Ensure HVAC system designs comply with relevant automotive thermal and refrigerant safety standards
• Maintain accurate HVAC and thermal systems documentation within the vehicle's Build of Materials (BOM)

Qualifications

• 15+ years of relevant experience in automotive HVAC, thermal systems, or thermal management engineering
• Deep expertise in vehicle HVAC systems and thermal architecture, including battery thermal management systems for electric vehicles
• Proven track record leading thermal system design from concept through production launch
• Strong background in CFD and thermal simulation tools
• Hands-on experience with climate chamber and physical thermal validation testing
• Experience with HVAC systems and its major components and technologies
• Strong cross-functional collaboration skills, working closely with battery, powertrain, and body engineering teams
• Demonstrated technical leadership and mentorship of engineering teams
