Job description

About Harbinger

Harbinger Motors Inc. is a Southern California-based electric vehicle manufacturer on a mission to transform the automotive and transportation industries, bringing to market EVs developed from the ground up to address the needs of the Medium Duty vehicle industry. This broad, and to date poorly addressed, market segment includes class 4 to 7 commercial delivery vehicles, RVs and utility vehicles, among others. Leveraging a foundation of proprietary, in‑house developed vehicle technologies, Harbinger's first‑of‑its‑kind EV platform will bring enhancements in vehicle performance, durability and operator comfort. And importantly, Harbinger’s vehicles will be priced for zero acquisition premium relative to traditional gas‑ and diesel‑based competitors, removing one of the most tenacious barriers to EV adoption.

Harbinger’s team, with operations in Southern California and Michigan, includes industry veterans with expertise in powertrain, battery, chassis and software development, along with leaders in advanced manufacturing, corporate development, operations and finance. Our team members come from leading innovators, both in and out of the automotive industry, including Tesla, Rivian, Canoo, Ford, Anduril, and SpaceX.

Founded in 2021, Harbinger is a venture‑backed startup on a rapid growth trajectory, looking for candidates that thrive on tackling complex challenges and who share in our passion to bring clean transportation alternatives to a segment of the market starving for innovation.

The Thermal Engineering team is looking for a seasoned thermal analysis engineer to support the future of medium duty trucks. The candidate will be responsible for developing thermal simulations to support the design and development of electric motors, batteries, power electronics and more. You will also be expected to work with test engineers to validate your simulation results and provide feedback to the design team to improve the product’s performance and reliability. Applicants should thrive in a fast‑paced startup environment and be able to collaborate well with cross‑functional teams.

What you will do

• Develop and document thermal simulations for various vehicle components in a 3D simulation environment.
• Assess the thermal performance of vehicle components under both steady‑state and transient conditions, providing performance recommendations to design engineers.
• Document and post‑process simulation results in an organized manner.
• Develop test plans and support the test team in gathering data from physical systems.
• Iterate simulation models to achieve strong correlation and build confidence in results.
• Use simulation models and tools to identify root causes of issues observed during testing and provide feedback to improve reliability.

Who you are

• Hold a Bachelor’s degree or an equivalent relevant educational credential.
• Have 5+ years of experience in thermal and/or fluid analysis.
• Demonstrate strong proficiency in STAR‑CCM+ or similar analysis tools.
• Possess the ability to run large simulation models on HPC clusters.
• Communicate simulation results effectively in both oral and written formats.
• Exhibit strong problem‑solving skills and the ability to collaborate in a dynamic team environment.
• Bring hands‑on experience in testing automotive components.
• Experience with multi‑phase simulations (e.g., VoF or Mixture Multi‑Phase) is a significant plus.
• Familiarity with 1D analysis tools is considered a bonus.

Benefits and Compensation

• 100% Comprehensive Health Coverage: You are covered with top‑tier medical, dental, and vision insurance.
• Accelerate Your Wealth: As an early‑stage employee, you’ll have the opportunity to rev up your financial future with early‑stage stock options.
• Unleash Your Time: Take control of your work‑life balance. Salaried teammates receive flexible PTO and the freedom to celebrate holidays and wellness days as you see fit.
• Cruise Into Vacations: Enjoy an exciting annual vacation stipend to help you recharge your batteries.
• Fuel Your Day: We provide paid lunches and dinners to keep you energized.
