Senior Software Engineer, Thermal Modeling & Simulation

The posted salary range reflects compensation for our Newark, CA office. Salary ranges for our Michigan location differ and are typically lower.

This role requires employees to be onsite five days a week.

The Role:

• Work with cross-function team to identify thermal plant model requirements for MIL/SIL/PIL/HIL/System Integration testing
• Model in detail thermal components such as heat exchangers, compressors, pumps, valves, vehicle cabin using thermodynamics, fluid mechanics and heat transfer principles using Simulink
• Model in detail thermal behavior of Electrified systems such power electronics, motor-inverter, and other high voltage systems
• Assist in integrating the detailed models with SIL for thermal controls feature verification and validation
• Translate the detailed models to real-time Models to be deployed on Hardware-In-the-Loop (HIL)
• Interface with hardware & controls teams to adapt their models for HIL/SIL closed-loop feature testing
• Work with requirement owners to establish validation metrics for thermal models
  Validate component, sub-system or full thermal system model against actual vehicle data from field
• Document and track modeling issues as appropriate
• Participate in triaging of model issues with various teams to drive towards root cause identification and resolution
• Implement modeling best practices to accelerate development and improve fidelity of models, including runtime performance optimization, model verification and validation
• Help with scalability of model for new and upcoming products
• Participate in the design of a world-class engineering effort to bring electric vehicles to a new level of refinement

 Minimum Qualifications: 

• 5+ years of engineering experience
• 3+ years of experience modeling thermal components such as fans, pumps, fluid connections, heat sinks, heat exchangers, compressors, valves using Simulink or Sim-Scape and other specialized tools
• 2+ years of experience in real-time controls plant modeling for vehicle thermal systems and subsystems
• Extensive experience in electric vehicle thermal management and HVAC systems
• Extensive Experience in deriving ODEs for Heat transfer and thermodynamics
• Strong understanding and experience with the refrigeration cycle (p-h diagram)

Preferred Qualifications:

• Good understanding of MIL/SIL/PIL/HIL simulation methodologies
• Experience with modeling in scalable framework, Simulink libraries, re-usable components, model referencing etc.
• Knowledge of automotive communication protocols such as CAN, LIN, UDS, and related tools to measure and command signals, though scripting or otherwise.
• Experience with revision control tools, such as Git or similar
• Willingness to learn new tools and modeling method
• Experience using real time HIL systems
• Working knowledge of electrified powertrains

Education Qualifications:

• Master’s degree in mechanical engineering with a focus in heat transfer, thermodynamics, and fluid mechanics
