About the role

  • Design and build thermal test assets spanning a range of size, scope and complexity: this could range from a simple coolant bench test to characterize a valve, to a partially completed refrigeration system with coolant and air loops, to a fully instrumented vehicle.
  • Automate / script HIL testers that can replicate boundary conditions, loads etc. felt by a thermal system across a wide range of possible scenarios.
  • Work with modeling engineers to validate predictions – propose tests based on prediction weaknesses, learn how to run the models themselves.
  • Collaborate closely with controls engineers to validate the SW and propose improvements.
  • Work closely with test and integration engineers to debug control algorithms at the bench and vehicle level.
  • Lead engineering test fleets – these may consist of bucks and/or vehicles.
  • Plan critical test campaigns – both at the wind tunnel and in the field.

Requirements

  • B.S. in Mechanical Engineering or a related field.
  • Foundational background in thermal systems (heat transfer, thermodynamics, fluid dynamics).
  • 4+ years of experience using modeling tools of various scales (GT, Python, MATLAB/Simulink, Dymola, TAITherm or similar).
  • Experience with basic programming best practices (e.g., readable, re-usable code).
  • Experience working with high voltage powertrain and thermal systems
  • Experience diagnosing and repairing HVAC components and systems
  • Safe management of glycol, AC refrigerant, and oil-based liquids and gases
  • Knowledge of thermal and fluid measurement sensor installation and calibration
  • Experience with data acquisition systems and related sensors
  • Can interpret and create wiring diagrams for test fixture construction
  • Even better, you may have...
  • Graduate Degree in Mechanical Engineering with a focus on thermal engineering or energy systems.
  • Real-world product development experience using tests to design, validate and continuously improve a thermal system used by customers every day.
  • Deep experience with refrigeration systems (compressors, heat exchangers, valves, sensors, charge and oil management) applied to automotive products.
  • Deep experience with HVAC design (hardware, control strategies, energy flows within the cabin, glass properties).
  • Experience modeling non-linear flow/energy circuits with first principles.
  • Familiarity with battery, motor/inverter and electronics thermal/electrical models.
  • Familiarity using 3D CAD software collaboratively (NX, Catia, 3DX).
  • Proficiency using collaborative work tracking tools such as JIRA, Confluence and GitHub
  • Testing/laboratory experience with refrigeration loops, coolant and air circuits.
  • An eagerness to work cross-functionally in a dynamic environment where you are part of a high performing team.
  • A system approach to design and development with the desire and curiosity to strive for exceptional delivery execution and continuous improvement.
  • Experience with controls methods for automotive thermal systems

Benefits

  • Immediate medical, dental, vision and prescription drug coverage
  • Flexible family care days, paid parental leave, new parent ramp-up programs, subsidized back-up child care and more
  • Family building benefits including adoption and surrogacy expense reimbursement, fertility treatments, and more
  • Vehicle discount program for employees and family members and management leases
  • Tuition assistance
  • Established and active employee resource groups
  • Paid time off for individual and team community service
  • A generous schedule of paid holidays, including the week between Christmas and New Year’s Day
  • Paid time off and the option to purchase additional vacation time.
