• Analyze telemetry data to optimize thermal performance across duty cycles.

• Collaborate with ERS, electronics, mechanical, and integration teams for system packaging.

• Support prototype testing (dyno, track, thermal cycling) and validation.

• Ensure DFM with suppliers for manufacturability and regulatory compliance.

• Document thermal models, results, and trade-offs for review.

Required Qualifications:

• Bachelor's degree in Mechanical or related field; Master's preferred.

• 3+ years in thermal management, preferably motorsport or high-power electronics.

• Proficiency in CFD/thermal tools (STAR-CCM+, ANSYS, SimScale).

• Strong heat transfer knowledge for electric motors, power electronics, batteries.

• Experience with materials and processes for extreme environments.

• Familiarity with F1 ERS regulations.

Desirable Skills:

• Specific F1 ERS thermal design (MGU-K, CU-K, ES).

• Advanced cooling (oil spray, immersion, phase change).

• Thermal interface optimization and packaging in tight constraints.

• Telemetry analysis and controls integration.

Personal Attributes:

• Results-driven under aggressive timelines.

• Innovative problem-solver balancing trade-offs.

• Excellent cross-functional communicator.

• Detail-oriented with continuous improvement mindset.
