Aeva is building the next generation of sensing and perception for autonomous vehicles and beyond. With its unique ability to measure instantaneous velocity for each pixel, long-range performance at high resolutions, while being free from LiDAR or sunlight interference, Aeva’s 4D LiDAR is built from the ground up at silicon photonics scale for mass-market applications.
We are looking for a Thermal Engineer to join our team and develop thermal solutions for our world-class LiDAR.
What you'll be doing
- Architecting thermal system design to maximize performance and efficiency.
- Developing detailed thermal models to provide design feedback and component requirements.
- Analyzing simulation and measurement results to correlate models.
- Designing convective thermal solutions including fans, heatsinks, and vapor chambers, along with conductive thermal solutions including TIMs and TECs.
- Evaluating thermal impact on optical and electromechanical performance.
- Guiding our overseas CMs and suppliers to execute testing. Reviewing and analyzing data.
What you have:
- 3+ years experience with thermal analysis and modeling of complex systems including silicon packages, PCBs, and fans.
- Experience with multiphysics analysis techniques such as STOP with SigFit.
- Proficiency modeling in Ansys Icepak, FloTHERM, or 6SigmaET (Icepak preferred).
- Experience with PCB, semiconductor package, and system-level thermal testing including test fixture design/simulation/measurement correlation (thermocouples, DAQ, LabVIEW or similar, thermal chambers).
- Experience designing, speccing, and implementing passive and active thermal management solutions.
- Experience debugging system and component-level thermal performance issues and failure analysis.
- Deep understanding of the thermo-mechanical properties and failure modes of glass, laminated composite structures, ceramics, polymers, metals, and adhesives.
- Understanding of CFD model optimization for multi-core efficiency (meshing strategy, feature resolution, understanding how different components affect the thermal stack, etc).
- B.S. in Mechanical Engineering or related field.
Nice to have:
- Experience designing thermal solutions for automotive components.
- Deep understanding of thermal integration manufacturing processes.
- Solidworks modeling experience
- FEA structural simulation experience.
- Magnetics simulation experience with Maxwell, COMSOL, or EMWorks.
What's in it for you:
- Be part of a fast-paced and dynamic team
- Very competitive compensation and meaningful stock grants
- Exceptional benefits: Medical, Dental, Vision, and more
- Unlimited PTO: We care about results, not punching timecards
