Thermal Engineer

About the company

Our client is a robotics company.

The role

Raydar is recruiting for this role on behalf of our client. Develop cooling approaches for small robotic drive units, building analytical and simulation tools and then confirming them on physical prototypes. The position collaborates with electric-machine, power-electronics and mechanical colleagues so that equipment keeps running reliably under demanding operating patterns.

What you'll do

- Turn loss figures from electric machines and inverters, plus expected robot usage patterns, into thermal targets and boundaries.

- Build detailed simulation models and simpler reduced-order models, then tie them to measurements from instrumented hardware.

- Engineer the cooling hardware and heat-flow pathways, and define the fluid flow, pressure, pumping and heat-removal targets the system must meet.

- Work with mechanical designers on fluid lines that cross articulated joints, taking into account movement, upkeep access, seals, chemical compatibility and possible leaks.

- Design and carry out temperature testing under varied surroundings and shifting workloads, track down overheating areas and confirm each change works.

- Hand off test-based temperature ceilings and model data to controls and embedded software teams for performance-throttling logic, and help suppliers and production teams validate parts.

Requirements

What we're looking for

- Bachelor's or master's degree in engineering or a closely related field.

- Familiarity with fluid plumbing, tight seal designs, leak checks or whether coolants suit the materials used.

- Practical use of simulation packages for coupled heat flow or fluid dynamics, plus resistance-network modeling and matching predictions to measurements.

- Solid working knowledge of how heat moves through solids and fluids, including circuit-style thermal analysis.

- Experience cooling motors, battery packs, inverters, servo drives or compact robotic joints.

- Track record of creating workable cooling parts and confirming their performance with temperature, flow and pressure readings.

- Ability to work on-site in Fremont, CA. Relocation support is not provided.

Bonus points

- Background in consumer electronics.

- Prior work building and trialing liquid-cooled machinery or power equipment.
