Needs integration support in Michigan he has a team of 3 there at present

This role is very software focused - hybrid role must be well versed in high voltage safety fundamentals batteries and cell technology but strong on the embedded software side of things as well

This role is open due to increased workload they need more heads to get through peak while they are ramping up battery manufacturing they need to help manufacturing with end of line test fixtures helping battery pack teams and other stuff

This is a BMS centric role reviewing test plans reviewing data from pack tests they are testing packs on pack cyclers 24/7 ensuring controls are robust they do tuning optimization they will work closely with the algorithm teams there is another team doing baseline firmware software and another team focused on algorithms and controls this person works closely with the controls people to ensure they are getting expected performance on the pack

This person will be very hands-on jumping into the code jumping into hardware schematics to find hardware issues. They will be more of a software person but with hardware experience too.

They will have features like optimizing a thermal management controller and they have test benches for those controllers and this person will put together test plans and integrations to interface with the thermal controls team. Theyre controlling coolant temp and flow rate and need to validate those features.

HV and automotive is key.

He is open to 4-12 years of experience Staff level is one step above Sr.

Embedded software experience is a hard requirement

Automotive experience is a hard requirement

Battery for automotive experience is a hard requirement

Basic EE background is a hard requirement

Embedded C is a hard requirement

Vector-based software tools CANalyzer CANoe Canopy is a hard requirement

Simulink is a strong nice to have

Python is nice to have

Candidates coming from Rivian Tesla and other newer Auto companies work well but supplier companies and traditional big 3 auto is also ok
