W2 or 1099 role for Caterpillar.
Electrical Engineer Simulation
Mossville, Illinois (Onsite) Local / Non local both fine
Long Term Contract
Job Description.
Join the CAT Simulation team supporting Caterpillar's electrification efforts. This role leads simulation-driven assessment of electric machines, power electronics, and battery systems-centered on system-level performance, energy, and thermal analysis across electrified drivetrains. Highly technical and cross-functional; not manufacturing-focused.
What You'll Do
Translate machine load conditions, torque/speed curves, and duty cycles into energy consumption, thermal performance, and system-level metrics for electrified drivetrains.
Model and analyze electric machines & motor drives, power electronics (inverters/converters, IGBTs/MOSFETs, junction temperature, thermal margins), and battery systems (SOC dynamics, charge/discharge impacts).
Evaluate range of electrical output and load calculations; conduct thermal analysis of high power systems (hundreds of kW to MW).
Integrate results across motor power electronics battery subsystems and quantify tradeoffs in performance, efficiency, cost, and mass.
Support machine control and system performance assessments using simulation.
Collaborate with cross functional teams to obtain/validate inputs, review results, and inform program decisions.
Use internal proprietary tools alongside commercial software.
Must-Haves
BS in Electrical Engineering - 10+ years relevant experience.
Proven experience with electrified powertrain systems simulation and power conversion analysis.
Thermal applications/analysis across electric machines, power electronics, and batteries.
Battery and power electronics expertise (energy storage + conversion).
Strong analytical skills and engineering judgment-able to interpret results, not just run models.
Top 3 Priorities
1. Simulation tools expertise: MATLAB/Simulink, ANSYS (incl. CFD), SimPro
2. Cross team collaboration and communication
3. Detailed power conversion analysis; thermal experience highly desirable
Nice-to-Haves
ANSYS Maxwell (electromagnetics); CFD/thermal (steady & transient)
Power electronics tools (PLECS, Simplorer, similar)
Battery modeling and system level energy analysis
Programming not required, but MATLAB scripting/integration is a plus
