> Design, build, and integrate hardware-in-the-loop (HIL) benches replicating vehicle electrical/electronic architecture. Lead ECU integration, harness design, Python automation, debugging with bus tools, validation, and cross-functional coordination for autonomy platforms.

## Job Description

## Responsibilities
- Lead system-level integration and bring-up of HIL benches replicating vehicle E/E behavior.
- Design and assemble bench hardware — wire harnesses, breakout boxes, load simulation, power distribution, and instrumentation — for ease of assembly, serviceability, and robust operation.
- Develop tooling and automation in Python for ECU flashing, test orchestration, and bench health monitoring integrated into CI pipelines.
- Debug internal hardware and software issues using oscilloscopes, and bus analysis tools across CAN, CAN-FD, LIN, and Automotive Ethernet.
- Conduct network compatibility and protocol compliance reviews to validate interoperability of sensors, ECUs, and actuation subsystems on the bench.
- Define acceptance criteria, execute bench- and vehicle-level validation, and drive root cause analysis to closure.
- Maintain platform documentation including bench schematics, integration procedures, failure mode analyses, and action reports.
- Interface cross-functionally with software, hardware, and program teams to drive delivery, tracking integration tasks and defects in JIRA.

## Requirements
- BS or MS degree in Electrical, Computer, Systems Engineering, or equivalent program.
- 2-3+ years of experience in vehicle E/E systems integration, HIL bench development, or vehicle-level validation.

## Nice-to-Haves
- Experience with commercial HIL and real-time simulation platforms (e.g., dSPACE, NI, Vector, Speedgoat).
- Experience creating harness and subsystem schematics using Siemens Capital or similar ECAD tools.
- Model-based development experience with MATLAB/Simulink.
- Experience supporting factory or vehicle launch bring-up under tight timelines.
- Excellent written & oral communication skills – ability to present to wider audiences.
