HIL Test Engineer

= Position: HIL Test Engineer
= Location: Mossville, IL
Duration: 2+ years (Contract)
=' Client : Caterpillar

Position Description:

seeking a Hardware-in-the-Loop (HIL) Test Engineer with demonstrated, hands-on experience working directly with HIL benches and physical hardware. This role requires more than executing pre-written test scripts; it demands strong hardware-side troubleshooting skills, critical thinking, and the ability to diagnose real-world system issues at the bench.

Candidates must be comfortable working in-person with HIL systems, sensors, wiring, and instrumentation. Experience limited to remote access or script-only testing will not meet the expectations of this role.

Key Responsibilities

• Perform hands-on operation of HIL benches, including setup, configuration, and maintenance of physical hardware
• Troubleshoot hardware and signal-level issues such as open circuits, sensor faults, wiring problems, and signal integrity issues
• Analyze unexpected test results and independently determine root causes rather than relying solely on predefined test plans
• Collaborate with controls, software, and systems engineers to resolve integration and hardware-related issues
• Execute and, when necessary, adapt or improve test procedures based on real-time observations at the bench
• Document findings clearly, including hardware failures, corrective actions, and lessons learned

Required Qualifications

• Proven hands-on, physical HIL experience (not limited to remote bench access or script execution)
• Strong understanding of electrical fundamentals, sensors, I/O, and signal troubleshooting
• Demonstrated ability to think critically and solve problems beyond following step-by-step instructions
• Experience diagnosing hardware issues such as disconnected signals, faulty sensors, and unexpected system behavior
• Comfortable working directly with test equipment, wiring, and HIL hardware components
