Job Overview

• We are seeking a HIL Engineer responsible for building, setting up, integrating, and commissioning Hardware-in-the-Loop (HIL) test benches for automotive electronic control units (ECUs).
• The engineer will be responsible for the complete HIL bench setup, including hardware installation, electrical wiring, ECU connections, I/O configuration, communication networks, power supplies, signal interfaces, and system integration. The role requires a hands-on engineer who can troubleshoot the bench at the hardware and software level and prepare the HIL environment for testing and validation.

Key Responsibilities

• Build and configure HIL test benches for automotive ECU testing and validation.
• Install and integrate HIL hardware, including HIL simulation systems, ECU interfaces, I/O modules, power supplies, signal conditioning units, load boards, relay/switching systems, and measurement equipment.
• Perform electrical wiring and physical connections between ECUs, HIL systems, breakout boxes, loads, sensors, and other test equipment.
• Configure ECU power, ignition, ground, analog, digital, PWM, frequency, and other required signals.
• Configure and troubleshoot automotive communication networks such as CAN, CAN FD, LIN, FlexRay, and Ethernet.
• Set up communication interfaces, network termination, routing, and signal connections.
• Configure HIL I/O channels and map ECU signals to the simulation environment.
• Support ECU installation, removal, and connection to HIL benches.
• Perform bench commissioning, bring-up, and functional checks before testing begins.
• Verify wiring, pinouts, connectors, voltage levels, signal integrity, and communication interfaces.
• Troubleshoot HIL bench hardware, electrical, communication, and configuration issues.
• Use electrical schematics, wiring diagrams, ECU pinouts, interface specifications, and system documentation to build and troubleshoot test setups.
• Configure and maintain HIL system software and associated test environments.
• Support integration of plant models and real-time simulation environments.
• Work with test and validation engineers to prepare the HIL bench for automated and manual testing.
• Document bench configurations, wiring, hardware changes, issues, and troubleshooting activities.
• Maintain HIL benches and support upgrades, modifications, and new ECU integrations.

Required Qualifications

• Engineering degree or equivalent technical background in Electrical Engineering, Electronics, Computer Engineering, Mechatronics, Automotive Engineering, or a related field.
• Hands-on experience building, configuring, integrating, or troubleshooting HIL test benches.
• Strong understanding of automotive electrical and electronic systems.
• Experience working with ECUs, sensors, actuators, I/O systems, and test equipment.
• Strong knowledge of automotive communication protocols, particularly CAN/CAN FD and LIN.
• Ability to read and understand electrical schematics, wiring diagrams, ECU pinouts, and connector documentation.
• Experience with electrical wiring, harnesses, connectors, breakout boxes, and test interfaces.
• Understanding of ECU power supply, grounding, signal conditioning, and electrical troubleshooting.
• Strong hands-on troubleshooting and problem-solving skills.

Preferred Qualifications

• Experience with HIL platforms such as dSPACE, Vector, NI, ETAS, or Speedgoat.
• Experience with dSPACE SCALEXIO / MicroAutoBox or similar real-time simulation platforms.
• Experience with Vector CANoe/CANalyzer.
• Experience with MATLAB/Simulink and real-time simulation.
• Experience configuring HIL I/O and signal mapping.
• Knowledge of CAN, CAN FD, LIN, FlexRay, Automotive Ethernet, UDS, and diagnostics.
• Experience with ECU flashing, diagnostics, and communication testing.Experience with automotive network databases such as DBC files.
