Job Title: Software Test Engineer

We are seeking a Software Innovation Lab Engineer to support an advanced technology integration and testing environment. This individual will be responsible for designing, maintaining, and troubleshooting lab-based integration and test systems. The engineer will play a key role in supporting hardware-in-the-loop (HIL) systems, simulation tools, and electro-mechanical test setups. This position requires strong hands‑on technical skills, particularly in system integration, networking, and hardware/software troubleshooting. The ideal candidate thrives in a lab environment, enjoys solving complex system‑level issues, and can effectively communicate across cross‑functional engineering teams.

Responsibilities

• Design, maintain, and troubleshoot lab‑based integration and test systems.
• Support hardware-in-the-loop (HIL) systems, simulation tools, and electro‑mechanical test setups.
• Work collaboratively across cross‑functional engineering teams to solve complex system‑level issues.
• Perform hands‑on troubleshooting of hardware and software systems.

Essential Skills

• Proficiency with Linux and Windows systems, including terminal usage, shell scripting, and PowerShell.
• Ability to interpret and analyze system logs using tools like Windows Event Viewer, syslog, and dmesg.
