Test Systems Engineer at Intrepid Control Systems, Inc – Troy, Michigan

Role Overview

The Test Systems Engineer is responsible for developing end-to-end manufacturing test systems across the full product lifecycle. This role contributes to Design for Testability (DFT) by partnering with hardware and software teams to ensure efficient, scalable, and reliable testing solutions.

This position requires strong, hands-on software development experience, including writing, debugging, and maintaining production-quality code.

The position involves architecting physical test environments and developing high-performance software for both device-level control and enterprise-level data management.

Responsibilities

• Design and develop End-of-Line (EOL) test systems using Python and Rust, interfacing with electronic devices via CAN, LIN, UART, and Ethernet
• Write, debug, and maintain production-quality code across multiple languages (primarily Python, with exposure to C/C++ and Rust)
• Collaborate with hardware engineering teams to ensure PCBA testability, including performing schematic reviews in Altium and troubleshooting circuit-level issues during system bring-up
• Develop modern, responsive user interfaces using PySide6 (Qt for Python) to support manufacturing technicians with intuitive tools
• Design, build, and maintain backend systems using Rust (Axum framework) and REST APIs to ensure data integrity and traceability of test results
• Debug and support core libraries written in C++ as needed, optimizing system performance and reliability
• Provide production support by troubleshooting End-of-Line software issues, documenting processes, and improving manufacturing station uptime

• Strong hands-on coding experience, including developing and maintaining production-level software (not limited to scripting)
• Python (advanced proficiency required)
• C / C++
• Rust (strongly preferred)
• HTML, CSS, JavaScript
• Schematic proficiency (Altium preferred)
• Experience with communication protocols (CAN, LIN, UART, Ethernet)
• Basic circuit analysis and debugging
• VS Code
• Git / GitLab
• Vehicle Spy 3 (preferred)
• Axum (Rust)
• Dioxus / Tauri
• Qt (PySide6)
• OAuth, REST APIs, JSON integration

• Experience in manufacturing or production test environments
• Familiarity with automated test systems and hardware/software integration
• Strong troubleshooting and cross-functional problem-solving skills
