Senior Hardware Test Engineer – MCU

Work Arrangement: Hybrid: This role is categorized as hybrid. This means the successful candidate is expected to report to Warren, MI three times per week, at minimum. The Role General Motors is at the forefront of the transformation of automotive with the electrification of our portfolio and the development of leading-edge central compute, connectivity, and autonomous capabilities. Our Semiconductor Engineering team is a dynamic, high‑energy, and innovative group focused on design and commercialization of leading‑edge silicon enabling the future of GM’s Software Defined Vehicle (SDV) platforms – central compute units, connectivity modules, and other controllers. We are seeking a highly skilled and driven Senior Hardware Test Engineer – MCU to join our Semiconductor Center of Excellence. This pivotal role will lead the definition, development, and execution of hardware test strategies for state‑of‑the‑art Microcontroller (MCU) solutions used in next‑generation automotive electronics platforms. You will be responsible for MCU and MCU‑centric ECU board bring‑up, test plan creation, automated test development, and systematic debug to ensure our silicon and hardware platforms meet functional, performance, and reliability goals from early samples through production. What You’ll Do: Define hardware test strategies and structured bring‑up plans for MCUs and related components across EVKs, reference boards, and ECUs Lead board bring‑up activities, including power‑on sequencing, clock/reset validation, peripheral bring‑up, and regression testing Plan and execute electrical characterization testing, including power, leakage, timing margins, and I/O threshold validation across operating conditions Develop and maintain automated test frameworks and scripts using Python, C/C++, or similar tools Create test content for key MCU subsystems and interfaces, including CAN, LIN, Ethernet, SPI, I2C, UART, ADC/DAC, PWM/timers, memory, and security features Use lab equipment to validate signals, timing, and performance, and to debug hardware issues Partner with hardware and software teams to convert system requirements into test cases and coverage metrics Develop reusable test procedures, documentation, and checklists across programs Support DV/PV and environmental testing with functional monitoring, lab setups, and diagnostics Mentor junior engineers on test methods, lab practices, and debug techniques Required Qualifications: Bachelor’s degree in electrical engineering, computer engineering, or a related field. 7+ years of experience in hardware validation or test engineering for complex digital systems, MCUs, or high‑integration ECUs. Strong understanding of MCU subsystems and IP blocks (CPU cores including lockstep, embedded flash, peripherals, automotive networking, power management, and safety mechanisms) from a validation and debug perspective. Proven hands‑on experience bringing up and testing complex digital boards, including power sequencing, clock/reset validation, and interface bring‑up. Demonstrated experience creating and executing structured hardware test plans, including definition of objectives, coverage, pass/fail criteria, and traceability to requirements. Proficiency with lab equipment such as oscilloscopes, logic analyzers, protocol analyzers, power supplies, electronic loads, and precision power / current measurement tools. Hands‑on experience with MCU and board‑level electrical characterization (voltage/current limits, static and dynamic power, leakage, timing margins, and I/O thresholds) across PVT corners, including correlation to specifications and models. Practical experience debugging automotive serial interfaces (CAN‑FD, LIN, Ethernet, SPI) and/or higher‑speed memory interfaces, including interpretation of signal integrity and timing issues. Experience developing automated hardware tests and data collection scripts (Python, C/C++, or similar scripting environments). Strong analytical and problem‑solving skills, with the ability to isolate root causes across silicon, board, and software boundaries. Demonstrated ability to manage multiple test efforts in parallel, including planning, execution, and reporting. What Can Give You a Competitive Edge (Preferred Qualifications): Master’s degree in electrical engineering, computer engineering, or a related field Experience validating automotive or other safety‑critical MCUs and ECUs Experience with environmental, reliability, and margin testing Experience with test automation frameworks, CI pipelines, and lab management tools Strong collaboration skills and ability to work across teams Benefits: GM offers a variety of health and wellbeing benefit programs.
