Job DescriptionThe RoleGeneral 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 skilled and driven Hardware Test Engineer - MCU to join our Semiconductor Center of Excellence. This role will contribute to 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.
Responsibilities- Define end-to-end hardware test strategies and structured bring-up plans for MCUs and associated components (embedded flash, SRAM, external flash/DRAM where applicable, PMIC, transceivers, watchdog, oscillators) across EVKs, reference boards, and ECUs - including power-on sequencing, clock/reset validation, basic sanity, peripheral bring-up, regression suites, coverage goals, and clear pass/fail criteria.
- Plan and execute MCU and board-level electrical characterization testing (for example voltage/current limits, static and dynamic power, leakage, sleep/wake current, timing margins, and I/O thresholds) across PVT corners and operating modes.
- Design, implement, and maintain automated test frameworks and scripts (for example, Python, C/C++, or similar) to improve coverage, repeatability, and execution efficiency.
- Develop test content and automation for key MCU subsystems and interfaces, such as CAN, LIN, Ethernet, SPI, I2C, UART, embedded flash & SRAM, ADC/DAC, PWM/timers, and HSM/security IP, including margin, and stress testing.
- Use lab equipment (oscilloscopes, logic analyzers, protocol analyzers, power supplies, electronic loads, JTAG tools, etc.) to characterize signals, validate timing and margins, and root-cause hardware issues.
- Partner closely with MCU hardware design engineers, ECU hardware teams, and software teams to translate system requirements into concrete test cases and coverage metrics.
- Develop and maintain reusable test procedures, documentation, and checklists that can be applied across multiple programs and platforms.
- Support DV/PV and component environmental testing by defining hardware functional monitoring, lab setups, and diagnostics required to exercise MCU-level functionality.
- Provide technical mentorship and guidance to junior engineers on test methods, lab best practices, and debug techniques.
Qualifications - Required- Bachelor's degree in electrical engineering, computer engineering, or a related field.
- 4+ 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.
- Exceptional collaboration and teamwork skills; proven ability to work across functional and organizational boundaries.
- Demonstrated ability to manage multiple test efforts in parallel, including planning, execution, and reporting.
Qualifications - Preferred- Master's degree in electrical engineering, computer engineering, or a related field.
- Experience with validation of automotive or other safety-critical MCUs and ECUs.
- Experience defining and executing environmental, reliability, and margin testing (voltage/temperature corners, jitter and eye diagrams, long-duration stress).
- Experience with test automation frameworks, CI pipelines, and lab management tools used to run large-scale automated regressions.
