Automotive MCU Hardware Test Engineer

General Motors; Warren (MI); Hybrid; USD 110,000 - 140,000; Full time

Job summary

General Motors is seeking a Hardware Test Engineer – MCU to define and execute hardware test strategies for MCU solutions across EVKs, reference boards, and ECUs. You will bring‑up MCU boards, create test plans, and develop automated tests using Python/C/C++ to ensure functional, performance, and reliability targets are met from early samples to production.

You will work closely with MCU hardware design, ECU hardware, and software teams, using oscilloscopes, logic analyzers, and protocol

Qualifications

• Bachelor’s degree in electrical/computer engineering or related field.
• 4+ years in hardware validation/test engineering for complex digital systems.
• Strong MCU subsystems and IP blocks understanding (CPU cores, peripherals, automotive networking).
• Hands-on experience bringing up/testing complex digital boards with power sequencing.
• Experience creating and executing structured hardware test plans with traceability.
• Proficiency with lab equipment (scopes, analyzers, probes) and measurement tools.
• Experience debugging automotive interfaces (CAN‑FD, LIN, Ethernet) and memory interfaces.
• Experience developing automated hardware tests and data collection scripts (Python, C/C++).
• Strong analytical and collaboration skills; able to work across teams.
• Ability to manage multiple test efforts in parallel.

Responsibilities

• Define end-to-end hardware test strategies for MCUs and related components.
• Plan and execute MCU and board-level electrical characterization across PVT corners.
• Develop automated test frameworks and scripts to improve coverage and efficiency.
• Create test content for MCU subsystems and interfaces (CAN, LIN, Ethernet, SPI, I2C, UART).
• Use lab equipment to characterize signals, validate timing, and root-cause issues.
• Collaborate with MCU design, ECU hardware, and software teams to map requirements to tests.
• Develop reusable test procedures and checklists for multiple programs.
• Support environmental testing and diagnostics for MCU functionality.
• Mentor junior engineers on test methods and lab best practices.
