About The Position

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 and autonomous capabilities. Our Semiconductor Engineering team is a dynamic, high-energy, and innovative group focused on design and commercialization of leading-edge hardware enabling the future of GM’s vehicle architecture. We are seeking a Senior Hardware Engineer with a strong focus on electrical testing and validation to lead the test strategy, test case definition, and lab execution for wired connectivity technology (e.g., automotive Ethernet, infotainment SerDes) across ECUs and semiconductor devices. This position is on the Network Technology and Design team and is dependent on building strong partnerships with both internal ECU design teams and external semiconductor partners.

Requirements

• BS in Electrical Engineering / Electronics / Computer Science (or equivalent).
• 5+ years of engineering experience at an OEM, semiconductor supplier, or Tier 1 ECU supplier.
• 3+ years of hands-on experience in electronic hardware design and/or electrical validation and testing for complex ECUs, network interfaces, or similar systems.
• Working knowledge of automotive electronic hardware and automotive software architecture (ECUs, networks, diagnostics, and integration flows).
• Strong proficiency in circuit fundamentals, ability to interpret schematics and PCB layouts, and understanding of how design choices impact testability and lab behavior.
• Demonstrated experience with lab equipment such as power supplies, high‑bandwidth oscilloscopes, signal generators, electronic loads, protocol analyzers, and multimeters.
• Experience planning and executing structured hardware validation, including test procedure development, data collection, and documentation.
• Experience with requirements and/or test management tools (e.g., DOORS, Jama, Polarion, or equivalent) and maintaining traceability from requirements to test cases and results.
• Familiarity with hardware design and analysis tools such as Mentor Graphics Xpedition and ORCAD (or equivalent) for reviewing designs and informing test strategies.
• Exceptional collaboration and teamwork skills; demonstrated ability to work across functional and organizational boundaries (hardware, software, systems, suppliers).
• Proven experience leading projects to completion, including coordination of lab work, driving closure of defects, and achieving test sign-off.
• Strong problem-solving skills and demonstrated ability to learn quickly in a fast-paced, technically complex environment.

Nice To Haves

• Master’s degree in Electrical Engineering or related field.
• Industry knowledge of semiconductor design and application, especially for network PHYs, switches, and related mixed-signal devices.
• Hands-on experience with automotive Ethernet (10BASE‑T1S, 100BASE‑T1, 1000BASE‑T1) and/or SerDes electrical test methods, standards, and compliance / interoperability testing.
• Experience with automated test development (e.g., Python, LabVIEW, or similar) and building reusable test scripts or frameworks.
• Familiarity with SI/PI tools and correlating simulation results with lab measurements.
• Experience influencing lab capability roadmaps, capital planning, and deployment of new test methodologies or instrumentation.

Responsibilities

• Own the end-to-end hardware electrical test strategy for network technologies, from requirements analysis through coverage closure and sign-off.
• Define and maintain test cases and test procedures for wired connectivity (e.g., automotive Ethernet), ensuring traceability to system, hardware, and safety requirements.
• Establish and own requirements linking between system / hardware requirements and verification artifacts (test cases, test results, analyses), including coverage metrics and reporting.
• Drive test environment capability enhancements: Define and evolve bench setups, fixtures, test boards, and harnesses to support new network features and operating corners.
• Identify gaps in lab capabilities (e.g., bandwidth, jitter, protocol decoding, automation) and lead upgrades in collaboration with lab and capital planning.
• Standardize test environments and best practices across programs and suppliers.
• Lead bench test execution throughout the development lifecycle, including bring-up, characterization, margining, regression, and release testing.
• Perform detailed hardware analysis in support of testing, including worst-case analysis, signal integrity (SI), and power integrity (PI), to define appropriate test coverage and limits.
• Troubleshoot test failures and anomalous behavior, perform root cause analysis, and drive corrective actions with ECU and semiconductor design teams.
• Develop and maintain test specifications and verification plans that clearly define scope, pass/fail criteria, and acceptance limits for each test item.
• Collaborate with cross-functional teams in software, mechanical, systems, safety, and manufacturing to ensure that test coverage aligns to program needs and that test findings are rapidly integrated into designs.
• Interface with semiconductor partners and Tier 1s to align on device- and ECU-level test requirements, share lab results, and ensure issues are resolved in silicon and hardware revisions.
• Provide clear, data-driven test reports and technical summaries to leadership and program teams, including risk assessments and release recommendations.
• Support and lead design and test reviews, presenting coverage status, key test results, and open issues.
• Establish and continuously improve domain expertise in network semiconductor and ECU product lines within scope of responsibility, especially in the context of electrical validation and compliance testing.
• Contribute to and help manage technology and test methodology roadmaps in close collaboration with industry leaders, aligning lab capabilities and test strategies with future architectures.

Benefits

• GM offers a variety of health and wellbeing benefit programs. Benefit options include medical, dental, vision, Health Savings Account, Flexible Spending Accounts, retirement savings plan, sickness and accident benefits, life insurance, paid vacation & holidays, tuition assistance programs, employee assistance program, GM vehicle discounts and more.
