Job Description About GM

There's never been a more exciting time to work for General Motors. To achieve our vision of a world with Zero Crashes, Zero Emissions and Zero Congestion, we need people who are passionate about creating safer, better, and more sustainable ways for people to move. This bold vision won’t happen overnight, but just as we transformed how the world moved in the last century, we are committed to transforming how we move today and in the future. Our culture is focused on building inclusive teams, where differences and unique perspectives are embraced so you can contribute to your fullest potential as you pursue your career.

The Role

We are seeking a high‑performing Hardware Development Engineer to plan, develop, and execute fuel injector component and subsystem tests in a world‑class development facility. Responsibilities include hands‑on test bench work, data analysis, calibration support, and driving test efficiency through data reduction and virtualization of lab activities. This assignment requires creativity, initiative, and independent judgment, as well as effective cross‑organizational teamwork.

What You’ll Do

• Test & Bench Ownership: Execute fuel injector development and validation testing across multiple engine programs.
• Develop, implement, and execute first‑time capable tests for hardware development and validation on fuel injector benches.
• Lead diagnosis and resolution of issues that occur during test setup, execution, and post‑test investigations.
• Track and report test status, issues, and risks to support program milestones and decision making.
• Ensure all testing is conducted in accordance with GM safety, quality, and procedural standards.
• Data, Tools & Virtualization: Create, maintain, and utilize post‑processing tools (e.g., MATLAB, Python) to assure data quality and improve test efficiency.
• Analyze data to optimize test plans, reduce test time, and support virtual model development and correlation.
• Identify and implement data reduction opportunities, including standardization of data sets and automation of routine analysis tasks.
• Contribute to the migration of lab‑based activities to virtual methods, partnering with analysis and virtualization teams.
• Collaboration & Continuous Improvement: Collaborate with facilities, technical specialists, calibration teams, hardware release engineers, and other stakeholders to improve process and test efficiency.
• Participate in the pursuit of test reduction and elimination, working with design, analysis, and program teams to identify where physical testing can be streamlined, replaced, or virtualized.
• Support continuous improvement of standard work, procedures, and documentation for fuel injector bench testing.
• Leadership & Mentoring: Train, mentor, and develop new engineers and co‑ops/rotators on bench operation, safety, and standard work.
• Provide technical guidance on fuel injector function, test methods, and data interpretation to peers and partners.

Education & Training

BS in Mechanical Engineering, Aerospace Engineering, Electrical Engineering, Chemical Engineering, Computer Science, Physics, or a related engineering discipline.

Required Skills & Experience

• Minimum 2 years of experience in automotive engineering with engine knowledge.
• Demonstrated drive for results in a laboratory or development environment.
• Strong planning and problem‑solving skills, including the ability to manage multiple test activities in parallel.
• Strong oral and written communication skills.
• High level of interpersonal skills to work effectively with others, build peer relationships, and work independently with minimal direction.
• Proven ability to prioritize work and resources, balancing urgent program needs with long‑term improvements.
• Proficient with computer and data acquisition systems used in test environments.
• Experience in data analysis to optimize testing, assess hardware performance, or support model correlation.
• Experience using and creating MATLAB and Python scripts for data analysis and post‑processing.

Preferred Skills & Experience

• Experience with ETAS INCA software.
• Exposure to engine calibration in test cell and/or vehicle environments.
• 4+ years of experience in automotive engineering with engine development or testing.
• Hands‑on experience with test bench setup and testing.
• Experience with engine function, architecture, and subsystems, especially the fuel injection system.
• Hands‑on experience with fuel injection system testing (flow, spray characterization, durability, etc.).

Work Location & Model

This role is expected to be lab‑based/hybrid, with significant time spent on‑site in the Pontiac test facility supporting hands‑on bench activities. Specific onsite expectations and hybrid details will be defined by the hiring manager based on business needs. GM does not provide immigration‑related sponsorship for this role. Do not apply for this role if you will need GM immigration sponsorship now or in the future. This includes direct company sponsorship, entry of GM as the immigration employer of record on a government form, and any work authorization requiring a written submission or other immigration support from the company (e.g., H1‑B, OPT, STEM OPT, CPT, TN, J‑1, etc). This role is categorized as hybrid. This means the selected candidate is expected to report to a specific location at least 3 times a week {or other frequency dictated by their manager}. This job is not eligible for relocation benefits. Any relocation costs would be the responsibility of the selected candidate.
