Job DescriptionSenior Emissions Compliance Test Engineer

Full-Time Direct Placement

From the first spark in the test cell to the final compliance report, you’ll own the journey. Join a well-established leader in emissions technologies and regulatory product approvals in a hands-on role where engines, data, and customer trust come together. If you enjoy taking projects from kickoff to delivery and getting your hands on hardware, this role is for you.

A Day in the Life

You arrive to a prepared test plan, validate instrument calibrations, and lead a CFR-compliant emissions run. Midday, you brief the customer on interim findings as the primary point of contact. In the afternoon, you troubleshoot a stubborn sensor drift, refine your data quality control checks, and mentor a junior engineer on best practices for test equipment calibration and safe engine setup. By day’s end, you’ve advanced performance testing, captured clean datasets, and charted tomorrow’s improvements.

• Plan and execute CFR-compliant emissions and engine performance testing
• Author test plans and manage data quality control, analysis, and reporting
• Serve as the primary customer contact throughout test programs
• Troubleshoot engines, vehicles, and lab equipment to resolve issues quickly
• Mentor and train junior engineers and test-cell technicians
• Oversee test equipment calibration and modify test instrumentation as needed

What You Bring

• Bachelor’s degree in Engineering (Master’s preferred)
• 3–5+ years of relevant engineering experience
• Deep engine knowledge and mechanical aptitude
• Emissions or engine testing experience (CFR 1065/1066/86 a strong plus)
• Familiarity with Horiba MEXA analyzers (training provided)
• Exceptional analytical, troubleshooting, and customer communication skills
