This is a hybrid position requiring 4 days per week in the office. Agency employees are required to be onsite from the first day.

• Plan, execute, and support vehicle, powertrain dynamometer, and/or engine dynamometer testing at internal facilities and external vendor locations.
• Support testing and validation of low‑emission technologies against future emissions standards, including ACCII Stand Alone US06.
• Identify potential calibration concerns and issues encountered during testing and communicate findings to technical specialists for resolution and guidance.
• Perform post‑processing of test data files using supplied or alternative vendor tools.
• Extract and analyze key statistics for emissions compliance and calibration assessment.
• Conduct detailed analysis of emissions test data and provide data‑driven recommendations to optimize calibrations and address issues.
• Summarize test findings, data analysis results, and recommended actions through clear technical presentations.
• Use data visualization methods such as boxplots and modal cumulative plots to communicate technical information.
• Track and maintain accurate records of test vehicle status, including fuel types, hardware configurations, calibration levels, and relevant modifications.
• Participate in test planning to ensure testing aligns with program goals and timelines.
• Prepare and submit Test Requests (TRs) on a weekly basis to facilitate required testing activities.
• Develop, optimize, and validate full‑cycle emissions calibrations, including cold start, warm‑up, and hot stabilized conditions.
• Support calibration activities targeting SULEV
  30, ACCII, and Tier 4 gaseous and particulate matter tailpipe emissions standards.
• Develop data acquisition lists and record data using appropriate acquisition software.
• Verify data integrity, including sample rate, alignment, and reasonable parameter values.
• Develop naming conventions and data storage systems that allow test files to be easily located and accessed.
• Evaluate test data and develop changes to engine emissions calibration to reduce tailpipe emissions and optimize aftertreatment performance.
• Execute predefined test plans and apply structured problem‑solving processes to resolve technical issues.
• Prepare technical documentation, spreadsheets, and presentations to communicate testing, findings, and next steps.

• Bachelor's degree in Chemical Engineering or Mechanical Engineering.
• 3+ years of experience in emissions and emissions testing.
• 3+ years demonstrating a fundamental understanding of internal combustion engine function.
• Solid understanding of emissions regulations, certification processes, and technologies used to reduce emissions.
• Advanced problem‑solving skills.
