Position Overview

We are seeking a highly experienced innovative, detail oriented and self-driven Vehicle Emissions and OBD Fleet Validation Engineer to join our team in Chino, California. In this role you will support the validation of engine management and on-board diagnostics systems for pre-production vehicles that undergo extensive mileage accumulation and emissions durability testing. You will help ensure that our propulsion systems meet demanding emissions standards, operate with high reliability, and deliver exceptional customer satisfaction.

This position offers the opportunity to work directly with prototype vehicles, data intensive development programs, advanced calibration technologies, and cross-functional engineering teams. You will help shape the next generation of internal combustion, hybrid, and electrified propulsion systems through rigorous testing and data-driven insights.

WHAT YOU WILL DO

Key Responsibilities

* Lead comprehensive validation activities for engine management, emissions, and On-Board Diagnostics (OBD) systems utilizing pre-production vehicles deployed in long-term fleet testing programs. Ensure testing is executed in real-world operating conditions to support robustness, durability, and regulatory compliance objectives.

* Set up and configure advanced vehicle instrumentation, including data loggers and sensors, and continuously monitor fleet vehicles to ensure accurate data acquisition, data integrity, and reliable test execution throughout the test lifecycle.

* Lead complex and cross-disciplinary debugging activities involving hardware, embedded software, calibration, and full vehicle systems. Drive root cause identification through systematic investigation and collaboration with internal engineering teams.

* Analyze high-resolution, second-by-second vehicle data captured from data loggers to identify early indicators of component degradation, system malfunctions, calibration deficiencies, or emerging reliability risks before customer impact.

* Plan and conduct emissions testing at defined mileage accumulation intervals to verify emissions system durability, confirm compliance with applicable regulations, and ensure consistency with certification targets.

* Analyze exhaust and evaporative emissions data to determine root causes of failures or performance deviations. Develop and communicate proposed countermeasures and corrective actions to technical counterparts and management.

* Perform advanced data analysis using tools such as MATLAB, Python, or equivalent platforms to extract trends, correlations, and actionable insights that support data-driven engineering decisions.

* Support fleet operation activities including calibration updates, software flashing, diagnostic evaluation, issue triage, and vehicle readiness assessments to ensure continuous fleet availability.

* Investigate high-occurrence and emerging warranty issues through data analysis, vehicle history review, and cross-functional collaboration to support long-term quality improvements.

* Prepare and deliver clear, concise technical summaries, reports, and status updates for engineering leadership and cross-functional stakeholders, translating complex data into actionable conclusions.

* Manage administrative aspects of fleet testing programs, including budget tracking, vehicle utilization, test request planning, schedule management, and milestone documentation.

* Evaluate new technologies, tools, and methodologies that support compliance with evolving emissions and OBD regulations while improving efficiency, accuracy, and development speed.

* Plan, coordinate, and track project activities to ensure on-time delivery, high-quality execution, and alignment with program objectives.

* Travel up to 15% domestically and…
