OBD Engineer

Job Title: OBD Performance Tuning Engineer

Location: Columbus, IN

We are looking for analytically oriented engineers to work on performance tuning of diesel engine/aftertreatment diagnostics for state-of-the-art technology.

• Lead current product improvement investigations and projects that involve aftertreatment performance, emissions, on-board diagnostics (OBD), calibration, and/or control system software changes along with hardware interaction.
• Use Matlab & Simulink, simulation, and data analysis for diagnostic and feature calibration tuning.
• Features will be tuned to meet the ACI (Aftertreatment Component Integration) team Feature Review requirements.
• Own FIRG (Failure Incident Reporting Group) issues related to owned diagnostics.
• Follow the 7-Step problem‑solving process:
  Identify the Problem, Identify and Rank Possible Causes, Take Short‑Term Action, Determine Failure Cause(s), Select and Verify the Solution, Implement Permanent Solution, and Monitor/Prevent Recurrence.
• Utilize Matlab & Simulink to understand and tune diagnostic features for aftertreatment sensors and actuators.
• Understand Simulink controls logic.
• Have in‑depth understanding of OBD 3‑step review progress and adhere to that process.
• Have calibration tuning experience for aftertreatment controls and drive each calibration through the maturity process.
• Perform truck testing with engineering calibration tool logging and data analysis.
• Analyze truck data (plots, presentation for design review).
• Present review material in the respective forums in a logical way.
• Analyze aftertreatment performance data.
• Create software change requests for diagnostics if needed (e.g., new architecture causing new inputs to diagnostics thus requiring a software change).

• College/University degree required.
• At least 5 years of relevant work history.
• Strong technical, analytical, critical‑thinking, and leadership skills, and thrive in a dynamic, cross‑functional, team‑based work environment.
