About The Position

A Diagnostic and ETRS Calibration Engineer plans and executes testing activities to develop and calibrate transmission diagnostic and Electronic Transmission Range Selection (ETRS) features, ensuring compliance with OBD regulations and alignment with system safety requirements. This role operates within a collaborative team environment while serving as a key contributor to all transmission controls programs. The Calibration Engineer, Transmission Diagnostic & ETRS is responsible for validating ETRS systems, diagnostic algorithms, and associated calibrations through a combination of test benches, dynamometers, vehicle testing, and system simulation methods. Additionally, this role involves developing, maintaining, and executing comprehensive test plans to ensure proper integration of diagnostic algorithms within transmission and vehicle embedded systems. Key deliverables include calibration guides, detailed test plans, thorough documentation of test results, production-released diagnostic calibrations, and certification documentation. Calibration engineers are engaged throughout the full product lifecycle—from early development and validation to product launch and post-production support. This position is well-suited for individuals who are innovative, detail-oriented, and passionate about emissions control systems and vehicle safety.

Requirements

• Bachelor of Science in Mechanical Engineering, Electrical Engineering, Computer Engineering, Computer Science, or a related technical field.
• 2+ years of automotive engineering experience
• 2+ years of hands-on experience in calibration, diagnostics, or transmission/powertrain development or similar
• Working knowledge of vehicle systems, embedded controls, or diagnostics
• Exposure to OBDII regulations (CARB familiarity is a plus)
• Experience with calibration and data tools (e.g., INCA, CANalyzer, vSpy, or similar)
• Strong problem-solving and analytical skills
• Ability to work effectively in a team environment with shifting priorities
• Strong communication skills (written and verbal)
• Valid driver’s license and willingness to support vehicle testing activities
• Ability to travel occasionally (<5%)

Nice To Haves

• Master of Science degree in Mechanical Engineering or Electrical Engineering
• Exposure to transmission systems, ETRS, or broader powertrain operational principles.

• Transmission operational knowledge
• Experience with HIL, system simulation, dyno testing, or in-vehicle development tools and methods.
• Familiar with Python, C, or automation tools used for test execution or data processing.
• Experience with Serial Data busses, including CAN, GMLAN, LIN
• DFSS Black Belt certification

Responsibilities

• Develop calibrations of transmission diagnostic and ETRS features to meet performance, compliance, and customer expectations.
• Plan and Execute test activities using simulation, bench testing, HIL, dynamometer, and in-vehicle methods.
• Analyze test data, document results in engineering reports, and help investigate test non-conformities and issue root causes.
• Help develop and maintain test plans, calibration procedures, and calibration guides to support robust feature development and validation.
• Work with algorithm, controls, and system safety engineers to support new function development, issue resolution, and test procedure improvements.
• Support vehicle development, durability, warranty, and problem-resolution activities for assigned ETRS and transmission programs.
• Participate in peer reviews, technical reviews, and program milestone discussions while communicating status and key findings to stakeholders.
• Contribute to tool, process, or data-handling improvements that reduce manual effort and improve test efficiency.
