About the role

Position Summary

We are seeking a Diesel Fuel Systems Calibration Engineer to support the development, calibration, and validation of diesel fuel-system control functions. This entry-level position is well suited for a recent engineering graduate with relevant hands-on experience gained through internships, co-ops, university research, or student vehicle programs.

The ideal candidate has a strong foundation in engine systems, controls, and system-level engineering, combined with an analytical mindset and the ability to use modern engineering tools to solve calibration challenges.

The work

Key Responsibilities

• Develop, optimize, and validate diesel fuel-system control parameters to meet engineering targets for emissions, fuel consumption, performance, drivability, diagnostics, and robustness.
• Perform calibration and validation using engine and chassis dynamometers, test vehicles, test tracks, and open-road testing.
• Calibrate and evaluate fuel-system functions including rail-pressure control, injection quantity, injection timing, multiple-injection strategies, and diagnostic functions.
• Analyze interactions between ECU software and controls, calibration parameters, sensors, actuators, fuel-system components, and engine behavior.
• Plan and execute calibration tests, analyze measurement data, evaluate results against engineering targets, and recommend calibration changes.
• Utilize and support the development of advanced calibration and data-acquisition tools to support data analysis, model-based calibration, optimization, and automation.
• Perform system-level troubleshooting and root-cause analysis of fuel-system, controls, calibration, and vehicle performance issues.
• Evaluate and present engine, powertrain, and vehicle test results and communicate technical conclusions to engineering teams and customers.
• Collaborate with controls, systems, software, hardware, and test engineers to resolve technical issues and achieve project targets.
• Participate in local and international calibration networks to exchange technical knowledge and stay current with control-system and calibration developments.
• Support vehicle validation programs, including winter, summer, and altitude testing, with travel of up to 12 weeks per year.
• Bachelor's degree in Mechanical Engineering, Electrical Engineering, Automotive Engineering, Mechatronics, or a closely related engineering discipline.
• 1-3 years of experience with engine controls, powertrain systems, fuel systems, or vehicle technologies through an internship, co-op, professional experience, university research, Formula SAE, EcoCAR, or a similar vehicle program.
• Fundamental understanding of internal combustion engines, control systems, sensors, actuators, and feedback control.
• Strong system-level problem-solving and analytical skills.
• Experience with engineering data acquisition, analysis, and modeling tools such as MATLAB/Simulink, ETAS tools, or comparable engineering environments.
• Experience using Python as an engineering analysis or automation tool.
• Exposure to AI or machine-learning methods applied to engineering problems or engineering data.
• Strong technical communication and teamwork skills.
• Valid driver's license and willingness and ability to travel up to 12 weeks per year in support of vehicle testing and validation.
