Job Description

Position Description:

The Advanced Emissions Calibration Engineer is responsible for developing and demonstrating system-level capabilities to achieve future emissions targets (SULEV20, SULEV15, and SULEV10) for gasoline-powered Internal Combustion Engines (ICE), Hybrid (HEV), and Plug-in Hybrid (PHEV) applications. This role bridges the gap between virtual simulation and physical validation, leading the development of calibration strategies that balance stringent regulatory compliance with core vehicle attributes like fuel economy and drivability. The ideal candidate combines high-level analytical strategy with a "hands-on" approach to commissioning and debugging complex prototype propulsion systems.

Skills Required:

Chemical Engineering - Ability to understand and communicate with team regarding exhaust gas chemical reactions
Quality Control - Statistical methods for data analysis
Electrical Engineering - Ability to understand electrical systems and needs for various engine control devices. Understanding of power distribution dn architecture, including 48v system concepts
System Integration - Higer level understanding of vehicle control system and electrical systems and ability to consider balances and tradeoffs for system level attributes and balancing the needs to for the entire vehicle in the context of emissions control
Project Management - Manage multiyear projects for vehicle system design and testing including managing parts procurement, test resource management and timing, and regular status reporting to management
Mechanical Engineering - Understanding of how vehicle engine and powertrains function, from conventional ICE to various hybrid configurations.

Skills Preferred:

Performance Testing - Conduct vehicle level, engine only, and powertrain testing to investigate, develop, and demonstrate emissions compliance with varied aftertreatment systems
Regulatory Affairs - Understanding of current emissions regulations, and familiarity with regulations, and ability to understand and adapt to emerging regulations
powertrain - Understanding of curren powertrain offerings and various hybrid configurations from MHT, to PowerSplit to full EREV. Ability to adapt control strategy and calibration to different operating conditions of each powertrain configuration.
Quality Control
Analytical Chemistry - Understanding of chemical reactions in relation to aftertreatment echaust gas, NOx, HCs, CO, Sulfur, O2, etc.
Leadership - Self-motivated, able to develop a project from concept phase through development through to report out and conclusion phase.
Data Modeling - Experience with data analysis techniques and ability to model trends from large data sets. Use or create models to predict vehicle and emissions attribute performance during experiment definition phases
Environmental Compliance - Understanding of current and proposed future emissions regulations
Project Planning - Manage multiyear projects for vehicle system design and testing including managing parts procurement, test resource management and timing, and regular status reporting to management
MATLAB modeling - Matlab or equivalent (Python etc) to process large data sets and predict performance of engine and aftertreatment components

Education & Experience Required:

Bachelor's degree in Mechanical Engineering, Electrical Engineering, Automotive Engineering, or a related technical field.
5+ years of experience in powertrain calibration, with a specific focus on gasoline emissions and/or electrified propulsion systems (HEV/PHEV).
Technical Tools: Proficiency with industry-standard calibration tools (e.g., ATI Vision, ETAS INCA, or Vector CANape) and CAN communication protocols.
Regulatory Knowledge: Deep understanding of global emissions regulatory requirements and test procedures, specifically SULEV20, SULEV15, and SULEV10 standards.
Hands-on Aptitude: Demonstrated mechanical and electrical (wiring) skills for prototype vehicle/bench setup and hardware-in-the-loop troubleshooting.
Testing Proficiency: Experience with data acquisition (DAQ) systems and various testing environments, including engine/chassis dynamometers.
Data Analysis: Experience in data engineering and statistical validation, with a proven track record of analyzing large-scale datasets to identify statistically significant trends

Education & Experience Preferred:

Advanced Degree: Master's or PhD in Engineering with a focus on Thermal-Fluids, Controls, or Power Electronics.
Exhaust Aftertreatment: Expertise design and validation of exhaust aftertreatment.
Specialized Software: Experience with MATLAB/Simulink and advanced DOE optimization software (e.g., AVL ASCMO, Model-Based Calibration Toolbox).
Hybrid Strategy: Specific experience in developing hybrid energy management strategies and engine start/stop emissions control.
Leadership: Proven ability to lead cross-functional technical reviews and mentor junior calibration engineers.
