Job Overview

The Systems Engineering team is seeking an experienced Systems Engineer to own the integration of our Range Extender (internal combustion engine (ICE), generator and inverter) system into our EV architecture.

In this role, you will coordinate the mechanical integration, controls, and regulatory compliance for the Range Extender system. You will not only ensure the engine runs smoothly and charges the high-voltage battery efficiently but also lead the critical pathway to CARB OBD II certification. You will manage a mix of in-house testing and outsourced engineering partners to ensure our vehicles are legal, reliable, and drivable.

What you will do:

• Lead the systems integration of the Range Extender into the vehicle chassis and high-voltage architecture.
• Perform engine and vehicle calibration to balance drivability (NVH), thermal management, fuel efficiency and emissions.
• Define functional requirements for the range extender operation strategy to maintain HV Battery SOC.
• Troubleshoot system integration issues between the ICE, Generator, Inverter, and Vehicle Systems.

• Develop and own the OBD Certification Roadmap to ensure compliance with CARB 1968.2 and EPA requirements.
• Define OBD monitor requirements, P-code logic, freeze frame data, and diagnostic connector specifications.
• Manage the OBD demonstration vehicle testing cycles.

• Act as the technical point of contact for external engineering consultancies and testing laboratories (e.g., emissions dyno labs).

• Create DVP&R (Design Verification Plan and Report) for the range extender system.
• Conduct in-vehicle testing and data logging using industry-standard tools.

Who you are:

• Possess a Bachelor's degree or other relevant educational credential.
• 5+ years of experience in automotive powertrain systems, specifically with internal combustion engines or hybrid architectures.
• Strong working knowledge of CARB OBD II requirements, emissions standards, and the certification lifecycle.
• Hands-on experience with calibration and data acquisition tools (e.g., Vector CANape, CANalyzer and ETAS INCA).
• Ability to understand the interaction between thermal, mechanical, electrical and controls systems.
• Experience with Matlab/Simulink control logic.
• Knowledge of industry standards and best practices related to requirements and testing of automotive systems
• Strong problem-solving skills with the ability to effectively communicate and collaborate within a dynamic team environment
