Responsibilities

Analyzing High Voltage (400+VDC, HV) and Low Voltage (<56 VDC, LV) system requirements and developing software control architectures for EV systems, including traction inverter control, battery management, thermal management, auxiliary systems, and vehicle-level energy management.
Designing control architectures for operating bidirectional power conversion systems — onboard chargers (OBC), traction inverters, DC-DC converters, and vehicle-to-grid (V2G) interfaces — covering AC-DC and DC-AC topologies.
Developing state machines, protection logic, fault management, and supervisory control strategies for HV systems, including HV-LV domain integration, auxiliary bus management, and isolation monitoring.
Modeling and simulating control systems using MATLAB/Simulink and related toolchains (dSPACE, Embedded Coder) to predict behavior and optimize performance.
Creating detailed design documentation for HV software control algorithms, logic, and architecture decisions.
Programming control logic in C/C++ and model-based design environments; familiarity with industrial automation languages (ladder logic, structured text, function block diagrams) a plus.
Programming networking systems via communication protocols (CAN/J1939, Ethernet/IP, Modbus, UDP), and system interfaces (GUI’s).
Working closely with a software engineering team as a technical peer and subject matter expert, contributing to architecture decisions, design reviews, and development best practices.
Conducting rigorous testing of HV control software in simulated environments (HIL/SIL) and on physical systems to ensure functionality, reliability, and safety compliance.
Identifying and resolving software defects and issues related to HV control system behavior.
Creating test plans and procedures to validate system performance against defined criteria, including applicable standards (ISO 26262 ASIL, IEC 61508 SIL, MIL-STD as applicable).
Demonstrating ability and willingness to be hands-on through the full testing and troubleshooting process on physical HV systems.
Collaborating with hardware engineers to integrate controls software with HV/LV electrical components and power electronics hardware, ensuring seamless operation across the full system.
Coordinating with project teams to ensure proper system integration and communication between control elements across EV and defense platforms.
Engaging with defense customers and program stakeholders to support SOW interpretation, CDRLs, and program milestone reviews.
Ensuring designs comply with applicable MIL-STD requirements (MIL-STD-1275, MIL-STD-704, MIL-STD-461) and functional safety standards as required.
Providing technical support for deployed EV and microgrid control systems, including troubleshooting HV system issues and implementing software updates.
Maintaining system documentation and updating control logic as needed to adapt to changing program requirements or field findings.
