Responsibilities

Engineer the electrical, data, and safety interfaces that link batteries, PDUs, converters, sensors, and controllers.
Develop interface control documents, power‑flow diagrams, signal lists, and communication maps.
Ensure plug‑and‑play modularity and support evolving system configurations using MOSA principles.
Specify analog/digital signal behavior from filtering and timing to fault responses.
Define and validate communication protocols (CAN, Ethernet, Modbus, proprietary serial).
Engineer safety logic, interlocks, and high‑energy protective behaviors.
Align interface logic with battery, controls, and power electronics teams.
Assess batteries, sensors, controllers, and switching systems for performance and long‑term adaptability.
Lead interface‑focused trade studies centered on safety, reliability, and environmental resilience.
Confirm compliance with electrical, thermal, communication, and EMI/EMC standards.
Build test plans targeting interface integrity, communication performance, and safety logic.
Support system bring‑up with real‑time signal verification and controller integration testing.
Participate in FAT, regression, and fault‑insertion testing to validate system robustness.
Document results and champion interface improvements.
Develop and maintain ICDs, wiring definitions, signal tables, and safety logic documentation.
Manage configuration control across multiple builds and revisions.
Review and refine technical documentation from junior engineers.
Partner with systems, power electronics, controls, and software teams to align requirements.
Serve as the interface SME in design reviews and customer engagements.
Mentor emerging engineers in interface design best practices.
Ensure interface designs meet NFPA 70E, MIL‑STD‑461, IEEE, and project‑specific requirements.
Contribute to hazard analyses and risk mitigation for high‑energy systems.
