Overview
Navitas Systems is seeking a Principal Battery Management System (BMS) Engineer to provide technical leadership, architectural ownership, and long-term stewardship of advanced BMS solutions for lithium-ion battery products serving military, commercial, and industrial markets.
The Principal BMS Engineer defines technical direction, owns system-level architecture decisions, ensures regulatory and functional safety compliance, and serves as the subject-matter expert across firmware, electronics, algorithms, and system integration.
In this role, you will own and steward multi-generation BMS platforms, define system-level technical direction, and guide cross-functional architectural decisions to ensure BMS solutions are robust, scalable, and aligned with current and future product roadmaps.
Responsibilities
- Serve as technical authority for BMS architecture, including firmware, electronics, sensing, controls, and system integration.
- Define and maintain system-level BMS architecture, design patterns, and technical standards across multiple product lines.
- Lead technical trade studies for safety, performance, cost, manufacturability, and long-term maintainability.
- Establish best practices for embedded firmware architecture, hardware abstraction, diagnostics, and fault handling.
- Provide expert-level guidance on embedded firmware design, real-time systems, and safety-critical software.
- Lead development and review of core BMS algorithms, including SOC, SOH, SOE, cell balancing, protection, diagnostics, and degradation monitoring.
- Own interpretation and application of relevant safety and compliance standards (e.g., UL, IEC, ISO, functional safety guidance) as they relate to BMS design.
- Drive system-level requirements decomposition, traceability, and verification strategy.
- Lead DFMEA, FTA, and system-level risk assessments; ensure mitigation strategies are implemented and verified.
- Guide development of end-of-line test strategies, diagnostic coverage, and service tools.
- Ensure BMS designs are manufacturable, testable, and serviceable at scale.
- Support long-term sustainment, reliability improvements, and continuous improvement initiatives.
- Other duties as assigned by management.
