Senior Systems Integration Engineer, Battery Energy Storage System

Responsibilities

• Own system requirements and interface definition from concept through launch to ensure the product performs as intended in the customer application.
• Define and maintain key product interfaces across mechanical, thermal, fluid, electrical, and communication systems.
• Evaluate product performance against requirements using analysis, modeling, and development testing.
• Drive technical tradeoff studies and engineering decisions across subsystems, including cells, modules, structures, thermal management, sensing, bussing, electronics, controls, and power conversion interfaces.
• Work closely with cross-functional partners across systems, manufacturing, validation, supply chain, quality, controls, power electronics, and program management to deliver launch‑ready products.
• Understand applicable codes, standards, regulations, and certification requirements, and ensure requirements and designs align accordingly.
• Guide designs through development gates with strong technical rigor and clear evidence that requirements have been achieved.
• Identify system‑level technical risks early, develop mitigation plans, and lead issue resolution to keep programs on track.
• Benchmark BESS products and relevant adjacent industries to identify opportunities in architecture, technology, and development approach.
• Help define and improve BESS engineering processes, tools, standards, and templates to support future program growth.
• Contribute as a technical leader on an evolving team where speed, sound judgment, and hands‑on problem‑solving matter.

• Proven success leading the technical development of battery systems or closely related electrified products.
• Demonstrated ability to build and manage system requirements and interface definitions from the ground up.
• Strong understanding of BESS subsystems, including cells, modules, structures, thermal management, sensing, bussing, battery management systems, controls, power conversion interfaces, and safety systems.
• Experience evaluating product performance through analysis, modeling, and development testing to support technical decision‑making.
• Experience analyzing high‑voltage electrical systems.
• Ability to lead through influence across cross‑functional teams and align stakeholders around technical direction.
• Strong communication skills with the ability to distill complex technical topics for leadership and cross‑functional decision‑making.
• Demonstrated data‑driven decision‑making grounded in first principles.
• Bachelor of Science in Engineering.
• 5+ years of product engineering experience.
