Description
Senior Systems Integration Engineer, Battery Energy Storage System (BESS)
The Team
The Energy Storage Engineering organization at GM is focused on extending the company's battery and systems expertise to stationary energy storage applications. The work sits at the intersection of advanced technology, system design, and new market opportunities. For candidates who are energized by early-stage innovation and visible impact, this team offers the chance to tackle complex engineering challenges, influence foundational decisions, and help define a growing area of the business.
The Role
The Senior Battery Energy Storage System (BESS) Systems Integration Engineer will lead system definition and integration from concept through launch. This is a highly visible role for an engineer who enjoys connecting complex technical work across functions, shaping system architecture, and ensuring integrated products are ready for real-world applications.
In this position, you will own system requirements and key interfaces, drive cross-functional alignment, and help translate product needs into robust, launch-ready solutions. You will play a key role in ensuring products deliver against performance, cost, safety, reliability, manufacturability, and timing targets while helping build the foundation for GM's growing battery energy storage portfolio.
What You'll Do

• 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.
