Lead Systems Engineer

Lead Systems Engineer - Battery Energy Storage Systems

Energy should be free. We're building the proof.

While the industry scraps millions of EV batteries with decades of life left, Moment Energy repurposes them into advanced BESS — delivering 5x the energy density, fully certified, at real-world scale. We're the only company proving second-life batteries can be safe and scalable, and we did it by engineering the solution nobody thought possible.

The role

We're looking for a Lead Systems Engineer to own the architecture and technical backbone of our BESS platform — bridging electrical, mechanical, software, battery, and controls into one cohesive product. You'll translate customer needs into certifiable requirements, own traceability from spec through validation, and lead the multidisciplinary problem-solving that makes complex hardware actually ship.

You'll be a strong fit if you have:

• 6+ years in systems engineering, systems integration, or multidisciplinary product development
• A track record architecting and integrating complex electrical/software/hardware products from concept to production
• Startup or high-growth experience — comfortable owning ambiguity and moving fast
• Strong grasp of embedded systems, hardware/software interfaces, and system-level V&V
• Bonus: lithium-ion battery experience, or familiarity with UL1973/UL9540/UL9540A

Why Moment Energy

• Build and scale a category-defining product from the ground up, with direct, visible impact
• Work shoulder-to-shoulder with founders on a genuine engineering-first mission
• Equity, strong benefits, and a culture that celebrates wins as a team
