As a Senior Systems Engineer, you will play a critical role in bringing our multi-day energy storage systems from pilot stages to full-scale commercial utility deployment. You will own the technical definition, architectural integration, and system-level performance trade-offs of our 100-hour iron-air battery systems, resolving complex multi-variable issues across electrical, mechanical, and electrochemical boundaries. By collaborating closely with cross-functional design, software, and validation teams, you will establish the systems-level design methodologies and verification procedures required to ensure the ultimate safety, durability, and commercial readiness of our technology. Ultimately, your technical leadership and system-level stewardship will directly enable the delivery of highly predictable, resilient energy storage systems that ensure long-term grid stability and continuous power delivery.
