Senior Cost Accountant

Electra is reinventing ironmaking from the ground up with a breakthrough electrochemical technology that produces high‑purity clean iron and critical co‑minerals. With two operating pilots in Boulder and a new demonstration facility underway in Jefferson County, we’re on track to reach commercial scale by the end of the decade. Backed by over $300 million and strategic partnerships with global leaders across mining, steel, and big tech, momentum is on our side.

The Senior Cost Accountant is a highly visible, high‑impact role within Electra’s growing accounting team—offering a unique opportunity to help build and scale world‑class manufacturing accounting processes from the ground up. This role sits at the center of Electra’s transition from development to demonstration plant operations and ultimately to full‑scale manufacturing.

You will take ownership of critical cost accounting and fixed asset processes, including inventory valuation, construction‑in‑progress (CIP), and manufacturing cost analytics, while playing a pivotal role in shaping the systems, controls, and reporting infrastructure that will support Electra’s next phase of growth. This is a hands‑on position ideal for someone who thrives in a dynamic environment and is excited to drive both operational insight and process transformation.

The Senior Cost Accountant will partner closely with Operations, Engineering, Supply Chain, and FP&A to enhance cost visibility, improve accuracy, and deliver actionable insights that directly influence business decisions. You will also be a key contributor in strengthening internal controls, supporting audit readiness, and scaling accounting processes in alignment with GAAP.
