  • Prepare monthly financial statements according to the standards above

  • Techno-economics: work with engineering to build fixed-asset registers, cost models, depreciation schedules, and model different scaling plans to make truly ROIC-driven engineering decisions

  • Structure and execute working capital facilities, equipment financing, and any venture debt to bridge to production scale

  • Support the CEO in capital raising through building the company's financial models, preparing data rooms, and financial due diligence responses

Preferred Qualifications

  • Background in manufacturing finance operations, including planning major capital projects
