About The Team:

\n

Our client is scaling a hardware-plus-energy business and their accounting team builds the financial foundation that makes that scale possible. The team designs and runs the systems that turn manufacturing activity, member agreements, and energy market participation into accurate, decision-ready financials — so leadership knows exactly where the company is making money, where it is not, and how fast it can grow. This work directly shapes pricing, investment, and operational strategy, not after the fact but in real time as the company evolves. An exceptional candidate will be excited to build principles-first processes in a complex business and have a clear line of sight from debits and credits to the decisions that determine the company trajectory.

Please note: Our client is a startup, which means priorities shift and evolve quickly. Your role may expand or change based on the needs of the business at any given time, so the responsibilities listed may not be exhaustive.
