About the team
Base is scaling a hardware-plus-energy business and our 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 we're making money, where we're not, and how fast we 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 Base's trajectory.
