About The Team

Base is scaling a hardware‑plus‑energy business and our accounting team builds the financial foundation that makes that scale possible.

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.
