About the Role

We are looking for an Accounting Manager to own and operate the day-to-day accounting function at TENEX as we scale. This role is foundational — you will be the first dedicated accounting hire, owning the close, ensuring the integrity of our books, and building the controls and processes that will support TENEX through its next stages of growth.

Reporting to the Director of Finance / Operations, you will serve as a hands-on operator and trusted partner across the business — owning month-end close, AP/AR, cash management, technical accounting, and audit preparation. You will also play a key role in standing up scalable accounting processes from the ground up.

This role is starting as an individual contributor with the expectation of building and leading a team over time. If you’re excited about building an accounting function at a fast-scaling, AI-native company, this is the role.
