Permutive is looking for a seasoned Controller or Senior Controller to own the accounting function across our US and UK entities. Reporting directly to the CFO, this person will be responsible for the integrity of our books, the timeliness of our close, and full compliance with statutory and regulatory obligations on both sides of the Atlantic. This is a hands‑on role in a lean, high‑expectations finance team — you will do the work, not just review it.

• Own the monthly, quarterly, and annual close process end‑to‑end, including GL management, reconciliations, accruals, and intercompany eliminations across our US and UK entities

• Prepare and maintain US GAAP‑compliant financial statements; manage the annual audit and the external auditor relationship

• Drive revenue recognition under ASC 606 across subscription and usage‑based contracts, independently documenting positions and identifying edge cases
