Square Robot is a Massachusetts-based robotics company and the innovator in autonomous, submersible robotic inspection of above ground storage tanks. Our robots inspect tanks while they remain in service, eliminating the need for human entry into hazardous environments and making inspections safer, faster, and more sustainable. From our Westborough, MA headquarters and our service facility in Houston, TX, we deliver inspection programs for blue‑chip energy and industrial clients around the world.

Because we work with large, sophisticated customers across multiple countries and currencies, our accounting environment is hands‑on and detail‑rich. This is an opportunity to own real transactional accounting in a growing company and work directly with our Accounting Manager and CFO.

The Staff Accountant is responsible for the day‑to‑day transactional accounting activities of the business: payroll, accounts receivable, accounts payable, and collections, along with reconciliations and month‑end close support. The role supports a growing, project‑based business with domestic and international customers, multiple legal entities, and transactions in multiple currencies. The role reports to the CFO and works closely with the Accounting Manager, and interacts regularly with project, operations, and commercial colleagues, as well as with customers and external advisors.

Success means our billing is accurate and timely, our vendors and team are paid correctly, our cash is collected, and our books are clean and close on schedule.
