About the Role As a Senior Accountant at Armada, you will be a key member of our growing Finance team, responsible for maintaining the integrity of our financial records as we scale rapidly. You will manage assigned areas of the general ledger function, support month-end and year-end close processes, and partner cross-functionally with teams across the business to ensure accurate and timely financial reporting. This is a general GL role with real breadth. Depending on business needs, your scope will span AP, AR, revenue, expenses, fixed assets and depreciation, debt, and leases, and it will shift as Armada grows. Our Galleon program (modular, deployed data centers) is a core part of the business and a meaningful piece of this role, including inventory, CIP, capitalization, and fixed asset accounting, but it is one of several areas you will cover rather than the whole job. The ideal candidate is technically strong, highly organized, and excited about building scalable processes at one of the most exciting companies in AI infrastructure. This is a high-impact role for someone who thrives in ambiguity, takes ownership, and enjoys building scalable processes in a high-growth environment. Location.
