Assistant Controller, Government Accounting & Compliance

About the role

Our Finance team is seeking an Assistant Controller, Government Accounting & Compliance to support the Controller and broader Accounting team during a period of rapid growth. This person will play a critical role in both the day-to-day accounting function and in building the infrastructure needed to support government cost accounting, cost reimbursement reporting, and government audit readiness. This role is intended for someone who can operate as a strong accounting leader while also rolling up their sleeves. In addition to core Assistant Controller responsibilities such as owning the month-end close process, this person will help design, implement, and monitor the controls, reporting, and compliance processes needed to support a more complex government-facing environment. The right candidate will be excited by the opportunity to build. They should be comfortable working in an environment where some processes exist, some need to be strengthened, and others need to be created from scratch. The candidate should have a working knowledge of cost accounting standards for government contracts and experience interfacing with government agency officials and auditors. This role will be highly cross-functional and visible, with regular interaction across Finance, Legal, Operations, Program teams, and external auditors / advisors.

Responsibilities

• Help manage the monthly, quarterly, and year-end close processes, ensuring timelines are met and issues are proactively identified and resolved.
• Lead the build-out of accounting and reporting processes needed to support government-funded and cost-reimbursable work, including developing frameworks for project costing, indirect rate calculations, and identifying allowable vs. unallowable costs.
• Develop processes to track, reconcile, and report costs in a manner that is supportable under government audit and reimbursement requirements including tracking and reviewing the accumulation of direct and indirect costs.
• Help document and operationalize processes so controls are not only designed appropriately but also executed consistently.
• Partner with internal and external stakeholders to prepare for financial audits, government audits, and any future Single Audit / Yellow Book-related requirements if applicable.
• Partner with Finance leadership to assess process gaps and lead the development of documentation, policies, and operating procedures needed to remediate those gaps in advance of new government awards or reporting requirements.
• Partner with program, operations, legal, and external advisors on government accounting considerations, reporting expectations, and implementation needs.
• Drive process improvement and automation initiatives to improve scalability, control, and reporting quality.
• Help ensure the finance organization can support a high-growth company with increasing complexity while maintaining a practical, business-oriented approach.
• What You Should Have
• 8+ years of progressive accounting experience, with at least 4 years of experience in government contracting, government accounting, or another environment with cost reimbursement, indirect rates, and contract compliance requirements.
• Strong working knowledge of government accounting requirements, including cost reimbursement reporting, allowable vs. unallowable cost treatment, cost allocation methodologies, and audit-ready support for reimbursable spend.
• Experience supporting government audits or similarly rigorous compliance environments, including exposure to DCAA, FAR / CAS concepts, incurred cost submissions, Single Audit, Yellow Book, or related frameworks.
• Demonstrated experience building or strengthening controls, policies, and procedures required to operate in a more formal government-compliance environment.
• Experience preparing for, supporting, or remediating findings from government audits, Single Audits, or Yellow Book / GAGAS-related environments.
• Strong foundation in U.S. GAAP
