Controller

Company Overview : InterAgency, Inc. is a mission-driven, minority-owned environmental consulting and permitting firm based in Washington, DC. For the last decade, InterAgency has played a critical role in some of the National Capital region’s largest infrastructure projects – including billion-dollar tunnels to prevent flooding and improve water quality, seawalls to combat sea level rise, transportation infrastructure to electrify bus transit, and water pipe replacement programs to expand access to clean drinking water. We are experts in the planning and implementation of large-scale public infrastructure and commercial development, working with public agencies, global engineering firms, developers, and general contractors to strategically manage regulatory complexity and risk.

• Supervise and coach junior accounting staff in AP / AR, expense classification, reconciliations, and time tracking; establish clear accountability and process documentation.
• Collaborate with payroll processors and HR to ensure accurate, timely, and compliant payroll across multiple states and benefit programs.
• Maintain and continuously improve internal financial dashboards, cashflow tracking, and KPI tools to enable transparent, real-time decision-making.
• Prepare for and coordinate annual external audits, tax filings, and financial reviews; liaise with external CPA firms, legal counsel, and lenders as needed.
