At R3, we are committed to providing our clients with best-in-class solutions for all of their IT needs. We are relentless in our pursuit of excellence and dedicated to providing our clients with unsurpassed quality, service, and value day in and day out. As we continue to grow and innovate, we are seeking passionate and dedicated individuals to join our team. If you’re ready to join our mission of setting the standard for IT excellence, we are looking for a talented Assistant Controller to join our team.

We are seeking a highly driven Assistant Controller to support a growing and scaling organization in the IT services industry. This role is ideal for a hands-on accounting leader who thrives in fast-paced environments, understands operational finance within a services model, and enjoys building processes that scale.

You will oversee core accounting functions, manage both domestic and offshore team members, and play a key role in strengthening financial operations, audit readiness, and revenue accuracy. This is not a purely oversight role- we need someone who can roll up their sleeves while also leading and developing a team.

This position is remote; however, candidates must be located in the Washington, DC, Maryland, or Virginia (DMV) area. Local presence is required to support leadership collaboration, periodic in-person meetings, and ongoing alignment as the company continues to grow and scale.

Preferred Qualifications

• Experience in IT services, MSP, or professional services environment

What We’re Looking For

• A builder - someone who has supported a company during growth or scaling
• A leader who can manage people but is not afraid to get into the details
• A process-oriented thinker who can improve systems without overcomplicating them
• Someone comfortable operating in a fast-moving, entrepreneurial environment
