Are you a highly capable Office Administrator who thrives in ownership, follow-through, and keeping complex operations running smoothly? Are you known for anticipating needs, maintaining strong systems, and making everything more efficient? If so, we’d love to connect.

Thayer Design Build is seeking an experienced Office Administrator to support company leadership and oversee the administrative systems that keep our business running efficiently. This role is designed for someone who brings confidence, judgment, and consistency to their work and takes pride in being a steady, trusted presence in a high-performing organization.

About the Role

The Office Administrator is a key operational role responsible for managing administrative workflows, coordinating information, and ensuring day-to-day execution stays organized and on track. This position exists to remove friction, support leadership priorities, and make sure important details and follow-ups are handled without prompting.

You’ll work closely with leadership in a fast-moving, high-standards environment where initiative, discretion, and reliability are essential. This is not a task-by-task role. It requires ownership, sound judgment, and the ability to manage responsibilities independently.

What You’ll Do

• Own and execute a wide range of administrative and office operations
• Manage spreadsheets, documents, tracking, and data entry with accuracy and consistency
• Handle incoming and outgoing phone calls, emails, and correspondence professionally
• Manage internal requests and track follow-ups
• Coordinate schedules, information flow, and task completion across the office
• Maintain organized systems, files, and internal processes
• Anticipate needs, identify gaps, and take action
• Ensure tasks are completed thoroughly, correctly, and on time

What We’re Looking For

• Proven experience as an Office Administrator or senior administrative professional
• High school diploma or equivalent required (Formal education beyond high school is welcome)
• Strong organizational skills and attention to detail
• Confidence working with spreadsheets, documents, and internal systems
• Clear, professional written and verbal communication skills
• Comfortable working independently and managing priorities without close supervision
• Reliable follow-through. If something is assigned, it gets done
• Professional, personable, and steady under pressure
• Humble, hungry, and smart

Construction or remodeling experience is not required. What matters most is experience, judgment, and consistent execution.
