Office Manager

Company Overview

We are proud to partner with a Custom Integration Technology company based in St. Peters, MO. Founded in 1988, this team has grown from a small sound system contractor into a full-service systems integrator. Their expertise spans professional sound reinforcement, acoustics, video display, distribution, lighting, automation, networking, and more. With a portfolio that ranges from private homes to churches and boardrooms, their mission is to enrich lives through thoughtful, high-performance technology solutions.

This is a company where passion meets precision. Every project is treated as the most important one they've ever taken on. Their Midwestern values and commitment to quality make them a trusted partner in the residential AV space—and a place where employees are given the opportunity to grow, lead, and innovate.

Why Join Us?

• Be Part of a Company That Truly Cares
  This team treats every project—and every person—with intention and care. You'll join a company that values quality over quantity and people over process. They take pride in their work and support each other along the way.
• A Stable, Grounded Work Environment
  You won’t find corporate chaos or constantly shifting priorities here. Instead, you’ll be part of a tight-knit team where everyone pulls their weight, respects each other’s time, and communicates clearly. The culture is built on Midwestern values—pragmatism, loyalty, and integrity.
• Make a Real Difference Every Day
  In this role, you’ll be far more than just an administrator—you’ll be a linchpin. From keeping the office running to helping customers feel cared for, your contributions will have a direct impact on the company's operations and reputation. You'll be relied on, appreciated, and trusted.
• Work Closely With Leadership
  You’ll report directly to the owner and be empowered to take initiative. While the owner may not be in the office full-time, you'll have regular communication and support to ensure you're aligned and set up for success. This is a role with autonomy and real responsibility.
• Room to Grow at Your Own Pace
  Whether you want to take on more advanced bookkeeping or grow into new areas of responsibility, your role can evolve over time. As trust is built, you’ll have the opportunity to absorb more of the operational and financial duties currently handled externally—if you want to.
• A Role That Fits Real Life
  We’re not looking for someone chasing titles—we’re looking for someone who values consistency, clarity, and impact. This is a great fit for someone with experience and maturity who wants a dependable, fulfilling role without the stress of climbing a corporate ladder.
