Andrew Sitework is a premier public infrastructure contractor specializing in water, sewer, roadway, and sitework projects exclusively for municipalities, counties, and public agencies across Florida. Since 2008, we have built a reputation for precision, compliance, and delivering complex projects on time and within budget. We are currently seeking an office assistant to join our team in Fort Myers, Florida.

• Health, Dental, and Vision Insurance.
• 5-day work week with excellent work-life balance.
• Opportunity to work on meaningful public infrastructure projects that improve Florida communities.
• Supportive team environment and a stable, growing company.

What We’re Looking For

We are looking for someone who wants to become an important part of our office team rather than simply perform basic clerical duties. This position will have exposure to the entire construction process—from estimating and bidding a project, to supporting the project while it is under construction, to assisting accounting with job costs and billing. The right candidate will be organized, proactive, willing to ask questions, and interested in learning how an underground utility construction company operates. There is an opportunity for the position to grow as the employee gains experience and becomes familiar with our projects and processes.

Key Responsibilities

The ideal candidate is detail-oriented, comfortable working with numbers and documentation, and able to manage multiple priorities. Construction experience is helpful but not required. We are looking for someone who is willing to learn the business and grow into additional responsibilities over time.
