A Future to Grow Into
We champion a well-rounded approach to preparing for a career in construction. We believe it's best to combine hands-on experience with traditional classroom learning. Our internships and early career opportunities are designed to give students and recent graduates a solid understanding of the construction industry in the real world. As an intern, you will get to work on real projects, making real impacts in our community.
What does it mean to be the right person? It means you embody our core values and live them daily. At Marksmen General Contractors, we hire and retain only those who align with these principles. You can find a brief overview of our core values below or explore them in more detail on the core values page linked above. Being the right person also means fully embracing and executing our core process: Plan with Precision, Communicate with Clarity, and Execute with Excellence.
At Marksmen General Contractors, every role is carefully defined by a few essential responsibilities, ensuring clarity and purpose. We seek individuals who not only understand these responsibilities but are passionate about fulfilling them and have the capacity to execute them with excellence. Finding the "right seat" means you get it, want it, and have what it takes to do it.
Mandy’s interest in construction grew not only through her personal connection to the business as Mark’s wife but also through her involvement in business development, marketing, and now, employee development. She’s proud to support this dynamic workforce that requires tactical talent and a dedication to the details and risks involved in building structures. Her favorite part of the job is collaborating with others—whether it’s brainstorming new ideas with the marketing team or solving challenges with leadership. She enjoys being part of a team where different perspectives come together to innovate and find effective solutions.
For Samantha, her internship at Marksmen GC was more than just hands-on experience—it was an introduction to a culture that values teamwork, learning, and the stories behind the people who build. The relationships she formed and the lessons she learned shaped her confidence in the field. Her advice to new interns? Keep moving forward. Progress might feel slow, but when you look back at day one, you’ll see just how far you’ve come. She stays motivated with “fire music” to start her day and focused on the end goal—gaining knowledge and seeing the final result take shape.
I never planned on a career in construction, but somehow, I ended up right where I was meant to be. I was originally accepted to Texas A&M for Construction Science before pivoting to a business degree, and now, in Marketing & Business Development at Marksmen GC, I see how both paths have shaped my approach. Success in this role isn’t about mastering just one thing—it’s about being a jack of all trades, adapting to new challenges, and finding creative solutions. Every pursuit, every proposal, and every project brings something different. Some of our best work has gone unnoticed, while others have been game-changers. But that’s the nature of the job—learning, refining, and pushing forward. What keeps me coming back day after day is the opportunity to chase new ideas, tell great stories, and be part of something bigger than just the next pursuit.
