Meet the team

Jacob Payne, PE

Welcome toThreeForty Engineering, where passion meets professionalism! I'm Jacob Payne, the creative mind behind this venture. With a profound love for engineering, I have dedicated myself to improving this world through my ideas, solutions, and engineering abilities. My journey to become a Professional Engineer has been shaped by years of hands-on experience, continuous learning, and an unyielding commitment to excellence.

My Story

Growing up, I was always fascinated by how the world works! Anything that can be built, can be broke. Anything that can be broke, can be fixed. It blew my mind to learn there is an entire science dedicated to this idea. This fascination soon turned into a deep-seated passion, driving me to explore the intricacies of mechanical engineering. I graduated from Texas Tech University with a Bachelor of Science in Mechanical Engineering. Through years of dedication and hard work, I honed my engineering abilities, gaining valuable insights and expertise along the way. Eventually, this path led me to pursue the title of Professional Engineer.

I am elated to say I am a Licensed Professional Engineer in the great state of Texas with the ability to provide solutions to the entire state of Texas. I have the unique ability to rapidly serve my local area and provide solutions to the greater DFW Metroplex!

What Sets Me Apart

With over a decade of real-world engineering experience, I am able to offer expert guidance in design, analysis, and optimization. I ensure each project is efficient, cost-effective, and sustainable. I take pride in my ability to think outside of the box to provide solutions that fully meet your requirements!
