We’re proud to continuously strengthen our team with highly skilled professionals who bring deep expertise, proven leadership, and a passion for advancing infrastructure and design projects with integrity and excellence. This spring, we’re excited to welcome five remarkable individuals whose extensive federal experience and diverse backgrounds align perfectly with our mission and values. Please join us in getting to know Katie Alexander, Josh Smalley, Steven Belcher, Mark Meng, and Lucas Jimenez.
Katie Alexander — Project Engineer III
Katie Alexander earned her Bachelor of Science in Civil Engineering from Oregon State University in 2014. She began her professional journey with the Western Federal Lands Highway Division, where she gained valuable hands-on experience working on a broad range of projects—from urgent emergency site repairs to large-scale corridor reconstructions. Her work has consistently demonstrated technical precision and a commitment to public safety and infrastructure resilience.
Beyond the office, Katie is deeply devoted to her family. She is a mother of two young children with a third on the way, and balances her demanding career with a rich home life that includes gardening, raising chickens, and tackling various household projects. Currently, Katie and her family are preparing to relocate to her childhood home near the base of Mt. St. Helens, a move that reflects her strong ties to the Pacific Northwest and a lifestyle centered around community and nature.
Josh Smalley — Design Engineer I
Josh Smalley’s journey with DJ&A began as an intern in the summer of 2024 and has grown steadily into a full-time role within our Civil Engineering & Design group in Missoula, Montana. He recently graduated from Carroll College with a Bachelor of Science in Civil Engineering and passed the Fundamentals of Engineering (FE) exam—a critical step toward professional licensure.
During his time at Carroll, Josh distinguished himself not only academically but also as an engaged campus leader. He served as president of Engineers Without Borders and contributed meaningfully to the Student-Athlete Advisory Committee. These leadership experiences underscore his commitment to service and teamwork.
Outside of engineering, Josh enjoys hunting, fishing, hiking, and staying active—habits inspired by his background as a collegiate track and field athlete. His love for the outdoors and dedication to community-driven projects make him a great fit for DJ&A’s mission of thoughtful, sustainable design.
Steven Belcher — Senior Project Manager
With more than 28 years of experience, Steven Belcher brings exceptional depth in bridge analysis, design, inspection, and project leadership. Steven holds a Bachelor’s and Master’s degree in Civil Engineering from Tennessee Tech University and the University of Tennessee, respectively.
Steven has built his career with the Tennessee Department of Transportation and the Federal Highway Administration. For the past 16+ years, he served as a senior designer and bridge design team leader at the Central Federal Lands Bridge Office in Lakewood, Colorado. In this role, he oversaw bridge projects on federally owned lands throughout the western United States, demonstrating technical expertise and strategic leadership.
Outside of his professional life, Steven enjoys an active lifestyle filled with skiing, biking, hiking, and traveling. He’s also a passionate fan of college football and Formula One racing, often sharing these interests with his wife of 24 years and their three children. Steven’s blend of experience and enthusiasm will be a tremendous asset as he embarks on this next chapter with DJ&A.
Mark Meng — Senior Project Manager
Mark Meng comes to DJ&A with an impressive federal leadership background spanning over two decades. Before joining us, Mark was the Director of Engineering and Fleet for the USDA Forest Service’s Southern Region (Region 8), based in Atlanta, Georgia. In that role, he provided executive oversight and guidance for the Forest Service’s largest disaster relief program, managing a portfolio exceeding $3.5 billion.
Mark’s career with the USDA Forest Service began in 2016 as Acquisitions Branch Chief over the Job Corps Support Branch. Prior to that, he spent more than 16 years with the Central Federal Lands Highway Division of the Federal Highway Administration, where he held key positions including Acquisitions Program Manager, Construction Operations Engineer, Project Manager, and Highway Design Engineer.
He holds a Master’s in Business Administration from Colorado State University and a Bachelor of Science in Civil Engineering from the University of Colorado at Denver. Mark is both a licensed Professional Engineer (PE) since 2005 and a certified Project Management Professional (PMP) since 2006.
When not leading complex engineering initiatives, Mark enjoys hiking, traveling, and brewing craft beer, bringing the same precision and passion to his hobbies as he does to his professional endeavors.
Lucas Jimenez — Design Engineer III
Lucas Jimenez brings over 25 years of diverse civil engineering experience, beginning with his service in the U.S. Marine Corps. Following his military career, Lucas transitioned to the private sector before dedicating many years to federal service. His broad background informs a design philosophy rooted in sustainability and creating spaces that are both beautiful and highly functional.
Lucas is deeply committed to environmentally responsible design and strives to integrate this ethos into every project. Outside of engineering, he channels his creativity through garden design and enjoys the strategic challenge of chess.
His wealth of experience and passion for sustainable design make him a vital addition to DJ&A’s team.
At DJ&A, we value the exceptional expertise and leadership our new colleagues bring. Their collective federal service experience strengthens our capacity to deliver innovative, sustainable, and community-focused engineering solutions. We look forward to the contributions they will make to our projects and culture.
