This resume, much like the author, is always under construction...

Robert H. Engelhardt

With over 16 years of experience as a professional software developer, I have provided critical support to the National Nuclear Security Administration (NNSA) and the Department of Energy (DOE) in mission-critical activities. I have spent the last decade at Sandia National Laboratories (SNL), and previously worked at the Kansas City National Security Campus (KCNSC). I have led multiple projects and teams of developer and developer adjacent positions, gaining a wide range of experience and technical skills across various specialized disciplines, software domains, and integrated systems. My work has had a positive impact on software development and architectural implementation at the laboratories, as well as on cyber security posture, network topology, and laboratory software systems. I have been instrumental in fostering Agile methodology, leading software development teams, mentoring interns, and staff members, and providing guidance on best practices and Computer Science solutions. I am recognized as a Subject Matter Expert (SME) and have regularly engaged with laboratory and non-laboratory staff at conferences, presenting on a variety of topics. My expertise in software development has influenced practices and procedures. I am the lead developer for three open-source software packages and have been heavily involved in the creation of several products shared with the DOE/NNSA ecosystem through the Government Use Notice (G.U.N.) process. My engagement in the development discipline has been both personally rewarding and has shaped the perspectives of others.
