Meet LLNL: Senior Engineering Technologist Jose Hernandez

Seven years ago, Jose Julian Hernandez took a chance on an internship at Lawrence Livermore National Laboratory (LLNL). Today, he is a senior engineering technologist at LLNL’s Center for Micro- and Nanotechnology, providing engineering support for projects ranging from medical implantable devices for neural research to custom-engineered products for various Laboratory groups.

Hernandez, who began his journey at LLNL in June 2018, initially saw the internship interview as a learning experience.

“I was a new student and didn’t think I’d even be considered for a position,” he said. “My idea was to take the interview just to get the experience, just to see what kind of questions they ask.”

Instead, his background in mechanical technology led to an internship focused on mechanical engineering, which eventually transitioned into a full-time role.

A graduate of San Joaquin Delta College in Stockton, Hernandez earned his associate degree in materials and electron microscopy, a field that involves the study and preparation of samples for electron microscopes, including scanning electron and transmission electron microscopy. He credits his education and a willingness to embrace new challenges for his success at the Lab.

“What I like most is being part of the puzzle for these innovative ideas,” Hernandez said. “New projects come with challenges, and I enjoy the satisfaction of solving issues and keeping progress moving.”

Outside of work, Hernandez strives for balance. He enjoys kayak fishing, golfing, camping with family and working in his garage, where he restored a 1968 Chevy pickup truck. He draws parallels between his mechanical interests at home and his work at LLNL, noting that problem-solving habits developed through tinkering and repairs have served him well in his professional life.

Hernandez’s curiosity and hands-on approach were fostered early on by his father, who taught him how to use tools and fix things around the house.

“Growing up, we couldn’t afford new tools, so we used what we had,” he said. “That taught me to become a better problem solver.”

Artistic pursuits have also played a role in Hernandez’s life. He spent six years as a tattoo artist and continues to enjoy photography and painting.

Raised in Stockton, Hernandez is one of six siblings. His parents, originally from Mexico, worked multiple jobs to provide for the family and instilled a strong work ethic.

“They always encouraged us to work hard and finish what we started,” he said.

Hernandez’s girlfriend, Eleanna Garza, who also works at LLNL, was instrumental in his decision to pursue the microscopy program at Delta College. The couple met in a Spanish class before joining the Lab, and they often connect with colleagues both inside and outside of work.

Reflecting on his career, Hernandez offers advice to newcomers: “Don’t overthink your environment and always remain curious. Ask a bunch of questions. Remember, you’re here for a reason.”

Looking ahead, Hernandez hopes to pursue a bachelor’s degree and continue growing both personally and professionally at the Lab.

“It seems like the Lab will definitely support that idea and that goal,” he said. “There’s a lot I’m excited about, whether it’s advancing my education or taking on new challenges here, I know I’ll have the support I need to keep moving forward.”
