For Sze Hou Loh, engineering has always been less about the company name on the badge and more about the problems waiting to be solved. Over the past several years, he’s built a career that spans energy systems, sustainability research, and consumer technology — a trajectory that reflects how modern engineers are redefining versatility.
Loh’s foundation was laid at Georgia Tech, where he earned a degree in Mechanical Engineering. During his undergraduate years, he explored different branches of applied science, working in several research labs, including the Electrochemical Systems and Clean Energy Lab. His research focused on developing alternative cathode materials that reduce dependence on rare-earth metals — an early sign of his interest in sustainable innovation.
From there, Loh’s career unfolded through some of the world’s most technically demanding industries. At Tesla, he joined the cell engineering team, validating the company’s 4680 battery cells — the same technology underpinning Tesla’s next generation of energy storage. “Tesla taught me what it means to work in a high-velocity environment,” he says. “You learn to be comfortable with uncertainty, to make decisions based on incomplete data, and to adapt constantly.”
That mindset served him well when he transitioned to Enphase Energy, a leading renewable energy technology company. As a Mechanical Engineer, Loh contributed to the development of the Powerpack 1500, a commercial energy storage product. His work on the battery and enclosure design earned a design patent published in Australia and New Zealand, a milestone that underscored his growing expertise in bringing physical products to market.
Loh describes Enphase as a formative chapter — one that deepened his understanding of the full product lifecycle. “It was the first time I got to see something I designed go from concept to commercial release,” he says. “You start to understand how every design decision, no matter how small, affects manufacturing, cost, and user experience.”
His career later expanded into product design engineering, where the emphasis shifted from systems performance to how devices fit seamlessly into people’s lives. The move was both natural and intentional — a culmination of his experiences across validation, mechanical design, and systems integration. “Each role taught me something different about how to think as an engineer,” Loh explains. “I’ve learned that the ability to learn quickly and apply knowledge across domains is one of the most valuable skills you can have.”
Today, Loh’s focus remains on designing technology that is as elegant as it is functional — whether that means refining the mechanical integrity of a consumer device or optimizing energy efficiency in industrial systems. Across every project, his guiding principle has stayed the same: keep learning, stay adaptable, and let curiosity drive the work.
That perspective has made his career a reflection of a broader truth about engineering in the modern age — it’s no longer about mastering one discipline, but about connecting many. As Loh puts it, “Engineering is really about exploration. The tools and industries may change, but the mindset doesn’t.”
