In an era when microelectronics and semiconductors underpin everything from smartphones to fighter jets, few voices bridge the worlds of advanced technology, defense strategy, and storytelling quite like Daniel Marrujo. As host of the Micro Journeys podcast and Managing Director of Trusted Strategic Solutions (TSS), Marrujo is pioneering conversations and solutions at the intersection of innovation and national security.
Marrujo’s path into microelectronics was sparked early, inspired by his engineer father and shaped by mentors like Dr. Richard Savage, who introduced him to the vast potential of microelectronics at Cal Poly. His hands-on exposure — working in cleanrooms, “suited up” in bunny suits — was more than an academic experience; it was a gateway into an industry enabling advancements in AI, telecommunications, and defense.
His career trajectory reads like a masterclass in seizing opportunities. After a Raytheon-funded master’s thesis on quantum dot–enhanced solar cells, Marrujo joined the company to work on classified missile systems. This early exposure to the defense sector ignited a passion for connecting engineers with the operators, the “warfighters,” who rely on their technology.
That passion deepened at the Defense Microelectronics Activity (DMEA), where Marrujo climbed from junior engineer to the organization’s first Chief Strategy Officer. Here, he tackled one of the defense industry’s most persistent challenges: bridging the gap between those who design the electronics and those who use them in mission-critical environments.
His vision took full shape with the founding of Trusted Strategic Solutions. TSS now leads initiatives that range from modernizing radiation testing infrastructure for advanced electronics to aligning cutting-edge technologies with the precise needs of defense, health, and energy agencies. With a global network of over 65 expert consultants, from Pentagon leaders to NASA scientists, TSS functions as a “translation layer” between industry innovation and government requirements.
But Marrujo’s influence doesn’t stop at the boardroom or laboratory door. He is also the voice behind Micro Journeys, the only podcast of its kind in the microelectronics, semiconductor, and defense technology space. The show spotlights the people and organizations solving America’s most complex problems—from securing the nation’s critical supply chains to developing technologies that protect warfighters in the field.
Since its launch just four months ago, Micro Journeys has experienced explosive growth, amassing nearly 400,000 views on YouTube and attracting more than 16,000 subscribers. Marrujo’s ability to turn high-stakes, highly technical subjects into engaging, accessible conversations has struck a chord with both industry insiders and curious listeners. The podcast is quickly becoming a trusted platform for thought leadership in an arena that rarely receives mainstream attention.
Through Micro Journeys, Marrujo not only documents the cutting-edge work happening behind the scenes, but also humanizes the innovators — engineers, strategists, policymakers — who are shaping the technological backbone of national security. In doing so, he’s building a bridge between the public and a world that often operates out of view.
He’s also been at the table for pivotal industry shifts, contributing to policy discussions that informed the CHIPS Act and advocating for advanced packaging capabilities to remain on U.S. soil. For Marrujo, it’s not just about building technology, it’s about building resilience.
“Every single day presents another set of opportunities,” he says. “If we can keep making a difference, then I’m extremely excited for what’s next.”
From cleanrooms to the corridors of the Pentagon, Daniel Marrujo has proven himself not just a technologist, but a connector, bridging disciplines, sectors, and even nations to ensure that the technologies powering the future are ready for the challenges of today.
