WORK HISTORY
Snr Plant Operations Manager @Twelve
CA, US
With over 20 years in operations and engineering, I’ve built my career around leading teams, running safe and reliable plants, and helping people do their best work. I’ve managed complex start-ups, strengthened process safety systems, and supported both traditional refineries and first-of-a-kind clean-energy facilities. What I’m most proud of is building strong teams and clear operating systems that make work safer, smoother, and more rewarding for everyone involved. I lead with empathy, clarity, and a commitment to continuous improvement—because when people feel supported and aligned, great operations naturally follow.

ABOUT MARK SMITH P. ENG
As a Professional Engineer and senior operations leader with more than two decades of experience across refining, process engineering, and EH & S leadership, I specialize in building safe, reliable, and high-performance operations in both traditional oil & gas and emerging clean-energy technologies. My career has included leading large multidisciplinary teams, commissioning and starting up complex facilities, and designing operational systems that meet the highest standards of process safety, regulatory compliance, and business readiness. Whether managing a refinery, developing an EH & S organization from the ground up, or guiding the build-out of a first-of-its-kind carbon-to-fuel plant, I bring disciplined execution, clear decision-making, and a safety-first mindset to every challenge.Today, I’m focused on applying that operational foundation to the next generation of energy technologies—particularly sustainable aviation fuel (SAF), electrolysis, Fischer-Tropsch systems, and AI-enabled operations. I’m passionate about creating cultures where teams feel empowered, accountable, and aligned around shared goals, because great operations are built on people as much as processes. With a track record of driving improvements, navigating organizational transitions, and delivering results in high-stakes environments, I’m committed to leading organizations through growth, transformation, and the adoption of innovative technologies that make energy cleaner, safer, and more efficient. If you’re building something complex, scaling something new, or transforming an existing operation, I create the systems and conditions that make it succeed.
