About Travertine Tech

Boulder, CO

Travertine is a Climate Tech start-up based in Boulder, CO that is rapidly scaling an electrochemical technology for carbon dioxide removal (CDR) and sustainable critical element extraction. Our process takes carbon dioxide from the air and sources of waste sulfate to produce carbonate minerals, sulfuric acid, and hydrogen. The sulfuric acid is used in extraction of critical elements like lithium and nickel for EV batteries and phosphorus for fertilizer. The Travertine Process was developed by Prof. Laura Lammers at her UC Berkeley lab. Travertine was founded in 2022 to scale this process to gigatons of CDR and massively reduce industrial waste.

In 2022, we raised a seed round from the Grantham Foundation and Clean Energy Ventures, we were one of the first companies to receive pre-purchases of CDR from the new Stripe-led $1B Frontier fund, and we received a $2M grant from the DOE’s ARPA-E program. We were named C&EN 10 startups to watch in 2022, a Bloomberg NEF Pioneer in 2023, and are part of the RMI Third Derivative 1st Gigaton Captured program. We have recently closed a substantial convertible note round, received a state agency grant to build a Demo Plant, and are in engineering for the Demo Plant to be commissioned in mid-2025.

What You Will Do

We are seeking a highly experienced process engineer to take the lead on scaling our process from pilot to commercial scale. This role will lead engineering for the scale-up and commercialization of our process from our current in-house pilot-scale (10 kg/day of sulfuric acid production, TRL5), through our Demo Plant (0.4 TPD sulfuric acid), and ultimately to world-scale sulfuric acid production plants (1000+ TPD of sulfuric acid production). Our process is well suited to scale rapidly as it combines three industrialized unit operations in a novel way: salt-splitting electrolysis, hydrometallurgy, and CO2 direct air capture with a cross-flow cooling tower. Work with the company leadership to refine and then take the lead on executing a plan for process scale-up.

Who You Are

As the Director of Process Engineering, you bring over 15 years of extensive experience in chemical process engineering, specializing in advancing projects from pilot through demo to commercial scale. You have a proven track record in taking novel technologies to full-scale commercialization, with expertise in strategic planning, project management, and operational optimization. Your hands-on approach, innovative mindset, and commitment to efficiency and cost reduction ensure successful project execution and operational excellence.


This role is based in our headquarters in Boulder, CO.

Salary range is $130,000-$190,000/yr and is highly dependent on skill set and experience.
