Travertine
Converts mining waste into sulfuric acid
Travertine is an Industrial Transformation company based in Boulder, CO, that is rapidly scaling a technology for sulfur-decoupled production of critical minerals, starting with phosphate. Our technology enables large-scale circularity in extractive industries while simultaneously decarbonizing building materials. We do this by electrochemically recycling chemical byproducts, sulfate wastes, into sulfuric acid and valuable mineral co-products.
Sulfuric acid is the world's most used inorganic chemical and is vital for producing a wide range of critical elements including phosphate, lithium, copper, nickel, and rare earth elements. Travertine's technology solves the dual problems of sulfur supply vulnerability and large-scale chemical waste disposal. Our transformative process changes the fundamental material balance of critical mineral production, laying the groundwork for an industry liberated from fossil inputs and their legacy impacts.
Since founding, Travertine has raised over $29M in capital, including over $5M in US Federal and State government grants. We are an accomplished and driven team recognized by C&EN 10 startups to watch in 2022, Bloomberg NEF Pioneers in 2023, RMI Third Derivative 1st Gigaton Captured program in 2024, Mining Cleantech Challenge in 2026, and are a founding member of the Carbon Removal Alliance. Travertine designed, built, and successfully operated our core technology Demonstration Plant in Rochester, NY for over 3,000 hours, and delivered the project on-time and on-budget. We are now developing our first commercial plant, which will be the only new phosphate plant built on US soil in over 50 years.
The Instrumentation & Controls Engineer will be responsible for developing instrumentation and controls (I&C) systems for Travertine’s in-house lab and pilot facility (Boulder, CO), as well as refitting, improving and maintaining I&C systems for our NY-based demonstration plant, and commercial-scale chemical process systems. This role will be working on advanced processes that combine electrochemical salt splitting, electrolysis, and chemical production and separation unit operations for phosphate and sulfuric acid production.
This role will have end-to-end responsibility from I&C systems, from control philosophy and control narratives through instrumentation selection, electrical design and wiring, PLC programming, HMI development, commissioning, troubleshooting, and operation as we scale our process technology. This role will engage and manage external contract work associated with I&C design and build as needed, as well as manage both internal and external workflows associated with all I&C work.
This role is onsite and based in our Boulder, CO headquarters.
Salary range is highly dependent on skill set and experience, approximately $105,000 to $130,000 per year.

Converts mining waste into sulfuric acid
Travertine Technologies develops a climatetech process that removes carbon dioxide and recovers critical metals from mining waste. Its method uses sulfate waste from mining to produce sulfuric acid, which then leaches valuable metals from mine tailings. The same process mineralizes CO2, permanently sequestering it as carbonate. This creates a circular approach that turns waste into useful products and lowers emissions in mining, fertilizer, and cement industries. The company aims to scale its technology for commercial use, supported by a demonstration plant and funding, and to drive industrial decarbonization and resource recovery by offering a combined solution of waste valorization and carbon removal.
