Analytical Chemistry Technician

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.

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.

Travertine is seeking an Analytical Chemistry Technician to join our analytical laboratory team at our Boulder, Colorado headquarters. The successful candidate will perform routine analytical testing and sample preparation while working closely with laboratory management, researchers, engineers, and other technical staff. This position requires strong attention to detail, reliability, clear written and verbal communication, and the ability to consistently follow standard operating procedures (SOPs), quality control requirements, and safe laboratory practices.

Candidates should have a working understanding of fundamental chemistry concepts and laboratory calculations necessary to perform accurate chemical analysis. Preference will be given to candidates with previous experience in an inorganic analytical laboratory, particularly experience with analytical instrumentation, sample preparation, QC practices, and laboratory documentation. This is a full-time, onsite salaried position.

• Sample preparation and testing, including weighing, dilutions, digestions/prep, routine instrument operation and analysis following training and qualification
• Quality and documentation activities, including: sample tracking, data entry, QC checks, and SOP compliance
• Instrumental analysis on inorganic samples including IC, ICP-OES, TIC/TOC, UV-Vis spectrophotometry, titration systems, and related laboratory instrumentation
• Wet chemical analyses such as leaching, solvent extraction, ion exchange, gravimetric analyses, ISE analysis, and other established laboratory methods
• Laboratory cleanup, organization, and general housekeeping
• Support inventory management for laboratory supplies and chemicals.
• Routine instrument operation, cleaning, maintenance, and basic troubleshooting after training and qualification
• Preparation and verification of QC standards, reagents, and quality control samples.
• Initial data verification and reviews, including identification and escalation of unusual results or QC failures
• Construct and support bench- and pilot-scale experimental systems as directed

• Associate’s or bachelor’s degree in chemistry, chemical technology, environmental science, or a related technical field or equivalent relevant laboratory experience
• 1-3+ years of laboratory experience preferred, particularly in an analytical, inorganic,…
