The Geochemistry Technician will support the execution of geochemical monitoring and fluid sampling programs across Fervo's operating facilities. Reporting to the Geochemical Engineer, this role is responsible for collecting, handling, and processing geothermal fluid, gas, and water samples in the field; performing on-site analytical measurements; and maintaining the data integrity and documentation systems that underpin Fervo's geochemical program.

This role is field-forward. You will work directly on live flow streams at operating geothermal plants, execute established sampling protocols with precision, and flag anomalies that inform chemical treatment and corrosion management decisions. You are the hands and eyes of the geochemical program in the field.

Responsibilities

Field Sampling & Fluid Characterization

• Execute wellhead, pipeline, and facility fluid sampling programs for geothermal brine, condensate, non-condensable gases, and reinjection fluids in accordance with established SOPs
• Perform on-site measurements including pH, temperature, conductivity, dissolved oxygen, and flow parameters
• Collect and properly preserve samples for off-site laboratory analysis, maintaining chain of custody and sample integrity
• Operate and maintain field sampling equipment including two-phase separators, gas collection apparatus, and portable analytical instruments

Data Collection & Reporting

• Maintain accurate field logs, sampling records, and chain-of-custody documentation for all geochemical activities
• Enter field and laboratory data into tracking systems accurately and on schedule
• Identify and escalate out-of-specification results or anomalous trends to the Geochemical Engineer
• Support preparation of routine monitoring reports and data summaries

Chemical Treatment Support

• Support on-site operation and monitoring of chemical injection systems including scale and corrosion inhibitor dosing
• Assist with installation, retrieval, and evaluation of corrosion coupons and monitoring probes
• Maintain chemical inventory records and support safe handling, storage, and disposal of treatment chemicals in compliance with site safety and environmental requirements

Cross-Functional Field Support

• Coordinate sampling activities with plant operations to minimize interference with production
• Support commissioning-phase geochemical baseline programs at new Fervo facilities
• Assist the Geochemical Engineer with field execution of specialized sampling campaigns, equipment tests, and treatment trials

Required Qualifications

• Associate's or Bachelor's degree in Chemistry, Geology, Environmental Science, or related technical discipline, or equivalent hands-on experience in a field chemistry or laboratory technician role
• 2+ years of experience in field sampling, water chemistry, or laboratory analysis in an industrial, energy, or environmental setting
• Familiarity with chemical safety protocols, PPE requirements, and safe handling of corrosive or hazardous materials
• Strong attention to detail and commitment to data accuracy and documentation discipline
• Ability to work independently in a field environment and communicate clearly across technical and operational teams
• Willingness to travel to Fervo plant sites; this is a field-forward role with regular site presence required

Preferred Qualifications

• Experience with geothermal, oil and gas, or industrial process fluid sampling
• Familiarity with brine chemistry, scaling indices, or corrosion monitoring programs
• Experience operating chemical injection or inhibitor dosing systems
• Exposure to geochemical modeling or laboratory analytical methods (ICP-MS, titration, ion chromatography)

Work Schedule & Location 

• Non-exempt position with a standard 5/2 work schedule, on-site supporting Fervo’s geothermal field operations near Milford, Utah
• Candidates must be located within a commutable distance of the Milford field site.
• Regular field presence required, with site visits multiple times per week during normal operations.
• Daily field work expected during installations, commissioning, and active monitoring periods.
• Work primarily performed outdoors in field environments.
• Occasional travel to Fervo offices in Golden, Colorado and Houston, Texas for training, coordination, and project support.
• Work outside standard business hours or on weekends may be required during critical operational periods.
