Our mission is to transform geothermal into America’s most dependable and affordable source of clean, around-the-clock power. By combining innovations in horizontal drilling, fiber-optic sensing, and advanced reservoir engineering, Fervo has developed a repeatable approach to building utility-scale enhanced geothermal systems. Our flagship Cape Station development in Utah is planned to deliver 500 MW of firm, carbon-free power, and we are advancing a development pipeline of more than 50 GW. Join us and work alongside world-class engineers, geoscientists, operators, project builders, and business leaders working to make geothermal a cornerstone of a more reliable, affordable, and sustainable energy future.\nPosition Description\nFervo is seeking a Seismologist to lead the design, deployment, and processing of surface and borehole seismic monitoring networks across our EGS development portfolio. You will own our arrays of three-component geophones and broadband seismometers - sited at the surface, in shallow vaults and boreholes, and downhole in monitoring wells - from network geometry and instrumentation through calibration, data quality, and continuous processing.\nThe central deliverable of this role is a high-precision, defensible earthquake catalog. Proficiency with HypoDD and GrowClust is required, and you will build, relocate, quality-control, and defend the catalogs that feed fracture-network characterization, reservoir models, induced-seismicity mitigation protocols, and regulatory and community engagement.\nFervo also operates fiber-optic Distributed Acoustic Sensing (DAS) in a number of wells, and you will incorporate DAS alongside the conventional sensor network as a complementary observing system. Familiarity with DAS is valuable, but it is not the focus of the role and is not required at hire - the conventional network and the relocated catalog come first.\nResponsibilities\nSurface and Borehole Geophone & Seismometer Networks\nDesign, deploy, and maintain surface and borehole geophone and seismometer networks.\n\nSet network geometry and instrumentation to meet detection, location-accuracy, and completeness targets.\n\nOwn instrument response, sensor orientation and calibration, timing, and continuous data QC.\n\nRun automated detection, phase picking, and event association across the network.\n\nBuild and maintain 1D and 3D velocity models and station corrections.\n\nManage field campaigns, vendor scopes, and data-delivery standards.\n\nEarthquake Location, Relocation, and Catalog Development\nRun HypoDD for double-difference relocation.\n\nRun GrowClust for relative relocation and hierarchical clustering.\n\nGenerate waveform cross-correlation differential travel times and maintain automated relocation pipelines.\n\nDetermine source parameters - magnitude, focal mechanism, moment tensor, and stress drop.\n\nInterpret relocated seismicity as fracture geometry, stimulated volume, and fault reactivation.\n\nMaintain a versioned production catalog with documented magnitudes, completeness, and uncertainty.\n\nDistributed Acoustic Sensing (DAS) - complementary observing system\nIncorporate DAS data from instrumented wells alongside the conventional network.\n\nPerform joint DAS and sensor processing where it improves the catalog.\n\nInterpret DAS response in a borehole setting, including its resolution limits.\n\nInduced Seismicity, Hazard, and Risk\nTrack b-value and magnitude of completeness, and forecast seismicity rates and maximum magnitude.\n\nDevelop real-time hazard algorithms using physics-based, statistical, and machine-learning methods.\n\nMaintain traffic light protocols and mitigation strategies with operations.\n\nLink observed seismicity to Thermo-Hydro-Mechanical-Chemical reservoir models.\n\nRepresent Fervo with regulators, partners, and communities on induced-seismicity questions.\n\nQualifications\nRequired\nPh.D. in Geophysics, Seismology, Applied Mathematics, or a closely related field. No minimum years of industry or post-doctoral experience are required - recent and upcoming graduates are encouraged to apply.\n\nWorking proficiency with HypoDD and GrowClust, including generation of waveform cross-correlation differential travel times, parameter selection, and assessment of relocation uncertainty. This may have been developed through thesis work, post-doctoral research, or industry practice.\n\nSolid grounding in surface and borehole seismic monitoring - network geometry and detectability, instrument response, sensor orientation and calibration, and earthquake detection, picking, and location.\n\nKnowledge of earthquake source analysis, including moment tensor inversion, focal mechanism determination, magnitude estimation, and stress drop estimation.\n\nUnderstanding of induced seismicity and seismic hazard concepts - magnitude of completeness, b-value, Gutenberg-Richter statistics, and ground-motion estimation.\n\nPython proficiency for seismic data processing (ObsPy, NumPy, SciPy, pandas, or equivalent tooling) and comfort working in Linux environments with shell scripting and version control.\n\nAbility to build velocity models and to produce, quality-control, and defend earthquake catalogs that others rely on.\n\nWillingness to travel to field sites for network deployment, commissioning, and troubleshooting up to 20%.\n\nPreferred\nHigh Performance Computing and large-scale distributed processing of continuous seismic data.\n\nMachine learning applied to seismological problems, including deep-learning phase pickers.\n\nLocation\nFervo Energy has offices in Houston, TX, Golden, CO, Reno, NV, Oakland, CA, and Salt Lake City, UT. This position will be eligible for some hybrid work flexibility, but regular in-office presence at any of the above locations will be required.\nBenefits & Perks\nFervo offers a comprehensive benefits package designed to support your health, financial well-being, and life outside of work. Benefits for eligible employees include:\nMedical, dental, and vision plan options\nEmployer-paid basic life insurance and short-term and long-term disability coverage\nA 401(k) plan with up to 6% match\nFlexible paid time off and paid parental leave\nFamily-building, fertility, hormonal health, pregnancy, postpartum, and parenting support through Carrot\nA dependent care FSA for eligible child and elder care expenses\nAn annual Lifestyle Spending Account for eligible wellness expenses, including fitness, financial planning, pet insurance, and pet care\nEmployee ownership opportunities through Fervo’s Employee Stock Purchase Program, as well as stock option grants and bonus opportunities for eligible roles\nBenefits and programs are subject to eligibility requirements and may change.\nOur Workplace\nFervo Energy highly values having employees work in the office to foster collaboration and strengthen our company culture. This role follows a hybrid schedule, with team members expected to work in the office three days per week. Fervo considers this in-office schedule an essential function of the role. Your recruiter can share more information about the schedule.\nEqual Opportunity Employer\nFervo Energy is an Equal Opportunity Employer and does not discriminate on the basis of race, color, creed, gender, religion, marital status, registered domestic partner status, age, national origin, ancestry, physical or mental disability, medical condition, sex, genetic information, sexual orientation, military or veteran status, or any other consideration made unlawful by federal, state, or local law.
