Reservoir Engineer (Carbon Storage)

Location: Fort Lupton, Colorado, United States; Workplace: On-site

Company

hirify.global develops bio-oil sequestration and carbon removal projects, with locations in San Francisco, Colorado, and Louisiana.

What you will do

• Draft, assemble, and steward Class V UIC permit applications for EPA regional and state programs.
• Build and maintain injection strategies, reservoir models, analytical tools, and injection forecasts.
• Monitor reservoir response using pressure data, tracer surveys, and formation logs, identifying anomalies and potential migration risks.
• Optimize injection rates, protect formation integrity, and evaluate opportunities to improve efficiency or expand injection footprints.
• Plan subsurface studies, field data collection, formation characterization, and laboratory projects with subsurface, land, operations, and materials science teams.
• Assess reservoir uncertainty, injectivity decline, pressure limits, mechanical constraints, and end-of-life risks for individual wells and portfolios.

Requirements

• 5+ years of reservoir or subsurface engineering experience in injection or disposal, EOR, carbon storage, or reservoir management.
• Degree in petroleum engineering, chemical engineering, geoscience, or a closely related field.
• Hands-on experience with reservoir modeling, forecasting, pressure-transient behavior, petrophysics, and formation characterization.
• Working knowledge of UIC permitting, including Class I, Class II, or Class VI applications, area-of-review analysis, or pressure and plume modeling narratives.
• Strong technical writing and stakeholder communication skills for working with regulators, finance, consultants, and cross-functional teams.
• Ability to travel as needed to support operations, well development, and permitting.

Nice to have

• Direct carbon storage or Class V/Class VI injection experience.
• Experience with pressure-transient, step-rate, tracer, or mechanical integrity tests.
• Familiarity with pore space, mineral rights, well bonding, and injection project land or regulatory interfaces.
• Experience with CMG, Petrel, Kappa, reservoir simulation, or subsurface data and analytics workflows.
• Experience in a lean or early-stage operating environment.
