Entry- to Mid-Level Hydrogeologist / Geologist
R. W. Harden & Associates, Inc. (RWH&A) is seeking a talented and motivated hydrogeologist / geologist with 0 to 5 years of experience for full-time employment in Austin, Texas. Since 1972, RWH&A has provided hydrogeologic consulting services primarily related to the evaluation of aquifer systems and the effective and efficient development of groundwater resources throughout Texas. RWH&A staff work on a variety of projects in diverse hydrogeologic settings for municipal, private, industrial, and regulatory clients. We are seeking a qualified candidate with strong interpersonal, organizational, and communication skills who is interested in developing practical experience in groundwater resource investigations, geologic interpretations, water well drilling and construction oversight, well and aquifer testing, and other field-based hydrogeologic projects. This is a field-oriented position that will require frequent travel and significant time at project sites throughout Texas. The successful candidate will work closely with RWH&A project managers and senior hydrogeologists and will be responsible for field observation, documentation, coordination, and oversight of drilling contractors and other field activities. Office responsibilities will include evaluation of field data, preparation of technical reports and figures, hydrogeologic analyses, regulatory support, and other project-related tasks.
Responsibilities
- Perform and coordinate field work associated with hydrogeologic investigations including exploration drilling and testing programs, and well construction projects.
- Provide field observation and oversight of drilling contractors during drilling, well construction, completion, development, rehabilitation, and/or testing/sampling activities.
- Coordinate field activities among contractors, RWH&A project managers, clients, laboratories, and other project personnel.
- Observe drilling operations and document drilling progress, methods, conditions, materials, equipment, and contractor activities.
- Collect, describe, and document drill cuttings and geologic samples, including preparation and maintenance of detailed lithologic and field logs.
- Observe and assist with geophysical logging and interpretation, well construction, casing and screen installation, cementing, well development, and other completion activities.
- Coordinate and perform aquifer testing, well-performance testing, groundwater level monitoring, and water quality sampling.
- Maintain accurate and detailed daily field reports, drilling records, photographs, test data, field notes, and project documentation.
- Provide field observation and documentation of construction activities to assist project managers in evaluating conformance with the Contract Documents, technical specifications, approved submittals, and applicable regulatory requirements.
- Review and become familiar with applicable plans, specifications, contract requirements, approved submittals, RFIs, and contractor work plans prior to and during field activities.
- Observe contractor activities and identify and promptly communicate apparent deviations, deficiencies, changed field conditions, or work that may not conform to the Contract Documents to the RWH&A project manager.
- Identify field conditions that differ from project plans or specifications and promptly communicate observations and potential issues to RWH&A project managers and senior staff.
- Communicate professionally with contractors, clients, regulatory representatives, and project personnel while appropriately referring to contractual interpretations, changes in scope, authorization of additional work, and other decisions requiring project-manager approval to senior staff.
- Research geologic and hydrogeologic data from federal, state, county, local, academic, and RWH&A records.
- Prepare technical memoranda and reports, including associated figures, maps, charts, tables, and field documentation.

Geologist Jobs in Texas: Frequently Asked Questions
How do you become a geologist in Texas?
To practice as a geologist in Texas, you must obtain a Licensed Professional Geoscientist (LPG) credential through the Texas Board of Professional Geoscientists. The board requires a bachelor's degree or higher in geoscience, a passing score on the ASBOG National Association of State Boards of Geology exam, and documented professional experience under a licensed geoscientist. Many Texas employers require or strongly prefer the LPG for any role that involves signing reports or advising on regulatory matters.
How much do geologists make in Texas?
Geologists in Texas earn a median of about $145,220 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $60,100 for the lowest 10% to over $287,180 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire geologists in Texas?
Employers hiring geologists in Texas right now include AECOM, EOG Resources, and JPMorganChase, based on current listings on Migrate Mate as of August 2026. Texas's concentration of independent and integrated oil and gas operators, along with environmental engineering firms serving TCEQ-regulated industries, means geologist openings appear across a wide range of company sizes and specialties.
Which Texas cities have the most geologist jobs?
Houston, Midland, and Plano have the most geologist openings in Texas. Houston dominates because it serves as the global headquarters for major integrated oil companies and a dense cluster of independents and oilfield services firms, while Midland drives strong demand through active Permian Basin operations and San Antonio attracts environmental and hydrogeology work tied to the Edwards Aquifer and nearby federal installations.
Are there remote geologist jobs in Texas?
Yes, but they're rare. About 42% of geologist openings tied to Texas are remote or hybrid as of August 2026, which reflects how much of the work involves field sampling, core analysis, or on-site regulatory compliance. The roles most likely to offer remote or hybrid schedules are those focused on subsurface data interpretation, GIS mapping, and technical report writing rather than active field work.
How can I get hired as a geologist in Texas with little or no experience?
The most realistic entry path is an internship or field technician role with an oil and gas operator or environmental consulting firm in Houston or Midland. Large Texas-based employers like ExxonMobil and Chevron run structured geoscience internship programs for students and recent graduates, and environmental firms working on TCEQ remediation projects regularly hire entry-level staff as environmental technicians or field samplers. Completing your ASBOG Fundamentals of Geology exam early and gaining GIS or Petrel software skills significantly strengthens a new-grad application.
Where can I find and apply to geologist jobs in Texas?
You can find and apply to geologist jobs in Texas on Migrate Mate, which lists current Texas openings across oil and gas, environmental consulting, mining, and public sector employers. Search the listings to see what is available right now, find roles that fit your background, and apply directly.
