CMT Field Technician
Field technicians are the front line of construction materials testing. You will sample fresh concrete, run slump, air, temperature, and cylinder sets, verify soil compaction with a nuclear density gauge, and document every result the same day. No experience required for entry level: we train and we pay for your certifications.
What you'll do
- Sample and test fresh concrete per ASTM C172, C143, C231, C1064, and C31
- Run field density and moisture tests per ASTM D6938
- Prepare clear daily field reports tied to placement locations
- Maintain gauge standardization, cure boxes, and chain of custody
- Communicate results to superintendents on the spot
What we're looking for
- Valid driver's license and clean driving record
- Comfortable outdoors in Gulf Coast heat and winter sites
- Reliable, detail-first, and coachable
- ACI Field Grade I and nuclear gauge certification a plus — we sponsor both
What a week in this job looks like
Most mornings start with a dispatch text the night before: which site, which tests, which spec. You load the truck, standardize your nuclear gauge against its reference block, check your cure boxes, and roll. By mid-morning you might be running density tests on a lift of select fill; by afternoon you are at a different site sampling concrete off the chute, running slump, air, and temperature, and casting cylinders while the superintendent watches the clock.
The work is outside, it is physical, and it matters. A pad you test this month carries a building for fifty years. You will learn to read a jobsite, talk to superintendents twice your age, and defend a failing test without flinching, because the number is the number.
Certifications, training, and where this leads
You do not need certifications to start. You need to show up, take notes, and care whether the result is right. We put new technicians through structured field training with a senior tech, then sponsor ACI Concrete Field Testing Grade I, nuclear gauge safety certification, and NICET Level I and II as you progress. Every certification you earn is paid for by the company and belongs to you.
The ladder from here is real: Field Technician to Senior Field Technician and Special Inspector, into laboratory, project management, or drilling oversight depending on where your strengths land. Most of the people running this industry started exactly where this posting starts.
Pay, schedule, and travel
Pay runs $18 to $28 per hour depending on experience and certifications, and field positions are hourly with overtime when production schedules run long, which in this business they do. Big pours start early; earthwork seasons run hot; your paycheck reflects both.
Texas positions dispatch through our Sugar Land operations hub and work sites across their metro. Positions outside Texas support defined project programs, staffed on a project basis, with travel assignments and per-diem arrangements set out clearly before you commit to a deployment.
Safety, quality, and the standards we work under
You will operate a nuclear density gauge, which means you will be trained, badged, and monitored under a licensed radiation safety program, no exceptions and no shortcuts. Personal protective equipment, jobsite safety orientation, and pre-task planning are part of the job, not an interruption to it.
Every result you record lives inside a documented quality system built to AASHTO R18, with laboratory backup behind your field calls. When your name is on a report, the system behind it holds up.
How hiring works, and our commitment
Apply through this page, with a resume, a link, or just your work history in the box. If there is a fit, expect a phone call within a few business days, a straightforward conversation about the work, verification of any certifications, and an offer that matches what this posting says. Field positions require a valid driver's license with an acceptable record, the ability to lift and carry testing equipment on active jobsites in outdoor conditions, and pre-employment screening consistent with jobsite and radiation-safety requirements.
We are an equal opportunity employer. Every applicant is considered without regard to race, color, religion, national origin, age, sex, sexual orientation, gender identity, disability, or veteran status. What we care about is whether you will get the number right and stand behind it.

The listed range is $18–$28 / hour, set by certifications held, years of documented field or laboratory experience, and the hub's market. Certified candidates enter above the bottom of the range.
What certifications matter most for a CMT Field Technician?
ACI Concrete Field Testing Technician Grade I is the baseline for anyone touching fresh concrete; NICET Construction Materials Testing (Soils, Concrete, Asphalt) levels and ICC special inspector certifications raise both scope and pay. Certifications earned on the job are paid for by the company and belong to you.
Which ASTM tests does a CMT Field Technician run?
Fresh concrete: ASTM C172 sampling, C143 slump, C231 air content, C1064 temperature, C138 unit weight, and C31 cylinder casting. Earthwork: ASTM D6938 nuclear density and moisture against the D698 or D1557 Proctor. Aggregate sampling per ASTM D75. Specimens and daily reports return to the laboratory at the end of the day.
