Allometrics technician at the calibration bench — apprentice-to-credentialed-lead training pipeline
A trade you can grow inside — apprentice to credentialed lead, field and bench, with formal accreditation training as part of the job

The trade we hire and train for

Allometrics is built around a credentialed technical workforce. The work is part field service (driving to a customer site, working in a refinery I&E shop, a hospital pharmacy IV room, a biotech BSL-2 lab, or a polymer plant QC bench) and part bench work (the climate-controlled Mass / Dimensional / Temperature lab in our Webster, TX building).

Most of our long-tenured technicians started as apprentices. The path runs:

  • Apprentice Technician (Level 1) — entry into either the calibration discipline or the controlled-environment certification discipline. Paid training. Formal mentorship.
  • Calibration Technician or CE (Controlled Environment) Technician — independent execution under supervision, growing scope of work, building toward formal credentials.
  • Field Lead Technician — runs onsite work independently, mentors apprentices on the job, owns customer relationships.
  • Technical Lead — full credentialed expert in a discipline (CE Technical Lead, Biosafety Technical Lead, Calibration Technical Lead). The senior bench of the company.

The credentials we sponsor and pay for as part of the job:

  • CETA Registered Cleanroom Certification Professional (RCCP) — the professional credential for cleanroom certification.
  • NSF Accredited Technician — the professional credential for biosafety cabinet and pharmacy primary engineering control work.
  • NSF/ANSI 49 Field Certifier — the BSC-specific certification credential.
  • NEBB-credentialed TAB technician — air balancing and HVAC TAB credential (sister company Precision Biotech Solutions).
  • ISO/IEC 17025 method-specific qualifications for calibration disciplines.

If you have these credentials already, you'll work somewhere they're treated as the baseline — not the ceiling. If you don't have them, the path to earning them is built into the role.

Allometrics cleanroom certification technician at a hospital pharmacy — CETA-RCCP and NSF credentialed work in a regulated environment
Apprentice Technician (Level 1) — paid training into either the calibration or the controlled-environment certification path

Apprentice Technician (Level 1)

The role: Entry-level, paid training position. Apprentices work alongside credentialed technicians on real customer jobs from week one — calibrating instruments at our Webster bench, traveling onsite for cleanroom recertifications, supporting biosafety cabinet certification, learning the procedures that lead to formal credentials.

Two tracks:

  • Calibration apprentice — learn the metrology disciplines (mass, dimensional, pressure, temperature, electrical, volumetric, environmental). The work is detail-oriented bench and field calibration under ISO/IEC 17025 procedures.
  • Controlled Environment apprentice — learn cleanroom certification, biosafety cabinet certification, fume hood certification, and the field-service work that supports USP <797> pharmacies, cGMP manufacturing, and BSL-2/3 research.

What we look for: Mechanical aptitude. Comfort with detailed documentation (calibration is half measurement, half record-keeping). Customer-facing demeanor — most of the work happens at customer sites where you represent Allometrics. Reliable transportation. Willingness to travel within the southern U.S. region for field work. No specific degree required — we've trained career technicians from a wide range of backgrounds.

What you grow into: Independent technician within 12–24 months, leveraging on-the-job training, formal credentials, and direct mentorship from senior technical leads.


Allometrics CETA-RCCP technician performing cleanroom recertification at a regulated customer facility
Cleanroom Certification Technician (CETA-RCCP / NSF Accredited Technician) — the field-service backbone of the controlled-environment program

Cleanroom Certification Technician (CETA-RCCP / NSF)

The role: Performs annual and semi-annual recertification of ISO Class 5/7/8 cleanrooms — particle counts, air change rate verification, pressure cascade testing, recovery testing, dynamic smoke studies, HEPA integrity testing, T/RH validation. Customer sites include hospital pharmacies, 503A and 503B compounding pharmacies, cGMP manufacturing, cell & gene therapy cores, biotech R&D operations, and BSL-2 / BSL-3 research labs.

Credentials we sponsor: CETA Registered Cleanroom Certification Professional (RCCP), NSF Accredited Technician for primary engineering controls (BSCs, LAFWs, CAIs, CACIs), and NSF/ANSI 49 Field Certifier for biosafety cabinet certification.

What we look for: Existing technicians with CETA-RCCP or NSF credentials, OR experienced technicians ready to earn them. Strong field-service background. HVAC and instrumentation familiarity helpful. Comfort working in regulated environments — cGMP cleanrooms, hospital pharmacies, BSL-3 labs — where everything is documented and every report is read by an auditor.

What it pays into: Direct path to Technical Lead roles. Senior CE Technical Lead is one of the most credentialed and best-compensated technical positions at the company.

Already CETA-RCCP or NSF credentialed?

You'll work somewhere those credentials are the baseline expectation — and where the work has 50 years of customer relationships behind it.

Allometrics calibration technician at the climate-controlled Webster bench — ISO/IEC 17025 calibration work
Calibration Technician — bench work in our climate-controlled Mass / Dimensional / Temperature lab, plus onsite field service across the Gulf Coast

Calibration Technician

The role: Performs accredited calibration work across the disciplines on our published A2LA scope — mass, dimensional, pressure, temperature, electrical, volumetric, environmental. Mix of bench work (in our Webster, TX climate-controlled lab) and field service (at customer sites — refineries, hospitals, biotech labs, university research, polymer plants).

Disciplines we calibrate: mass and weighing (Class F field standards through Class 0 lab standards), dimensional (calipers, micrometers, gauge blocks, indicators, surface plates), pressure (process gauges, dead-weight testers, transmitters), temperature (thermocouples, RTDs, dataloggers, thermal imagers), electrical (multimeters, oscilloscopes, process loop calibrators, insulation testers), volumetric (single- and multi-channel pipettes, burettes, dispensers per ISO 8655), environmental (humidity, mapping, IAQ).

What we look for: Existing calibration technicians (any discipline — most generalize over time). Strong measurement-and-uncertainty mindset. Documentation discipline (ISO/IEC 17025 lives in the records). Customer-facing comfort for onsite work. Willingness to travel within the southern U.S. region.

What it pays into: Calibration Technical Lead. The senior bench of the cal program.

Field Lead Technician — runs onsite work, mentors apprentices, owns customer relationships
Field Lead Technician — owns the onsite work, mentors apprentices, runs customer relationships

Field Lead Technician + Technical Lead roles

The senior bench. Field Lead Technicians run multi-day onsite engagements independently, mentor apprentices in the field, and own ongoing customer relationships. Technical Leads (CE Technical Lead, Biosafety Technical Lead, Calibration Technical Lead) are the credentialed experts the rest of the company escalates to — they sign off on complex jobs, train the team, and represent Allometrics in front of inspectors and auditors.

These roles open up regularly as the company grows. Most are filled internally from the apprentice → tech → Field Lead pipeline, but external candidates with the right credentials are always welcome.
