About us
American Analytical (American Analytical Testing Laboratory Services / Black Labs, LLC) is a Tucson-based, ISO/IEC
17025:2017-accredited (ANAB AT-3321) and CDC ELITE environmental testing laboratory, and a Service-Disabled
Veteran-Owned Small Business (SDVOSB). We serve healthcare facilities, government and tribal health systems, and
manufacturers - with deep focus on Legionella and water-compliance microbiology, AAMI ST108 critical water for sterile
processing and dialysis, and a growing cosmetics microbiology program.
The role
We're hiring a part-time Microbiologist to support our growing microbiology bench - performing accredited
environmental and cosmetic microbiology testing, upholding ISO/IEC 17025 quality standards, and providing capacity for
peak workloads and scheduled bench coverage. This is a hands-on, on-site role, ideal for a detail-oriented microbiologist
who wants flexible part-time hours in a small, mission-driven accredited lab.
What you'll do
Perform Legionella culture testing per ISO 11731:2017 / CDC ELITE procedures - sample processing, plating, serial incubation reads through day 10, confirmation, and reporting.
Run heterotrophic plate count (SM 9215), total coliform & E. coli (SM 9223B), and related potable / non-potable water microbiology.
Support AAMI ST108 critical water and endotoxin (LAL) testing for sterile processing and dialysis water.
Contribute to the cosmetics microbiology program - microbial limits / USP <61>/<62>/<51> and Aerobic Plate Count (AOAC OMA 2015.13) on personal-care products - and environmental swab / clean-room monitoring.
Prepare and QC culture media, reagents, and controls; maintain rigorous aseptic technique.
Keep strict chain-of-custody and complete ISO/IEC 17025 documentation - bench sheets, QC records, traceability, and result entry in the LIMS.
Operate, calibrate, and maintain microbiology equipment (incubators, biosafety cabinet, autoclave, microscope); log maintenance.
Follow lab safety, biohazard, and waste-handling protocols.
Support method verification and proficiency testing (e.g., CDC ELITE panels) as needed.
Promptly flag nonconformances or out-of-specification results to the Laboratory Director.
