Hands-on swabbing experience in a production or environmental monitoring context. Demonstrated ability to apply aseptic techniques and maintain sterility during sampling and testing. Experience in environmental monitoring programs within a food manufacturing or similar regulated environment. Proficiency with laboratory practices related to food microbiology, including sterility testing, bioburden assessment, and interpretation of microbiological data. Working knowledge of food safety principles and regulatory expectations, including alignment with FDA-related compliance for food manufacturing. Ability and willingness to spend significant time on the production floor (“boots on the ground”) to collect samples, perform investigations, and support operations. Strong analytical skills with the ability to conduct statistical analysis of large data sets and develop meaningful trend reports. Excellent communication skills to convey microbiological findings, risks, and recommendations to production, quality, sanitation, and corporate teams. Proven ability to lead investigations, implement corrective actions, and support continuous improvement in a manufacturing environment. Additional Skills & Qualifications Seafood HACCP training or certification is a plus. Experience designing, setting up, or managing a new microbiology laboratory is highly desirable. Prior experience managing or leading people within a laboratory or quality function is an advantage. Knowledge in food science or food safety programs, including environmental monitoring and pathogen control, is beneficial. Familiarity with developing, revising, and implementing SOPs, SSOPs, testing standards, and specifications within a GMP framework. Experience collaborating with external laboratories on test methods, result interpretation, and troubleshooting. Comfort working closely with cross-functional partners, including quality leadership, plant leadership, and corporate teams. Work Environment The role operates in both a laboratory and food production plant environment. The Microbiologist will help build and develop a microbiology laboratory, including contributing to layout, equipment selection, and process design, while also performing routine and investigative testing. The position requires frequent presence on the production floor to perform swab analysis, environmental sampling, and real‑time troubleshooting of microbiological issues. The work schedule is primarily a first‑shift role, generally Monday through Friday with core hours around 7:00 a.m. to 4:00 p.m., with some Saturdays as needed based on operational demands. While the position is first shift, there may be occasional requirements to come in during off shifts when urgent microbiological problems arise that need immediate testing and problem solving. The environment involves close collaboration with quality leadership, plant leadership, and corporate stakeholders. Standard food manufacturing and laboratory safety practices apply, including appropriate use of personal protective equipment and adherence to good manufacturing practices.
