+ Conduct daily wastewater testing and document results
+ Provide excellent internal customer service and support
We operate with a safety-first mindset—always. You’ll uphold essential safety practices such as lockout/tagout, confined space entry, proper PPE use, ladder safety, GMPs, food defense procedures, and more.

You’ll thrive in this role if you are mechanically inclined, detail-oriented, and committed to getting the job done right the first time. Ideal candidates bring:
+ 2–5 years of maintenance mechanic experience
+ High School Degree or equivalent
+ Knowledge of electrical circuits, safety codes, food plant safety standards, and NFPA 70e
+ Experience with computers and microprocessor systems (Microsoft Word & Excel preferred)

When you join us, you’ll enjoy:
+ Above-market wages
