Work Environment

This position is based in a fast-paced, small laboratory located inside a dairy manufacturing plant that produces both dairy and plant-based cultured products, including buttermilk, sour cream, heavy cream, ice cream, soft serve, yogurt mixes, conventional yogurt, strained Greek yogurt, dairy alternatives such as almond, coconut, and oat yogurt, as well as seasonal items like eggnog. The lab is functional but somewhat outdated and is not a clean room environment. The Lab Technician works closely with a small, friendly crew on 2nd shift who collaborate well and maintain a positive atmosphere. The regular schedule is Monday through Friday, 2:00 p.m. to 10:30 p.m., with openness to working one weekend day as needed. The role requires walking on the production floor to ensure compliance with GMPs and to collect samples, typically yogurt or milk-based products, including premium ice cream brands.
