The Sr. Dairy Processing Engineer will come in with deep technical expertise in fluid milk membrane separations (especially ultrafiltration), thermal processing (HTST/HHST/UHT), and end-to-end milk unit operations—from raw milk receiving through packaging. This role is a hands‑on technical authority who will be integral to process technology innovation as well as troubleshooting manufacturing issues, optimizing process capabilities and product quality, supporting pilot-to-plant scale‑up, and serving as a trusted partner to Operations, Manufacturing, and Quality.

• Serve as a go‑to technical expert for fluid milk separation, standardization, homogenization, pasteurization systems (HTST/HHST/UHT), and packaging performance.
• Diagnose and resolve process and product issues.
• Partner with Operations/Manufacturing/Quality to drive safe, compliant, and reliable production and troubleshoot process deviations, and identify root causes for quality issues.

• Define critical process parameters, key performance indicators, and control plans.
• Design, coordinate, and execute pilot and commercial‑scale plant trials.
• Own process capability improvements and provide technical input to capital projects and equipment selection.
• Provide subject‑matter expertise on OEM platforms and engineering approaches.

• Proactively identify opportunities for process optimization that improve efficiency, sustainability, yield or product shelf‑life.
• Lead initiatives and manage stakeholders across Engineering, Quality, and Supply Chain.

• Apply deep knowledge of milk composition and how processing impacts chemistry, physical properties, and functional performance of milk and its components.
• Partner with Product Development and Operations on formulation/processing choices for fluid dairy products, including shakes and other forms (sensory, taste, texture, stability, shelf‑life).
• Define plans and execute and interpret analytical testing results tied to processing and shelf‑life: milk composition chemistry, rheology, chromatographic/volatile profiling and other relevant analytical methods.
• Establish and improve SOPs, troubleshooting playbooks, and process data reviews.

• Individual contributor to start. Will build and develop a team of 1–4 (e.g., process engineers, dairy scientists, technicians).
• Build strong cross‑functional relationships and communicate clearly from plant floor to leadership level.

• MS in Dairy Science, Food Engineering, Food Science, Chemical Engineering, or closely related field with a focus on dairy processing and/or thermal processing.
• 5–10 years of progressive experience in fluid dairy processing spanning pilot through commercial manufacturing.
• Demonstrated expertise in:
  • HTST/HHST and/or UHT processing of fluid milk (and/or cream) and practical plant troubleshooting.
  • End‑to‑end milk unit operations: raw receiving → clarification/separation → standardization → homogenization → pasteurization/aseptic processing → packaging.
  • Ultrafiltration of milk and/or dairy membrane separations (MF/UF/NF/RO familiarity as a plus).
• Strong technical competence in dairy physical chemistry and processing impacts on proteins/fats/enzymes.
• Proven ability to partner with Operations/Manufacturing/Quality in a high‑accountability environment.
• Experience with aseptic systems and…
