job purpose:  

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. 

responsibilities:

Manufacturing technical leadership, Operational Support and Troubleshooting 

  • 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. 

Process design, scale-up, and optimization 

  • 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. 

Technical Advocacy

  • 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. 

Milk chemistry, physical chemistry, and product quality 

  • 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). 

Analytics & data-driven decision making

  • 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

People leadership 

  • 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. 

 

skills/qualifications required:  

  • 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 packaging interactions (commercial aseptic operations strongly preferred). 
  • Track record of leading cross-functional root-cause investigations (e.g., flavor defects, oxidation, shelf-life failures, stability issues). 
  • Experience in capital projects preferred. 
  • Familiarity with regulatory expectations and operator training frameworks for pasteurization systems preferred.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
