Qualifications

A university degree in an engineering discipline is required unless the candidate has extensive previous work experience in a comparable role. A degree in chemical or environmental engineering is preferred, while a degree in mechanical or industrial engineering is also suitable.

6+ years of experience supporting sanitary crossflow membrane systems in an applications or process engineering role is required

Subject matter expertise in at least one of the following fields:

Design and operation of a dairy processing facility

Design and operation of industrial water treatment with spiral UF membranes

Design and operation of food process membrane systems (sanitary RO/NF/UF)

Broad and detailed working knowledge of non-membrane process technologies, such as particulate filtration, evaporation/drying, etc.

High level understanding of process flows in a dairy processing plant

Expertise in fluid dynamic principles, especially with membrane processes

Knowledge of spiral element autopsy processes is an added benefit
