Materials Process Engineer Jobs in Virginia (NOW HIRING)

Thermo Fisher Scientific’s Clinical Diagnostic Reagents (CDR) group is seeking a Process Engineer II to support the design, optimization, validation, and lifecycle management of purified water systems, chemical formulation processes, and sanitary fluid-handling equipment used in clinical diagnostic reagent manufacturing.

This role provides technical engineering support and leadership for high-purity water generation, storage, and distribution systems, as well as chemical formulation processes and associated equipment, including filtration systems, piping, pumps, valves, instrumentation, and mixing systems. The position operates within a cGMP, FDA-regulated, and ISO 13485 environment.

The Process Engineer II will lead or support mechanical and process design initiatives, manufacturing reliability and throughput improvements, and capital projects from concept and feasibility through commissioning, qualification, sustainment, and end-of-life management. The engineer will collaborate closely with Operations, Facilities, Quality, Validation, R&D, and other cross-functional partners to deliver successful engineering projects.

The role will also support the performance of high-volume, high-mix manufacturing operations with equipment spanning varying levels of automation. The engineer will contribute to measurable improvements in Overall Equipment Effectiveness (OEE), First Pass Yield (FPY), scrap, cycle time, changeover time, and equipment uptime while managing multiple engineering priorities and projects.
