Job description

Position Purpose

Reporting to the Horizon 2 Process Area System Owner, this FTE role provides long-term technical and system ownership for bulk purification processes and equipment supporting the US Ig Expansion program and the Kankakee manufacturing site. The position ensures process and equipment requirements are translated into compliant, operable, maintainable, and reliable designs and remain effective through design, installation, commissioning, qualification, process performance qualification, operational handover, and routine operation. The role serves as the subject matter expert for bulk purification unit operations, including chromatography, ultrafiltration/diafiltration, depth filtration, chemical virus inactivation, virus filtration, column packing, filter integrity testing, and associated single-use assemblies. The engineer provides technical leadership for scope definition, design reviews, vendor coordination, FAT/SAT, commissioning and qualification support, technical issue resolution, change control, deviation and CAPA support, process validation, continued process verification, lifecycle improvements, and knowledge transfer to site operations. The position works cross-functionally with Engineering, Automation, CQV, Validation, Tech Transfer, Quality, Regulatory, Production, Maintenance, Procurement, Construction, and external design and equipment partners.

The position requires periodic business travel to equipment vendors and other project locations, primarily to support Factory Acceptance Testing (FAT), technical reviews, and other project execution activities.
