• Review and provide technical feedback on design documents (P&IDs, URS documents, schematics, drawings, models, technical data sheets) during quotation, custom system builds, technology transfers, and new product introductions.

• Manage creation, update, and release of manufacturing documentation (SOPs, work instructions, test procedures, batch records, bills of material, drawings, models, and system configuration documentation) through the Engineering Change process.

• Develop practical, application-based solutions for hardware integration, manufacturing flow, work cell build-out, test equipment definition, and process readiness.

• Train and support manufacturing personnel on new or revised processes, documentation, test methods, and system-build expectations.

• Support technology transfers from other Repligen sites to Marlborough Manufacturing, including build readiness, documentation gaps, fixture/test needs, training, and process stabilization.

• Identify, investigate, and resolve process, quality, and manufacturability issues for assigned products and processes, including support for customer issue investigations and corrective actions.

• Participate in the creation and maintenance of departmental best practices, standard work, and continuous improvement initiatives.

• Promote Repligen’s EHS culture by supporting safe work practices, identifying hazards or near misses, and participating in corrective actions and process improvements.

• Demonstrated project management capability. Including planning, prioritization, schedule development, action tracking, risk escalation, and execution through cross-functional teams.

• Strong cross-functional communication skills with the ability to lead, influence, and align internal and external stakeholders.

• Strong electro-mechanical aptitude with demonstrated ability to understand, troubleshoot, and improve complex hardware, systems assemblies, mechanical interfaces, electrical components, fluidic systems, and test setups.

• Familiarity with process and design documentation (P&IDs, URS documents, schematics, drawings, technical data sheets, work instructions, SOPs, batch records, and bills of material).

• SolidWorks experience with component and assembly drawings preferred.

• Experience with hardware and systems design/assembly, fluidic testing, sheet metal fabrication, machined metal/plastic parts, fixture design, or test equipment selection preferred.

• Able to work with outside vendors, define technical requirements, follow up on assigned work, and manage deliverables to project needs.

• Excellent presentation, verbal, written communication, organization, and follow-through skills.

• Self-starter with the ability to operate with urgency, ownership, and sound judgment in a dynamic manufacturing environment.

• Process improvement experience.

• Data analysis/visualization skillsand familiarity with systems such as SAP are preferred.

• Demonstrated commitment to safety, PPE requirements, safe work practices, and leading by example in alignment with Repligen R-Values.
