How Will You Make an Impact?

Our new Bioprocess Design Center is an innovative facility dedicated to demonstrating and training customers on our innovative single-use technologies, Upstream and Downstream solutions, cell culture media, cell lines, resin and analytical offerings. We are seeking a cell culture engineer who drives customer-centric process innovation by designing, executing, and delivering upstream process development programs that generate data-driven evidence of single-use technology (SUT) performance. This role bridges Thermo Fisher's product portfolio with real-world customer applications — advancing confidence in our technologies through evidence generation, customer process optimization, hands-on training, and internal enablement.

The position plays a critical role in building technical credibility with customers, ensuring our bioprocessing solutions are validated through rigorous experimentation and well-documented performance metrics. This individual also supports small-scale process development up to 5,000L scale. The role leads customer training initiatives and supports internal capability building on Thermo Fisher's SUT platforms.

What Will You Do?

• Design and execute cell culture studies to replicate and optimize customer bioprocess workflows using Thermo Fisher SUT equipment (e.g., bioreactors, mixers, and harvest systems).
• Develop technical data packages demonstrating process robustness, scalability, and product performance across a range of customer applications.
• Generate scientifically defensible evidence for product claims and marketing collateral, aligned with BDC goals for evidence generation and customer adoption.
• Collaborate with Application Scientists and R&D to feed experimental data back into product development and next-generation technology design.

• Lead and deliver hands-on customer training sessions focused on best practices in SUT operation, upstream process control, and data analytics.
• Translate complex technical concepts into practical training modules for both internal and external stakeholders.
• Partner with commercial teams to support customer visits, technology showcases, and pilot demonstrations that strengthen confidence in Thermo Fisher solutions.

• Conduct internal training programs for Thermo Fisher colleagues, focusing on the application, troubleshooting, and process design aspects of SUT bioprocessing technologies.
• Mentor junior engineers and scientists, fostering a culture of technical excellence and operational readiness within the BDC.
• Provide cross-functional guidance on experimental design, data interpretation, and single-use process integration.

• Contribute to the design of next-generation process solutions by integrating feedback from BDC studies into product and system development.
• Lead initiatives that showcase end-to-end workflows combining upstream, harvest, and analytical tools within the Thermo Fisher ecosystem.
• Partner with global R&D, marketing, and operations teams to define experimental priorities aligned with customer needs and market trends.

Competencies

• Deep technical knowledge of single use bioreactor operation (5L-5000L scale), control strategies, and process data analysis.
• Proven ability to generate and communicate technical evidence supporting product performance.
• Strong communication skills with experience leading customer-facing technical sessions.
• Adept at designing experiments that align with measurable business KPIs (e.g., number of customer engagements, process validations, internal training sessions, and data packages generated).
• Comfortable working in a fast-paced, matrixed environment with cross-functional teams.

How Will You Get Here?

• B.S. in Chemical/Biochemical Engineering, Biotechnology, or related discipline with ≥5 years of relevant experience; M.S. with ≥3 years; or PhD.
• Strong background in mammalian cell culture, upstream bioprocessing, and SUT system implementation.
• Demonstrated experience designing and executing process development or scale-down studies.
• Familiarity with data analytics, process automation, and technology transfer principles.
