Job Description   Are you ready to lead Gilead’s next chapter as we design and establish our biologics manufacturing footprint in Foster City, CA?    Gilead Sciences is seeking exceptional, hands-on technical experts in Biologics Drug Substance Single-Use GMP Manufacturing who thrive at the intersection of strategy, technical innovation, and real-world execution.    In this role, you will execute critical elements of the design, startup, and operation of a new, state-of-the-art Single Use DS Biologics Manufacturing facility in Foster City. This is a rare opportunity to help build a facility from the ground up—while also being on the floor ensuring the solutions you develop truly work. This role is intentionally designed as a hybrid technical and execution role, with presence on the manufacturing floor to directly impact operations and continuously translate real‑world experience into improved processes, documentation, and strategy.     This highly dynamic role requires:  • Deep technical experience within biologics DS operations and single‑use technologies 

• A builder’s mindset—comfortable shifting between long‑range strategy and detailed, hands‑on execution 

• Collaboration across cross‑functional project, engineering, Quality, and operations teams 

• Adaptability and ownership, with a willingness to take on whatever is needed to successfully start up and run a new facility 

• Integrity, commitment to cGMP compliance, and a commitment to always act in the best interests of our patients 

  You will alternate seamlessly between design decisions (facility, equipment, documentation, manufacturing strategy) and tactical GMP execution during startup and ongoing operations. This role is ideal for technical experts who want to both architect the future, actively bring it to life, and support its ongoing operation.    We’re seeking trailblazers—collaborative, action‑oriented technical experts who are energized by complex problems, motivated by building new capabilities, and driven to leave a legacy through their solutions and the knowledge they share.    Key Responsibilities: As a key technology and operations expert, you will shape the design of Gilead’s new Foster City Biologics Drug Substance manufacturing plant, then start up and operate the plant for ongoing cGMP manufacturing. Your responsibilities will include:  

Manufacturing Execution and Startup Ownership   • Support first time execution readiness for unit operations, systems, and workflows. Perform dry runs, engineering runs, and end-to-end execution walkthroughs to identify gaps prior to GMP go-live. 

• Act as a technical first responder during campaigns to stabilize operations and resolve issues in real time. 

• Directly execute and document key operations on the plant floor in full compliance with cGMP expectations. 

• Execute full‑scale process and equipment validation studies. 

• Stay current on industry best practices in single‑use biologics manufacturing and champion adoption within Gilead. 

GMP Facility Startup and Equipment/Process Design Input   • Provide manufacturing end-user input to facility, equipment, and automation design decisions. 

• Support implementation and manufacturing workflow development for the startup of digital manufacturing and data solutions in collaboration with automation, engineering, and information technology teams. 

• Participate in and support risk assessments and startup readiness activities for new equipment, processes, and workflows. 

• Partner with Technical Development to provide manufacturability input on process platforms, and include new process requirements into equipment, automation, and documentation updates. 

Operational Excellence, Digital Innovation, and Cross-Functional Leadership   • Develop innovative, intuitive, and pragmatic solutions to complex technical challenges. 

• Identify and implement process improvements to increase yield, optimize capacity, improve operational efficiency, reduce costs, enhance compliance, and ensure safety 

• Compliantly apply AI tools to enhance productivity for yourself and the team. Identify opportunities to develop specialized AI tools and digital manufacturing solutions within your area of technical expertise. 

• Represent Foster City Manufacturing as a member of cross-functional project teams.
