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 own and directly 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 across 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 strategic design decisions (facility, equipment, documentation, manufacturing strategy) and hands-on 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.

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

• Plan and 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.

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 cost, 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 providing guidance, insight, and recommendations.

• Exemplify Gilead’s Core Values—integrity, inclusion, teamwork, excellence, accountability.

• Demonstrate the Gilead Leadership Commitments as a visible technical leader: I AM BOLD, I CARE, I LISTEN, I TRUST, and I OWN.

GMP Documentation, Quality, and Compliance

• Translate process design and engineering documentation into clear, executable operational SOPs, work instructions based on hands-on execution during startup.

• Author and review GMP documentation (SOPs, work instructions, batch records, automation recipes, training materials, validation protocols/reports).

• Initiate, investigate, resolve, and support CAPAs for GMP deviations within your areas of expertise.

• Support Quality Risk Management (QRM) activities, ensuring balanced and science‑based Quality and Compliance decisions.
