Sr Manufacturing Technical Expert II

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, CA. 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

• Collaborative leadership 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 high‑level design decisions (facility, equipment, documentation, manufacturing strategy) and hands-on GMP execution during startup and ongoing operations. This role is ideal for technical leaders 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 across multiple areas, you will shape the design of Gilead’s new Foster City Biologics Drug Substance manufacturing plant and then start up and run 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.

• Develop, 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.

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

Operational Excellence, Digital Innovation, and Cross-Functional Support

• 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, recommendations, and decisions.

• Serve as a consultant and advisor to senior management and act as an external spokesperson for the organization on significant technical and business matters

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

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

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

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

• Interact with health authorities as a Subject Matter Expert and area representative during site inspections and through written regulatory submissions

Technical and Team Leadership

• Provide technical leadership, coaching, and mentorship to less experienced team members

• Demonstrate the Gilead Leadership Commitments as a visible technical leader:

• I AM BOLD in aspiration and AGILE in execution.

• I CARE and make time for people.

• I LISTEN, speak openly and explain the "why."

• I TRUST others and myself to make sound decisions.

• I OWN the impact of my words and actions.

• Model inclusive, transparent decision-making, combining diversity in thought and perspective with consistency and clarity in accountability

• This role may include management responsibilities in addition to technical leadership and matrix team management
