Job Description
 

As part of Gilead’s enterprise AI strategy to accelerate insights and decision‑making, we are seeking an Sr Manager, Data/AI Solution Architect to lead the design of Data and AI solutions across the HR & LCCR Functions. In this role, you will partner closely with business stakeholders, and Data/AI Product Owners, Technical Delivery Leads and Platform Leads to determine the right solution architecture for predictive analytics and AI‑driven insights. You will drive technical excellence through architectural design, modeling approach, and platform selection—ensuring scalable solutions, aligned to Gilead standards, that translate complex digital needs into actionable insights.

This position will report to the Director, Data/AI and is based in Foster City, CA (hybrid‑eligible).

Key Responsibilities:

Solution design & delivery: Partner with function business process leads across HR, Compliance, and Legal to assess needs and translate them into practical AI solution designs and serve as the technical lead across solutions.

Model development & tuning: Build, fine-tune, and evaluate AI/LLM models grounded in policy, procedural, and regulatory requirements, and adaptable to Gilead-specific content, internal materials, and approved templates.

Knowledge base engineering: Design and maintain retrieval-augmented (RAG) knowledge bases incorporating authoritative external guidance, corporate policy libraries, compliance frameworks and codes of conduct, and Gilead-specific documentation.

Review & workflow automation: Develop reusable capabilities for document review, summarization, consistency and policy-alignment checking, citation accuracy, and risk flagging — with traceable citations back to source content.

Data pipelines: Engineer secure, scalable ingestion and processing pipelines for diverse content types across enterprise support functions, including policy and procedure documents, employee-facing communications, training and enablement materials, internal narratives, external publications, and structured business records.

Delivery through extended teams: Direct execution through engineers, vendor partners, and shared platform resources — setting technical direction, reviewing designs, ensuring quality, and driving solutions to production at a scale beyond individual delivery.

Evaluation & quality: Establish evaluation frameworks, accuracy benchmarks, guardrails, and human-in-the-loop validation to ensure trustworthy, defensible, and auditable outputs.

Stakeholder collaboration: Act as the bridge between business stakeholders and AI delivery — converting functional review and knowledge-work needs into trusted, auditable solutions that reduce cycle time and organizational risk. Drive adoption, enablement, and change management.

Governance: Ensure solutions meet data privacy, confidentiality, security, and responsible-AI standards, with role-based access appropriate to sensitive enterprise content.

MLOps: Implement model deployment, monitoring, versioning, and continuous improvement practices, and establish reusable architecture standards and delivery patterns across the portfolio.
