Sr. Director, Solution Architecture

ROLE SUMMARY This role holds global architectural accountability for the Medical Affairs digital and AI portfolio — a multi-million-dollar technology landscape spanning Field Medical enablement, omnichannel HCP engagement, and next-generation Agentic AI and LLM-based systems. Scope includes the Medical Affairs technology blueprint, integration standards, solution architecture and reuse patterns. This role has direct impact on total-cost-of-ownership and ROI outcomes tracked against the annual technology investment budget.

This is a dual-impact role: the Sr. Director is simultaneously the chief architectural authority across a highly matrixed global ecosystem — partnering with a peer Sr. Director of Engineering, four Product Owners who define product vision across the Medical Affairs portfolio, and Pfizer Digital's federated architecture community — and a hands-on, working architect who personally designs and documents solution architecture for the highest-priority enterprise platforms.

The role is structured as a technical pod lead: it carries direct people-management accountability for a dedicated UX Designer and Scrum Master, giving this leader end-to-end accountability for technical design, user experience, and delivery cadence for the portfolio's highest-priority builds. This structure keeps design, architecture, and delivery accountable to a single leader rather than coordinated across separate reporting lines.

The Sr. Director also serves as a primary, trusted digital advisor to senior Medical Affairs business executives — including the Head of US Medical Affairs, Therapeutic Area/Category Leads, Field Medical Leads, MEI Leads and Compliance and Legal Leads — requiring the executive presence to translate advanced technical paradigms into value-driven business strategy and win alignment across stakeholders who do not report into this role.

The Sr. Director, Solution Architecture, Medical AI Acceleration and Delivery is globally accountable for defining and driving end-to-end solution design, data integration, and AI strategy across the Medical Affairs digital portfolio. This role directly architects next-generation Agentic AI platforms, LLM fine-tuning pipelines, and AI integrations into existing enterprise data systems, with key strategic priorities including AI-based productivity solutions for global Field Medical teams (e.g., MSLs) and automated, compliant omnichannel HCP engagement journeys — all within an intensely regulated global environment.

ROLE RESPONSIBILITIES Global Architectural Governance & Solution Design Establish, govern, and enforce architectural blueprints, integration frameworks, and technology standards across all Medical Affairs digital systems globally. Act as the primary solution architect for high-priority enterprise-wide platforms, directly defining and documenting technology solution approaches and component design.

Partner with four Product Owners and a peer Sr. Director of Engineering to translate business capabilities into buildable, resilient target-state architectures. Ensure designs conform to pharmaceutical industry regulations (GxP, HIPAA, GDPR) and internal AI ethics and compliance frameworks. Drive data integration and architectural alignment across core enterprise platforms — Veeva CRM, PromoMats, Salesforce Life Sciences Cloud, and Salesforce Marketing Cloud.

Design and prototype autonomous and semi-autonomous AI agents, multi-agent workflows, and orchestration frameworks for Medical Affairs process automation. Architect multi-lingual, regionally compliant AI solutions accounting for divergent regulatory boundaries (e.g., EFPIA in Europe vs. FDA in the US). Establish environment strategy, ALM, and CI/CD pipelines for LLM-based solutions; oversee model tuning, RAG pipelines, and vector database management.

Implement AI telemetry to track model/agent performance, token usage, drift, and latency; design against prompt injection and enforce strict data access controls. Embe
