M365 Platform Manager

The Microsoft 365 Platform Manager owns the definition, evolution, and architectural integrity of UL Solutions’ Microsoft 365 platform while leading and developing the M365 team. This role is accountable for ensuring Microsoft 365 operates as a coherent, secure, and value driven ecosystem—spanning collaboration, content, automation, and AI—rather than a collection of disconnected tools.

This is a player/coach role. The successful candidate will set architectural direction, establish standards and guardrails, coach a team of M365 professionals, and provide governance and escalated operational decision making. Day to day administration and operational execution remain with the existing technical teams and service owners.

The role partners closely with Digital Workplace leadership, Cyber Security, Automation (Power Platform), Digital Adoption, and other domain owners to ensure intentional, scalable, and responsible use of Microsoft 365 capabilities, including Copilot.

• Establish a team operating rhythm (planning, architectural review, prioritization, skills development/certifications) that sustains delivery while protecting architectural integrity.

• Provide governance‑level oversight for Microsoft 365, focused on decision‑making rather than execution.

• Serve as escalation point for complex, high‑impact operational issues requiring architectural or cross‑domain decisions (e.g., risk tradeoffs, major design direction, non‑standard requests).

• Shape platform demand intake and prioritization through an architectural lens; ensure decisions align with target‑state architecture and established standards.

• Provide architectural leadership for Microsoft 365 Copilot and AI‑enabled workplace experiences.

• Ensure Copilot adoption aligns with information architecture and collaboration patterns, security/privacy/compliance requirements, and adoption readiness/user experience considerations.

• Partner with stakeholders to integrate AI intentionally into the flow of work.

• Partner closely with Digital Adoption / Change & Enablement teams to align platform design with adoption strategy and readiness.

• Collaborate with Automation and Power Platform domain owners to define architectural boundaries, governance models, and integration patterns (delivery owned elsewhere).

• Work in close alignment with Cyber Security and Information Protection teams to ensure Microsoft 365 architecture supports enterprise security, identity, data protection, and compliance standards.
