Microsoft 365 Cloud Tech Lead

Optiver's Global Enterprise Clients team owns the global Microsoft 365 platform — collaboration, messaging, identity, and mobile access — that our entire worldwide workforce runs on every day. It's treated as critical production infrastructure, not a back-office system. You'll join an established, distributed group of Microsoft 365 Cloud Technical Leads spread across our global offices, operating a single global platform, in a hands-on role with real architectural influence: engineers here design solutions, validate them with peers, and implement them directly. Observability, continuous capability uplift, CI-driven change, and self-healing automation are central to how we keep this platform reliable at scale.

What you'll do

• Set direction and design standards for our global Microsoft 365 platform across collaboration, messaging, identity, and device access
• Lead arcitectural decisions end-to-end — design, peer validation, implementation — driving change from inception through global rollout and adoption, with full ownership of global deliverables
• Drive
