* Establish and lead framework for incident management and response. Lead the strategy to meet SLAs across service uptimes and limit incidents that result in customer impact

* Experience with CI/CD and automation
* Pragmatic mindset — you value reliability and simplicity over complexity
Why This Role
* Real ownership across platform and IT — not siloed
* Opportunity to shape how platforms and operations scale together
