Introduction to Role
Are you ready to engineer and run security platforms at general scale — platforms that keep critical science safe and moving? Join a high-impact team protecting the infrastructure that enables researchers, engineers, and clinicians to deliver life-changing medicines.
This is a hands-on, high-autonomy role centred on Microsoft Sentinel and Microsoft Defender, operating across hybrid and cloud-native environments. You'll own the health, performance, and evolution of our SIEM and EDR platforms — tuning configurations, validating telemetry, elevating alert quality, and resolving operational issues so that signals are trustworthy and action is fast. You'll also support NAS Protect and related protection capabilities across endpoint, network, identity, storage, and cloud.
We're looking for someone who brings critical thinking, automation instincts, and a genuine AI-first mindset — someone who sees repetitive toil and immediately thinks "how do I make a machine do this better than I can?" If you've lived through a SIEM migration (particularly Splunk to Sentinel),



you already know the kind of complexity and reward this role delivers.
This role is based in Guadalajara, Mexico with a hybrid model requiring a minimum of three days on-site per week.
