- Measure systems' health, scalability and performance metrics and identify areas of improvement.
- Ensure our incident management processes, automation, and remediation are world-class

Qualifications

- Deep AWS fundamentals: EKS/Kubernetes as a day-one runtime, Lambda/serverless, networking, multi-AZ
- Infrastructure-as-code (Terraform), CI/CD, and observability experience
- A real silent-failure story, caught or missed, that changed how you work
- Solid Go (or a strong track record of picking up new languages fast)
- Comfort with AI-assisted development
- Experience with identity resolution and consent or auth data modelling
- On-call ownership with considered views on alert fatigue
