Responsibilities
- Own reliability outcomes for critical user journeys and cloud components by defining SLIs/SLOs, setting error budgets, and using data to prioritise resilience work.
- Design observability standards (metrics, logs, traces, dashboards, alerting) using tools such as Datadog and AWS CloudWatch so teams can detect issues early and diagnose them quickly.
- Lead major incident response as incident commander when needed, drive blameless post-incident reviews, and ensure corrective actions are implemented and measured.

Qualifications

- Strong AWS knowledge and hands-on experience operating cloud services (for example: EKS, Lambda, SQS, API Gateway, DocumentDB, RDS/MySQL, and CloudWatch/CloudWatch Insights).
- Experience with infrastructure-as-code and automation (for example, Terraform) and with CI/CD pipelines (for example, GitLab CI/CD).
- Experience with Kubernetes, including production operations on managed platforms such as Amazon EKS.
- Ability to script to automate and solve (for example, Python and/or JavaScript), with an engineering approach to testing, review, and maintainability.
- Experience building actionable monitoring and alerting that balances sensitivity and noise (for example, Datadog and CloudWatch).
- Confidence presenting, staying calm during incidents, and influencing teams through data, clear writing, and pragmatic recommendations.
