•  Clearly communicate production risks, trade-offs, and technical constraints
•  Provide constructive feedback to improve operability
•  Share knowledge and context to support teams and colleagues

Impact & Delivery Expectations

•  Deliver measurable improvements in service reliability and operational resilience
•  Reduce repeat incidents through automation and systemic fixes
•  Improve MTTR and detection capabilities across services
•  Ensure services have defined SLOs, telemetry, and operational standards
•  Balance short-term remediation with long-term reliability engineering

Qualifications, Experience and Skills

•  Experience in cloud environments
•  Hands-on experience with Kubernetes and containerised systems
