You will have the opportunity to actively leverage AI tools to accelerate engineering tasks, automate repetitive work, and improve documentation.

- Security and compliance: CIS benchmarks, SOC2, HashiCorp Vault, Wiz, GuardDuty, encryption and key management
- Platform operations: Prometheus/Grafana observability, disaster recovery, cloud cost optimisation, third‑line on‑call
