- Own infrastructure-as-code for all cloud environments using Terraform maintaining modular library, enforcing naming conventions, and managing state backends with appropriate locking and access controls.

- Architect and implement cloud-native security controls: IAM least-privilege roles, SCPs/Azure Policy, network security groups, WAF rulesets, and DLP posture management using CSPM tooling.

- Design multi-region data residency architectures for customers in regulated sectors (BFSI, government, healthcare) ensuring compliance with RBI, IRDAI, and DPDP Act data localisation requirements.

- Manage cloud cost optimisation initiatives reserved instance / savings plan strategy, rightsizing recommendations, and Kubernetes compute cost allocation with Kubecost.

- Support BYOC deployment engineering: work with enterprise customers cloud teams to deploy Rubiscape into customer-owned AWS / Azure / GCP / OCI accounts with agreed network isolation and egress controls.
