• 7+ years in backend engineering, including 5+ years of deep, production-level experience with Go & gRPC.
• Strong expertise in IAM: OAuth 2.0, OIDC, SSO, MFA, RBAC, and cryptography.
• Hands-on experience with AWS, Kubernetes, and IaC (Terraform / Terragrunt / OpenTofu).
• Solid understanding of web security, federated identity, and OWASP Top 10.
