Senior Cloud / AWS Infrastructure Engineer

Seeking.com (Reflex Media) is hiring a Senior Cloud / AWS Infrastructure Engineer to build, operate, and secure the AWS environment that runs its products. The role focuses on Terraform-based cloud architecture, cross-region disaster recovery, security controls and identity, and infrastructure reliability and automation.

Responsibilities:

• Extend the Terraform module library and the AFT customization layers (VPC and IPAM allocation, private hosted zones, SSM access, backup vaults, account baselines) so new accounts land secure and consistent by default
• Design VPC architecture, cross-account networking, and shared services in a hub-and-spoke configuration model
• Migrate legacy brand infrastructure into the current account structure, state backend model, and module standards
• Design and build cross-region recovery for a flagship platform: Aurora replication topology, cross-region backup copy, S3 and EFS replication, container image distribution, DNS failover, and region-parity IaC
• Establish RPO and RTO targets with the business, map dependencies into recovery tiers, and define restoration order
• Standardize backup policy and retention across the estate, including organization-level backup policy and centralized vaults
• Run scheduled DR tests and game days, and write runbooks that make recovery repeatable by anyone on call
• Design least-privilege IAM policy and IAM Identity Center permission sets. Reduce standing access and direct assignments
• Replace long-lived IAM access keys with federated SSO, OIDC, and assumed-role access, including in CI/CD
• Author and maintain SCPs and organization controls, plus automated remediation where prevention is not possible
• Extend detective controls: AWS Config rules and conformance packs, Security Hub standards coverage, GuardDuty feature coverage, and consistent finding handling across regions
• Own secrets management on Secrets Manager and SSM Parameter Store, including rotation
• Support incident response and CloudTrail forensics, and convert findings into durable engineering fixes
• Operate core infrastructure: monitoring, alerting, AWS Backup, and patch and lifecycle management
• Improve our Prometheus, Grafana, and Alertmanager stack and its CloudWatch alarm coverage so real issues page quickly
• Debug production issues across compute, storage, networking, and databases
• Automate operational work in Python and Bash, and improve CI/CD for infrastructure
• Keep Control Tower and the landing zone current, and contribute to cost visibility and optimization

Requirements:

• Five or more years building and operating production AWS infrastructure
• Strong Terraform in a team setting: module design and versioning, remote state, drift, and PR-based workflows
• Multi-account AWS Organizations or Control Tower experience, including SCPs and cross-account IAM
• Deep IAM: policy and trust-policy design, permission boundaries, and least privilege in practice
• Production container experience on ECS or Kubernetes, and managed relational databases
• Python or Bash for automation and tooling
• Experience migrating or consolidating legacy infrastructure without downtime, and the judgment to sequence that work safely
• Clear writing, and the judgment to weigh risk, cost, and delivery speed against each other
• Daily use of Claude, Claude Code, and Cowork in your engineering workflow
• AFT, Landing Zone Accelerator, or similar account-vending automation
• IAM Identity Center or SAML / OIDC federation with an external IdP
• Designing and testing cross-region DR against defined RPO and RTO targets
• Aurora operations at scale: replication topology, failover, and backup and restore
• Security Hub, GuardDuty, AWS Config, or SIEM-style CloudTrail analysis. EDR tooling such as CrowdStrike
• AWS Backup at organization scale, including cross-region and cross-account copy
• Cloudflare or a comparable CDN and WAF at the edge
• Data or AI workloads on AWS (Redshift, MWAA, Bedrock)
• Working with distributed teams across time zones
• AWS certifications (Solutions Architect, SysOps, Security Specialty)
• Bachelor's degree in Computer Science, Engineering, or a related field, or an equivalent operational track record
