About the role

Key responsibilities & impact

Designs, implements, and continuously improves AWS security architecture.
Partners with cloud engineering, platform engineering, DevOps, Risk & Compliance, and product teams to build secure-by-default patterns, guardrails, and automation that enable delivery velocity without compromising security.
Influences cloud security strategy while providing hands-on architectural and engineering support.
Designs secure reference architectures and reusable security patterns for AWS workloads, including identity, networking, encryption, logging, monitoring, and secrets management.
Implements and operates enterprise AWS guardrails using Organizations, Control Tower, SCPs, AWS Config (managed and custom rules), Security Hub, GuardDuty, Detective, Macie, WAF/Shield, and AWS Network Firewall.
Applies least-privilege IAM using roles, permission boundaries, session policies, IAM Identity Center, SAML/OIDC federation, and ABAC/RBAC where appropriate.
Uses IAM Access Analyzer and automated validation to identify and reduce risk.
Designs secure VPC architectures and establishes detection-as-code and telemetry standards using CloudTrail, VPC Flow Logs, Route 53, RDS, ALB/NLB, and S3 access logs; integrates detections with SIEM/SOAR platforms.
Supports incident response through detections, playbooks, and tabletop exercises.
Embeds security into CI/CD pipelines using policy-as-code, Terraform checks, container and image scanning, SBOMs, and pre-commit hooks.
Automates remediation and drift detection using Lambda, Step Functions, and Terraform.
Maps technical controls to security frameworks including CIS AWS Foundations, NIST, ISO 27001, SOC 2, PCI DSS, and HIPAA (as applicable).
Conducts threat modeling (e.g., STRIDE) and risk assessments and drives remediation to closure.
Reviews designs, provides architectural guidance, and produces clear documentation and runbooks.

Requirements

What you’ll need

7+ years of experience in cloud architecture and security, including leading cloud security programs or large-scale AWS transformations.
Hands-on expertise with AWS security services and controls, including Organizations, Control Tower, IAM/IAM Identity Center, KMS, Security Hub, GuardDuty, Detective, Macie, WAF/Shield, AWS Network Firewall, CloudTrail, Config, CloudWatch, VPC, Route 53, ECS, and Secrets Manager/Parameter Store.
Strong background in cloud identity and Zero Trust patterns, including workload identity, JIT access, break-glass design, and ABAC where appropriate.
Experience securing data at scale, including classification, DLP, tokenization, and access governance.
Deep understanding of networking and isolation patterns, including multi-region architectures, hybrid connectivity, egress controls, private endpoints, and service-to-service authentication.
Proficiency with infrastructure-as-code and automation tools (Terraform, Python/Bash, policy-as-code).
Experience with container and serverless security, including ECS hardening, image attestations, runtime controls, and least-privilege Lambda patterns.
Detection engineering experience, including logging strategies, detections-as-code, and SIEM/SOAR integration.
Familiarity with incident response and security investigations.
Strong governance, risk, and compliance knowledge with the ability to map controls to CIS, NIST, ISO, PCI, and HIPAA frameworks (as applicable).
Clear written and verbal communication skills, with the ability to produce concise design documentation and provide actionable guidance to engineering teams.
Ability to manage priorities effectively in a fast-changing environment.
Comfortable working in a remote or hybrid environment with limited in-person interaction.
