We are seeking a hands-on Security Engineer to embed within a large-scale cloud migration programme, moving workloads into AWS. You will be responsible for designing, automating, and enforcing security controls throughout the migration lifecycle — ensuring that every workload lands in AWS with a secure, compliant, and auditable posture. This is a technical, build-focused role combining cloud security architecture, infrastructure-as-code, and Python automation.

Key Responsibilities

• Define and implement the security controls, guardrails, and landing zone baseline for workloads migrating to AWS.

• Design and operate AWS-native security tooling across accounts and Organizations (see Technical Skills below).

• Build security automation in Python — remediation Lambdas, compliance-check scripts, event-driven response, and integrations with ticketing/SIEM systems.

• Author, review, and maintain infrastructure-as-code (Terraform and/or CloudFormation) for security services, guardrails, IAM, networking, and encryption.

• Integrate security into GitLab CI/CD pipelines — SAST, IaC scanning, secrets detection, dependency/container scanning, and policy-as-code gates.

• Assess the security posture of workloads before, during, and after migration; identify and remediate misconfigurations and vulnerabilities.

• Design secure network segmentation and connectivity between source environments and AWS (Direct Connect / VPN, Transit Gateway, security groups, NACLs).

• Implement IAM least-privilege models, identity federation, and secrets management for migrated workloads.

• Define encryption standards (at rest and in transit) using KMS, ACM, and TLS policy.

• Support compliance and audit requirements (e.g. CIS Benchmarks, NIST, ISO 27001, SOC 2, PCI-DSS as applicable) and produce evidence.

• Partner with migration, platform, and application teams to unblock security issues without slowing delivery.

• Contribute to incident detection and response runbooks for the AWS environment.
