AWS DevSecOps Engineer

We are looking to hire a DevOps Engineer to deliver hands-on remediation of cloud security findings across our AWS environment. Working under the direction of our AWS Security Lead and alongside Developers and Data Engineers, you will turn prioritised findings into engineering work — fixing misconfigurations, hardening infrastructure, and building guardrails into our Infrastructure-as-Code. Your primary strength is DevOps and cloud engineering on AWS (infrastructure, automation, CI/CD); a solid working understanding of cloud security and vulnerability remediation is essential.

Key Responsibilities

• Deliver end-to-end remediation of cloud and infrastructure findings: implement fixes, test safely, and track through to closure.
• Translate prioritised security findings into practical engineering tasks and apply the fixes in code and infrastructure.
• Harden AWS infrastructure across networking, compute, storage, IAM configuration, and encryption — delivered through Infrastructure-as-Code.
• Build and maintain reusable IaC modules and account baselines so resources are provisioned secure by default.
• Embed automated security and policy checks into CI/CD pipelines and pull-request workflows to prevent regressions.
• Automate repetitive remediation and control validation through scripting to clear work quickly and safely across accounts.
• Configure, tune, and operate AWS security and posture-management services as directed by the Security Lead.
• Partner with Developers and Data Engineers to ship secure fixes, and produce clear runbooks and progress reporting for technical and non-technical stakeholders.

Required Skills & Experience

• Strong, hands-on AWS experience across compute, networking, storage, IAM, and serverless.
• Proven Infrastructure-as-Code with Terraform and/or CloudFormation (modules, state, multi-account patterns); able to review and fix weaknesses in IaC.
• CI/CD pipeline experience (pipelines, branching, PR workflows, pipeline guardrails) with common tooling such as Jenkins, Bitbucket, GitHub Actions, GitLab CI or similar.
• Scripting and automation skills in Python, Bash, or similar to streamline remediation and control validation.
• Experience operating in multi-account AWS environments (Organizations, landing zone / Control Tower concepts) with sound change-management discipline (testing, staged rollout, rollback).
• Solid working understanding of cloud security fundamentals: network exposure and segmentation, public-access controls, least privilege, encryption in transit and at rest, and instance/workload hardening.
• Practical experience remediating a range of findings: cloud misconfigurations, OS/package CVEs, container images, and third-party dependencies.
• Comfortable acting on findings from scanning / CSPM tools and validating that fixes are effective.
• Able to work to a prioritised backlog and SLAs, and to coordinate exceptions and sign-off with the Security Lead.

AWS Security Controls (Working Knowledge)

• Familiarity implementing common AWS security controls in practice, including:
• IAM roles, policies, permission boundaries, and least-privilege configuration
• VPC segmentation, security group/NACL design, and private endpoints
• Encryption using KMS, TLS, and secrets management
• Logging and monitoring with CloudTrail, CloudWatch, and Config
• Native posture-management and threat-detection services
• Awareness of common control frameworks (CIS AWS Foundations, AWS Well-Architected Security Pillar).

Nice to Have

• Certifications such as AWS Solutions Architect, AWS SysOps, AWS DevOps Engineer, or AWS Security Specialty.
• Experience supporting data platforms on AWS (Glue, EMR, Redshift, Athena, RDS, OpenSearch, Kafka/MSK).
• Container and serverless platform experience (ECR, ECS/EKS, Lambda, image scanning, runtime hardening).
• Experience with policy-as-code and automated control enforcement (OPA/Conftest, tfsec, Checkov).

Personal Attributes

• Highly collaborative and pragmatic; you enjoy working directly with engineers and the Security Lead to ship secure fixes quickly.
• Strong engineering judgement and the ability to balance urgency with operational impact and stability.
• Clear communicator who can write concise runbooks and report progress to stakeholders.
• Ownership mindset: you drive remediation through to completion, not just identification.
