Job Description

Lynx are working with a leading consultancy who partner with fast-moving engineering teams who build and run their businesses in the cloud. They need pragmatic, code-literate security specialists.

The Role

They're looking for a hands-on AWS Security Architect who lives and breathes AWS. You'll dissect designs, model attack paths, and show engineering teams what good really looks like. Depending on the engagement, you might run a threat model, assess CI/CD pipelines, learn a vendor DSL for a PoC, or build internal tooling. They don't expect you to know everything - just to be curious, practical, and willing to dive in.

What You'll Do

  • Threat Modelling & Architecture Reviews: Break down AWS services, map trust boundaries, build attack trees, and define security requirements before code ships.

  • Security Automation: Build IaC-driven checks, Lambda/Step Function tooling, CI/CD gates, and CSPM rules to enforce secure defaults at scale.

  • Hands-On Testing & Hardening: Perform cloud-native testing (IAM escalation, container escape attempts, infra abuse) and guide fixes directly via PRs.

  • DevSecOps Enablement: Pair with platform teams, review Terraform/CloudFormation/Kubernetes, and promote least privilege, logging, and runtime controls.

  • Knowledge Sharing: Contribute to documentation, demos, and continuous learning within the team.

What You Bring

Must-Haves

  • Deep AWS internals knowledge

  • Technical/IT degree (2:1 or above)

  • Proven threat-modelling experience (STRIDE, attack trees, etc.)

  • Strong coding skills (Python, Go, Rust, etc.)

  • IaC expertise - Terraform, CrossPlane, Pulumi, CloudFormation, AWS CDK

  • CI/CD security automation experience (GitHub Actions, GitLab CI, Jenkins, etc.)

Nice-to-Haves

  • AWS Security Specialty, SANS, OSCP (skills over certificates, though!)

  • Multi-cloud or hybrid security experience

  • Container security & supply-chain/SBOM tooling

  • Applied cryptography fundamentals (KMS, envelope encryption, etc.)

  • Incident response or red/blue/purple team exposure

  • OSS security contributions or AWS community involvement
