The EH Way

• Mission First – everything we do (from what we work on, to how we allocate capital and where we focus) is driven by our Mission
• Remote First – we champion a remote environment with a preference for asynchronous communication and a high degree of autonomy
• AI First – we are committed to using AI to accelerate our mission; AI is not just a tool, it’s a fundamental part of how we operate, innovate, and scale
• Apolitical – we do not take a position on political or social topics, unless it relates to our Mission
• We Live by Our Values – we role model our values 100% of the time
• We Expect High Performance – we set a high standard and we’re not satisfied with being average

This role

The Cloud Security Engineer is responsible for securing our AWS environment, with a strong focus on automation, AI-assisted workflows, and scalable security controls. This role is not just about fixing issues, but about building intelligent systems that continuously detect, prioritise, and remediate cloud risks with minimal manual effort.

As a Cloud Security Engineer, you will be responsible for:

• Cloud Security Engineering

  • Partner with SRE and Engineering to embed security into infrastructure and deployments
• AI‑Driven Detection & Response
  • Leverage AI tools to triage, prioritise, and investigate cloud security findings
  • Build workflows that correlate signals from cloud logs, EDR, and third‑party tools into actionable insights
  • Continuously improve detection coverage using AI‑assisted analysis
• DevSecOps & Automation
  • Build automated security checks into CI/CD (IaC scanning, dependency risk, secrets detection)
  • Use AI to accelerate vulnerability triage and remediation workflows
  • Reduce manual security effort through scripting, automation, and intelligent tooling
• Security Data & Intelligence
  • Integrate and analyse data from sources such as SBOMs, vulnerability feeds, and threat intelligence
  • Use AI to identify patterns, emerging risks, and prioritisation signals across large datasets
  • Contribute to internal “security data platform” initiatives

Who You Are

Required

• Strong experience securing AWS environments
• Solid understanding of IAM, networking, logging, and cloud‑native architectures
• Experience with infrastructure‑as‑code (e.g. Terraform) and CI/CD pipelines
• Ability to script and automate (Python, Bash, or similar)
• Familiarity with SBOM, supply chain security, and dependency risk management
• Experience using or integrating AI tools in engineering or security workflows

Preferred

• Experience with tools like AWS Security Hub, GuardDuty, Wiz, or Datadog
