Senior Cloud Security Engineer

Company: Iceberg
Apply for the Senior Cloud Security Engineer
Location: London
Job Description:

Some security roles focus on policy. This one is about securing the platform from the ground up.

A highly sophisticated, engineering-led organization is seeking a Senior Cloud Platform Security Engineer to design, implement, and scale secure-by-default infrastructure across Kubernetes, cloud, and software delivery environments.

This is not a traditional governance or operations security role. It requires a deeply hands‑on engineer who can embed security directly into clusters, pipelines, cloud architecture, and platform design—building guardrails that enable engineering rather than block it.

You’ll play a critical role in securing modern infrastructure across Kubernetes, CI/CD, Azure cloud, Infrastructure-as-Code, and software supply chain, with significant ownership over how secure engineering is delivered at scale.

The Role

  • Design and implement Kubernetes security controls across enterprise platform environments
  • Secure CI/CD pipelines through signing, provenance, credential hardening, and policy enforcement
  • Build secure cloud infrastructure patterns across Azure environments
  • Harden Infrastructure-as-Code modules across Terraform and Bicep
  • Strengthen software supply chain security, container security, and image governance
  • Develop automation, tooling, and scripting to operationalize security at scale
  • Partner directly with platform and DevOps teams on secure architecture
  • Help shape long-term cloud and platform security strategy

What You’ll Be Doing Early

  • First 6 months focused heavily on Kubernetes security
  • Securing clusters, deployment pipelines, and runtime environments
  • Following projects expand into broader cloud security ownership
  • Longer term progression into secure software and cloud platform engineering
  • Strong hands‑on Kubernetes experience in production environments
  • Deep cloud or platform security engineering capability
  • Experience with Terraform, Bicep, or similar Infrastructure-as-Code
  • Strong scripting ability (Python, Go, Bash, or similar)
  • Experience securing CI/CD pipelines and modern software delivery
  • Strong understanding of IAM, RBAC, secrets management, and secure architecture
  • Excellent academic background (high standards expected)
  • Ability to operate in a highly technical, performance‑driven environment

Highly Valuable

  • Azure security experience
  • Financial services, hedge fund, or high‑performance enterprise background
  • Supply chain security
  • Security tooling such as OPA/Gatekeeper, Kyverno, Falco, or equivalent
  • Certifications such as CKS, AZ-500, or OSCP

Why This Role

This is a rare opportunity to join an elite engineering environment where security is treated as a core engineering discipline—not a support function.

For the right person, this role offers the chance to:

  • Build secure cloud‑native infrastructure
  • Own meaningful platform security initiatives
  • Progress from Kubernetes security into broader cloud and software security leadership
  • Work in a technically demanding, high‑caliber organization where implementation quality matters

If you’re a deeply technical security engineer who wants to build, harden, and shape secure infrastructure at scale, this is the kind of opportunity that rarely reaches the market.
