Software Engineer III - DevSecOps - Kubernetes Security

Reference: 24fxwj1uejc0ctqrtgpn

We are seeking a Software Engineer III specialising in DevSecOps and Kubernetes Security to help design, develop and improve secure, resilient cloud-native platforms. You will work across software engineering, infrastructure and security teams to embed security throughout the development lifecycle, from design and coding through to deployment and ongoing operation. The role will involve building and maintaining Kubernetes security capabilities, strengthening platform controls and helping engineering teams adopt secure-by-default practices without compromising delivery.

Your responsibilities will include developing automation for secure container and Kubernetes environments, implementing policy-as-code, and integrating security checks into CI/CD pipelines. You will assess vulnerabilities across container images, clusters, dependencies and infrastructure, support remediation, and contribute to threat modelling, security reviews and incident response. You will also help define engineering standards, improve observability and auditability, maintain technical documentation, and provide guidance on identity and access management, secrets handling, network segmentation and workload isolation. As a senior contributor, you will influence technical direction, review designs and code, mentor colleagues, and collaborate with stakeholders to resolve complex security and reliability challenges.

You will bring substantial experience in software engineering, DevSecOps or platform security, together with strong hands-on knowledge of Kubernetes and container technologies. Proficiency in one or more programming or scripting languages, such as Go, Python or Bash, is expected, alongside experience with cloud platforms, Linux, infrastructure as code and automated delivery pipelines. You should understand Kubernetes security controls, admission policies, RBAC, network policies, supply-chain security and vulnerability management. Experience with tools such as Terraform, Helm, image scanning platforms and Kubernetes policy engines would be advantageous. We are looking for a pragmatic, collaborative engineer who can communicate clearly, work independently, and balance robust security with reliable, scalable delivery.
