Software Engineer III - DevSecOps - Kubernetes Security (International Consumer Bank)

Reference: lj7gzr6gavrz9xwgqxeo

We are seeking a Software Engineer III specialising in DevSecOps and Kubernetes security to help design, build and operate secure, resilient cloud-native platforms. Working within a collaborative engineering team, you will play a key role in embedding security throughout the software development lifecycle and enabling teams to deliver reliable services at pace.

You will develop and maintain secure Kubernetes platforms across cloud and hybrid environments, strengthening cluster configuration, workload isolation, identity and access management, secrets handling, network policies and container security. You will create reusable infrastructure and automation using infrastructure-as-code and support consistent, repeatable deployment practices across engineering teams.

The role will involve integrating security controls into CI/CD pipelines, including image scanning, vulnerability management, policy enforcement, runtime monitoring and automated compliance checks. You will investigate security findings, assess risks, support remediation and contribute to incident response activities. You will also help define platform security standards, improve observability and produce clear technical documentation and guidance for developers and operational teams.

As a senior contributor, you will participate in architecture discussions, technical reviews and continuous improvement initiatives. You will coach less experienced engineers, promote secure engineering principles and work closely with platform, application, infrastructure, risk and assurance stakeholders to solve complex problems effectively.

We are looking for experience in software engineering, DevSecOps or platform security, with strong practical knowledge of Kubernetes and container technologies. You should be confident with at least one major cloud platform, Linux administration, networking and scripting or programming languages such as Python, Go or Bash. Experience with tools including Terraform, Helm, Git-based workflows and common CI/CD platforms is highly desirable.

You will bring a security-first mindset, strong troubleshooting skills and the ability to communicate technical concepts clearly to varied audiences. Experience working in regulated environments, implementing security frameworks or supporting highly available production services would be advantageous. Relevant cloud, Kubernetes or security certifications are welcome but not essential.
