Senior DevSecOps Engineer

We're building a secure, cloud-native platform that underpins how software is delivered across the organisation. Following a major digital transformation, our platform enables teams to ship high-quality software quickly, safely, and consistently—by default. As we continue to scale, security, reliability, and developer experience are treated as first-class concerns, designed in from the start. This role sits at the heart of that mission, shaping how security is applied at scale and how engineering teams confidently move from idea to production. About The Role As a DevSecOps Engineer, you'll be a hands-on contributor to the design, build, and operation of our internal platform. This is a delivery-focused role, working closely with SRE, Cloud, and Application Security teams to embed security controls, guardrails, and best practices directly into tooling, pipelines, and infrastructure. You'll help define how security is applied at scale in a pragmatic, developer-friendly way, influencing engineering culture through code, automation, and clear technical standards—raising the baseline for security and operational excellence across the organisation.
