Contract Type:

Permanent
Closing Date:

30 August 2026

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.

The Tech Stack

You'll work with a modern, cloud-native platform, including:

Cloud & Networking: AWS (multi-account, IAM, VPC, managed services), hybrid/on-prem connectivity
Containers & Orchestration: Docker, Kubernetes (EKS, ECS)
Infrastructure as Code: OpenTofu, Terragrunt, CloudFormation
CI/CD: GitLab CI, reusable components, self-hosted runners
Security & Identity: Microsoft Entra, AWS IAM, OIDC, secrets management, policy-as-code
Observability: Centralised logging, metrics, tracing (e.g. Datadog, OpenTelemetry)
Platform Automation: Declarative configuration and infrastructure management
Internal Tooling: Developer-facing tools and services built with Python, Go, and modern frontend frameworks
Version Control: Git, merge requests, and code review workflows

We value strong fundamentals over specific tools—if you understand the principles, you'll thrive here.

What You'll Do

Design, build, and operate secure cloud and platform capabilities
Embed security controls across the software delivery lifecycle by default
Build and maintain fast, reliable, secure CI/CD pipelines and reusable components
Automate security, compliance, and operational checks
Partner with engineering teams to remove friction and improve workflows
Contribute to platform architecture, standards, and technical direction
Promote ownership, continuous improvement, and pragmatic DevSecOps practice

Key requirements:

Hands-on experience as a DevSecOps Engineer, Platform Engineer, Cloud Security Engineer, or similar role
Strong understanding of DevSecOps principles, including CI/CD, infrastructure as code, and security automation
Solid experience working in AWS environments
Practical knowledge of containerised workloads and Kubernetes
Clear communication skills and the ability to work effectively across teams
A focus on raising engineering standards through practical, scalable solutions

Why Holland & Barrett?

You will be joining at a point where the platform is still being actively shaped, with real scope to influence how security and delivery work across the organisation.

This role offers autonomy, technical ownership, and the opportunity to build foundational capabilities that directly impact hundreds of engineers. We offer a competitive salary, comprehensive benefits, and flexible working arrangements.

If you enjoy building secure platforms that developers actually love, we'd love to hear from you.
