Inside IR35

We have lots of roles available at different seniority levels. Accountabilities will vary depending on role, but will follow these principles:
* Own and deliver engineering platform capabilities that enable teams to build, test, secure, and deploy services in a highly-automated, CI/CD-driven environment.
* Design, implement, and evolve CI/CD pipelines, ensuring consistent, reliable, and repeatable delivery processes across multiple teams and services.
* Embed Infrastructure-as-Code (IaC) practices, driving standardisation, scalability, and elimination of manual provisioning and configuration drift.
* Integrate security controls into engineering workflows, ensuring services are secure by design and comply with the highest standards, from initial build through to production.
* Support and enable engineering teams, providing guidance, tooling, and best practices to improve delivery velocity, quality, and resilience.
* Continuously optimise automation, identifying opportunities to remove repetitive manual tasks, reduce cycle times and improve developer experience.
* Collaborate across development, security, and operations spheres, breaking down silos and promoting end-to-end ownership of services.
* Maintain and improve engineering tooling and platforms, including source-code control systems, build systems, artifact repositories and deployment frameworks.
* Drive adoption of modern engineering practices, including continuous integration, continuous delivery, automated testing, and observability.
* Monitor and improve platform performance and reliability, using metrics such as deployment frequency, lead-time, failure rates, and recovery times.
* Contribute to technical standards and governance, ensuring consistency, security, and best-practice across engineering teams.
* Support incident response and problem resolution, ensuring rapid recovery and continuous improvement through feedback loops and retrospective sessions.
* Document and share knowledge, building reusable patterns, templates and guidance in order to scale up engineering capability.
