SRE sits at the heart of our operational trifecta alongside Platform Engineering and DevSecOps. In this role, you’ll act as the go-to authority in your area of specialism, working across teams to embed best practices, solve complex reliability challenges, and improve system resilience at scale.
Unlike a generalist SRE, this role focuses on a core domain of expertise—such as observability, performance engineering, data infrastructure reliability, security-focused SRE, or network reliability—while influencing reliability standards across the wider engineering organisation.

- Collaborate with DevSecOps to integrate security, compliance, and resilience practices
- Contribute to cross-team initiatives that improve reliability across the stack
- Play a key role in incident response, particularly within your specialism
- Contribute to on-call rotations and continuous improvement of operational processes
- Develop runbooks, documentation, and training materials to support teams
- Proven experience in Site Reliability Engineering, DevOps, or infrastructure engineering
- Deep expertise in at least one of the following areas:
- Observability & monitoring (metrics, logging, distributed tracing)
- Performance engineering & capacity planning
- Data infrastructure reliability (databases, streaming, pipelines)
- Security-focused SRE (hardening, compliance automation, secrets management)
- Network reliability & traffic management
- Strong programming skills (e.g. Go, Python, or similar)
- Experience with cloud platforms (AWS, GCP, Azure) and Kubernetes
- Strong communication skills, with the ability to explain complex technical concepts clearly
- Self-driven with the ability to identify and prioritise high-impact work independently
- Experience building internal developer platforms or tooling
- Contributions to open-source, technical blogs, or public speaking
- Experience working in regulated environments
- Familiarity with SLO frameworks and error budget management
- Relevant certifications in your specialist domain
- Improved reliability and performance within your domain of specialism
- Adoption of best practices across SRE, Platform Engineering, and DevSecOps
- Reduction in incidents and faster resolution times
- Scalable, well-integrated solutions within the internal platform
- Strong collaboration across teams and measurable improvements in operational maturity
- Shape reliability strategy in a modern, cloud-native engineering environment
- Work on complex, high-impact systems at scale
- Collaborate with expert teams across Platform Engineering and DevSecOps
- Take ownership of a domain and drive meaningful, organisation-wide impact
