• Proactively identify and resolve performance, availability, and reliability issues
• Lead and contribute to incident response, troubleshooting, and root cause analysis
• Automate operational processes and eliminate repetitive manual tasks
• Work closely with software engineers to improve deployment processes, system reliability, and developer experience
• Help improve platform resilience, scalability, and disaster recovery capabilities
• Contribute to capacity planning and performance optimisation as the platform scales
• Establish and champion SRE best practices across the wider engineering function

What We're Looking For

• Proven commercial experience working as an SRE, DevOps Engineer, Platform Engineer, or similar
• Strong hands-on experience with AWS
• Strong experience working with Kubernetes
• Excellent experience with Terraform and Infrastructure as Code
• Strong experience building and managing GitHub Actions CI/CD pipelines

• Understanding of SLIs, SLOs, SLAs, and error budgets
• Experience with incident management and root cause analysis
• Good understanding of cloud networking, security, and infrastructure fundamentals
• Strong scripting/automation skills
• A strong understanding of reliability, scalability, performance, and availability
• Excellent communication skills and the ability to work closely with software engineering teams
• A proactive mindset and genuine passion for automation and continuous improvement

Don't Tick Every Box?

That's okay.

The company is open to speaking with engineers who may not have experience across every technology listed above.

If you have strong foundations in AWS, Kubernetes, Terraform, and cloud infrastructure, along with a genuine interest in reliability and observability, we'd still love to hear from you.

Why Join?
