As a Principal Site Reliability Engineer, you will be a senior technical leader focused on scaling and hardening our AWS- and Kubernetes-based infrastructure. You will work across product, platform, and operations teams to ensure our systems are reliable, observable, and resilient — even at scale.

This role combines hands-on technical capability with strategic vision, helping us build a world-class reliability culture and a robust engineering foundation for growth. We're looking for someone who has technical expertise, is a great communicator and enjoys collaborating across multiple teams.

• Guide the team in building automated, self-healing systems
• Own and evolve our incident response processes, including on-call practices and post-mortem culture
• Mentor engineers across the organization on best practices in reliability, operational readiness, and scalable infrastructure
• Drive Infrastructure as Code (IaC) using Terraform, Kubernetes, CloudFormation, and GitOps practices
• Collaborate closely with security, DevOps, and software teams to ensure compliance, scalability, and operational excellence
• Evaluate and introduce tools, patterns, and practices that improve the performance and reliability of our SaaS platform

Desired Skills & Experience:

• Demonstrable experience leading SRE transformations
• Deep hands-on expertise with Kubernetes (EKS preferred) in production environments
• Strong experience with AWS core services (EC2, EKS, RDS, S3, ALB/NLB, IAM, CloudWatch, etc.)
• Expertise in Infrastructure as Code using tools such as Terraform, with knowledge of GitOps workflows
• Strong background in observability: metrics, visualization, logging, and tracing
• Understanding of automation, SDLC, CI/CD pipelines, deployment automation, and blue/green or canary releases
• Proven experience with incident management, disaster recovery planning, root cause analysis, and post-incident reviews

• Hybrid working - 1+ days a week in the London office

• Wellbeing initiatives including Sanctus Coaching, Virtual fitness sessions, Wellbeing webinars, and an Annual Wellbeing day

• Subsidised Gym Membership
• Private Medical Insurance (including Dental and Vision) and Life Assurance
• 25 days holiday (increasing to 30 days at a rate of 1 extra day per year)
• Summer Fridays (half-day Fridays for July and August)
• Employer pension contribution of 5% of your gross salary, if you contribute a minimum of 3%
• Season ticket Loan
