Are you an accomplished Site Reliability Engineer with a passion for leadership and AWS innovation?

We’re partnering with a high-growth technology company that is seeking a Site Reliability Engineering (SRE) Team Lead / Technical Lead to join their world-class engineering function. This is not your average technical leadership role - you’ll be driving strategic reliability initiatives, shaping cloud infrastructure best practices, and leading a team of talented SREs committed to automation, scalability, and operational excellence.

What You’ll Be Doing

  • Lead, coach, and grow a high-performing DevOps/SRE team.
  • Define and execute the SRE strategy to support scalability, performance, and resilience across critical systems.
  • Own and evolve the AWS infrastructure - think EC2, RDS, ECS, Fargate, IAM, VPC and beyond.
  • Champion Infrastructure as Code and drive automation using Ansible (with exposure to Terraform or CloudFormation a plus).
  • Collaborate with cross-functional teams to deliver seamless, high-availability services.
  • Lead incident management processes, improve observability, and enforce SLAs/SLOs using tools like CloudWatch, Prometheus, and Datadog.
  • Act as a technical mentor and thought leader within both your team and the broader engineering organisation.

What We’re Looking For:

  • Proven leadership experience within SRE, DevOps, or Infrastructure teams.
  • Hands-on mastery of AWS services and cloud-native design patterns (microservices, containers, serverless).
  • Proficient in Ansible (Terraform knowledge is a strong advantage).
  • Strategic mindset with a strong grasp of SRE principles.
  • Track record of mentoring engineers, promoting best practices, and enabling high performance.
  • Solid understanding of monitoring, logging, and incident response.
