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 organization.

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.
