About The Position

The Site Reliability Engineer will work closely with Infrastructure and Development teams to ensure the ADT platform runs smoothly and customers are protected. This role involves collaborating with cross-functional partners such as IT, Security, DevOps, and Engineering to enhance operational health and implement SRE best practices. The engineer will be responsible for the reliability, availability, scalability, and performance of large-scale distributed systems, driving operational excellence through problem-solving, performance improvements, and maintaining resilient production environments. The role utilizes tools like Terraform, Ansible, Kubernetes, and Dynatrace to support mission-critical applications within cloud environments (AWS, GCP) and Kubernetes-based infrastructure, with opportunities for guidance on complex design decisions. Key activities include identifying and resolving performance bottlenecks and reliability gaps, building and maintaining infrastructure as code, contributing to observability and monitoring systems, supporting software releases, and providing production support, including on-call participation and incident response.

Requirements

3+ years of experience in SRE, DevOps, platform engineering, software engineering, or related roles with production and on-call responsibility
Background in systems or operations with progression toward engineering work (automation, scripting, IaC, observability)
Focus on production operations and reliability for distributed applications
Experience with infrastructure as code (Terraform, Ansible), including building and maintaining environments
Experience working in cloud environments (AWS and/or GCP)
Familiarity with Kubernetes in production environments
Proficiency in at least one programming or scripting language (Python, Java, Bash, or similar), including working with existing codebases
