Role Overview

As a Platform Engineer, you will be part of the Platform team reporting directly to the Head of Engineering with technical guidance from the Lead Site Reliability Engineer (SRE). Your core responsibility will involve managing and enhancing our production infrastructure primarily hosted in AWS, featuring a Linux/Apache/PHP/MySQL environment alongside an evolving Kubernetes-based platform. Your daily tasks will include operating Kubernetes clusters (notably AWS EKS), troubleshooting deployment and infrastructure issues, upgrading systems, monitoring performance, managing capacity, and automating manual processes. Key tools in use include GitLab, ArgoCD, Temporal, and Datadog for deploying, monitoring, and managing background workflow processing. Your role will also extend to contributing towards the comprehensive operation of our AWS ecosystem under the Platform team's remit. Being accountable for live production systems means incident response and thoughtful change management are key, including participation in an on-call rotation.
