You will manage and use the Error Budget as the primary drivers to prioritize reliability work</li> <li>Scale and HArden the Core Platform: Apply deep technical expertise in Kubernetes, AWS, traffic management, and Infrastructure-as-Code to scale and harden the foundational platform that powers Iterable’s product workloads. </li> <li>Drive Systemic Improvements: This role centers on <strong>hands-on engineering skill</strong>, <strong>technical leadership</strong>, and <strong>systemic reliability improvements</strong> within our complex, distributed multi-region platform.</li> </ul> <h4><strong>What you’ll do</strong></h4> <ul> <li><strong>Kubernetes Platform Engineering</strong><strong><br/></strong>Use your Kubernetes and AWS expertise to evolve EKS lifecycle, multi-tenant isolation, and regional consistency, ensuring clusters remain secure, performant, and predictable as we scale.</li> <li><strong>Traffic &amp; Ingress Reliability</strong><strong><br/></strong>Apply advanced knowledge of cloud-native traffic management, and API gateways to strengthen routing, authentication, rate-limiting, and secure communication protocols (like mTLS). This focus will dramatically improve both the reliability and security posture of the platform’s public and internal service access points.</li> <li><strong>Infrastructure-as-Code at Scale</strong><strong><br/></strong>Demonstrate mastery in IaC to manage complex, multi-region architecture.
