How you will make an impact:

As a Senior Engineer on the Cloud Platform team, your impact will be measured by the continuous improvement of our platform's reliability, scalability, and security posture.

- SLO Ownership & Error Budget Management: Take direct ownership of the established Service Level Indicators (SLIs) and Service Level Objectives (SLOs) for core platform services (e.g., latency, availability, error rate). You will manage and use the Error Budget as the primary drivers to prioritize reliability work
- 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.
- Drive Systemic Improvements: This role centers on hands-on engineering skill, technical leadership, and systemic reliability improvements within our complex, distributed multi-region platform.

What you'll do

- Kubernetes Platform Engineering

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.

- Traffic & Ingress Reliability

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.

- Infrastructure-as-Code at Scale

Demonstrate mastery in IaC to manage complex, multi-region architecture. Use tools like Terraform Cloud to build reusable modules, validate changes through policy-as-code, and establish safe multi-account patterns our teams can rely on.

- Security & Access Control

Drive a zero-trust posture by establishing service guardrails and access controls across the platform: This includes: implementing policy-as-code solutions,brokering least-privilege access for platform using cloud Identity and Access Management (IAM) best practices, and Integrating and managing identity providers to define Role-Based Access Control (RBAC) across environments.

- Reliability Engineering & Incident Leadership

Demonstrate strong diagnostic and incident-response leadership to rapidly isolate issues across clusters, networks, and workloads. Your ultimate responsibility will be to lead and drive systemic, long-term fixes and root-cause investigations, ensuring all necessary actions are taken to eliminate repeat failures .

- Collaboration, Influence & Mentorship

Guide and influence engineering teams across the organization through design reviews, operational best practices, and reliability-focused decision-making.
