Cloud Infrastructure Engineer – AWS & ML Tooling

Position Overview

Zelis is seeking a hands-on Infrastructure Engineer to help scale and mature our cloud and automation environment. This role sits within our Data Intelligence group and works closely with the Cloud Center of Excellence (CCOE) to support production infrastructure needs for data, analytics, and ML-based applications on AWS. While this is not an MLOps engineer role, familiarity with services like Sage Maker and the ability to support ML workflows from an infrastructure standpoint is important.

Your core focus will be automation, deployment pipelines, cloud networking, security best practices, and ensuring the resilience and performance of our AWS-hosted environments.

• Build and maintain AWS infrastructure using Terraform or Cloud Formation (IaC)
• Manage containerized applications using ECS and help optimize Sage Maker infrastructure used by ML teams
• Design, monitor, and improve networking architecture including VPCs, security groups, load balancers, and DNS
• Maintain and enhance CI/CD pipelines to support automated testing, deployment, and rollback
• Collaborate with engineering teams to optimize deployment flows and reduce friction across environments
• Implement infrastructure security and support compliance efforts (HIPAA, SOC2, etc.)
• Participate in cost optimization reviews and system uptime monitoring, troublehsooting as needed

• 5+ years of Dev Ops, Infrastructure, or Site Reliability Engineering experience in a cloud-native production environment
• Deep expertise with AWS services, particularly ECS, EC2, VPC, IAM, and Cloud Watch
• Experience managing ML-adjacent infrastructure, particularly AWS Sage Maker
• Strong background in infrastructure as code (Terraform, Cloud Formation)
• Comfortable writing deployment and automation scripts in Python, Bash, or Ruby
• Hands-on experience implementing secure, compliant cloud environments

• AWS Solutions Architect Associate or Professional certification
• Experience migrating legacy workloads to AWS
• Familiarity with Git Hub Actions, Jenkins, or other CI/CD tools
• Understanding of supporting analytics and ML teams from an ops perspective

• Not a data science or MLOps role (though you'll support ML infrastructure)
• Not a high-level strategic platform architect
• Not focused on theoretical platform ownership or innovation fluff. This is a practical, engineering-first role focused on well-structured, scalable infrastructure and automation in AWS.
