Lumexa Imaging is one of the country's largest providers of outpatient medical imaging. With over 5,000 team members and more than 185 outpatient imaging centers across 13 states, our team conducts more than 4 million outpatient studies annually. We are the partner of choice for health systems and radiologists, delivering best-in-class clinical excellence, operations, and state-of-the-art technology across our platform.

We are seeking an experienced Senior Cloud Engineer with deep expertise in public cloud Infrastructure ‑ ‑ ‑ as ‑ a ‑ Service (IaaS) across AWS and Microsoft Azure, with strong skills in cloud networking, identity, automation, and platform engineering. The ideal candidate will excel in designing, deploying, and optimizing scalable cloud environments, with a strong emphasis on virtual network architecture (AWS VPC / Azure VNet), inter ‑ network connectivity, cloud routing, private service endpoints (AWS Private Link / Azure Private Endpoints), DNS (Route 53 / Azure DNS), and hybrid network integrations using VPN and dedicated circuits (AWS Direct Connect / Azure Express Route).

This role requires hands ‑ on experience implementing secure, high ‑ performance solutions using core cloud services such as compute (EC2 / Azure VMs), identity (IAM / Azure AD), serverless (Lambda / Azure Functions), API management (API Gateway / Azure API Management), monitoring (Cloud Watch / Azure Monitor), logging (Cloud Trail / Azure Activity Logs), object storage (S3 / Azure Blob), relational databases (RDS / Azure SQL), and load balancing (ELB/ALB/NLB / Azure Load Balancer & Application Gateway).

The engineer will leverage cloud ‑ native networking and security controls — including security groups / NSGs, NACLs / Azure Firewall rules, AWS Network Firewall / Azure Firewall, WAF (AWS/Azure), and DDoS protection (AWS Shield / Azure DDoS Protection) — to build resilient, well ‑ architected systems aligned with best practices.

The Senior Cloud Engineer will play a key role in modernizing our infrastructure, improving network resiliency, and driving automation through services like Cloud Formation / Azure Resource Manager (ARM), Terraform, Systems Manager / Azure Automation, and AWS Config / Azure Policy.

• Automate provisioning, configuration, and operational workflows using AWS Cloud Formation, Azure ARM/Bicep, Terraform, Ansible, and other infrastructure‑as‑code tools.
• Monitor system health, analyze performance metrics, and conduct capacity planning using Cloud Watch / Azure Monitor, ensuring reliable and efficient cloud operations.
• Implement and enforce cloud security best practices, including IAM / Azure AD RBAC governance, network segmentation, encryption, and compliance with frameworks such as HIPAA and Sarbanes‑Oxley.
• Troubleshoot complex cloud infrastructure and networking issues across AWS and Azure, performing root cause analysis and driving long‑term remediation.
• Continuously evaluate emerging cloud services, tools, and architectural patterns across AWS and Azure to improve reliability, security, and operational efficiency.
