Senior Cloud Infrastructure Engineer; AWS

Verisys is looking for a hands-on Senior Cloud Infrastructure Engineer with deep AWS expertise to help build, secure, and scale the infrastructure behind our healthcare credentialing platform. Our environment is primarily Windows-based, and you will be our subject matter expert for Linux, our on-premises Nutanix environment, container platforms (Rancher and Amazon ECS Anywhere), SMTP relay, and SSL/TLS certificates. This is a remote role with high ownership, focused mainly on Dev Ops and cloud engineering with a meaningful systems administration component.

This is a generalist role on a small team: you will move between cloud engineering, systems administration, and whatever the business needs next, so comfort with shifting priorities matters as much as any single skill.

Please note this is a remote opportunity, but you MUST live in one of the following states to be considered:
AZ, CO, FL, GA, IL, IN, KS, KY, MD, MA, MO, NC, OH, OK, PA, TN, UT, VA, WI

• Design, build, and operate secure, highly available AWS infrastructure (EC2, VPC, IAM, ECS, S3, RDS, Route 53, Cloud Watch, Systems Manager) following the AWS Well-Architected Framework, with an eye on security, cost, and disaster recovery.

• Manage infrastructure as code (Cloud Formation) and support CI/CD pipelines for container builds and deployments.

• Run containerized workloads on Amazon ECS and ECS Anywhere, and administer Rancher native Cattle clusters.

• Serve as the Linux subject matter expert: provisioning, hardening, patching, performance tuning, and troubleshooting across physical, virtual, and cloud servers.

• Administer our Windows Server environment, including Active Directory, Group Policy, DNS/DHCP, and IIS, on-premises and on EC2.

• Administer our on-premises Nutanix environment using Prism Element and Prism Central, including cluster health, AHV virtual machine management, capacity planning, upgrades, and data protection.

• Automate configuration and patching with Python, Power Shell, Bash, and AWS Systems Manager.

• Own our SMTP relay infrastructure (Postfix and/or Amazon SES), including SPF, DKIM, DMARC, TLS, and deliverability troubleshooting.

• Own SSL/TLS certificate renewals and installation across IIS, Linux web servers, Postfix, and AWS (ACM, load balancers), automating renewals wherever possible.

• Maintain monitoring, logging, and alerting, participate in on-call, and support HITRUST and SOC 2 compliance.

• Deep, hands-on AWS experience and strong knowledge of AWS security, networking, and best practices.

• Expert-level Linux administration and strong Windows Server administration skills.

• Hands-on experience with Rancher-native Cattle clusters and Amazon ECS / ECS Anywhere.

• Strong hands-on experience administering Nutanix hyperconverged infrastructure, including Prism Element, Prism Central, and AHV.

• Proficiency with Cloud Formation, and Power Shell/Bash scripting; strong Python skills are a major plus.

• Working knowledge of SMTP relay configuration and end-to-end SSL/TLS certificate management (CSRs, chains, OpenSSL, PEM/PFX).

• Solid networking fundamentals: TCP/IP, DNS, load balancing, VPN, and security groups.

• Excellent communication skills and the ability to work independently in a remote environment.

• Adaptable and comfortable wearing many hats, with the ability to shift between cloud, systems, and support work as priorities change.

• 5+ years in Cloud Engineering, Dev Ops, SRE, and/or systems administration, including 3+ years supporting production workloads in AWS.

• Bachelor's degree in a related field or equivalent practical experience.

• Strong Python development skills for automation and…
