  • Create repeatable VM provisioning pipelines and standardized system builds; support mixed Linux and Windows environments as required.

  • Support laboratory and research platforms, including LIMS infrastructure, data ingestion workflows, and Windows batch/integration scripts when needed.
  • Install, test, upgrade, and maintain research and enterprise applications across test and production environments (examples: LIMS, JBOSS-based systems, Appian, data analysis tools).
  • Provision and optimize storage access (NFS, S3) and integrate with highโ€‘performance storage solutions (Weka, VAST, EMC).
  • Manage Jupyter, R, and RStudio environments, including package management and researcher support.
  • Implement and maintain GitLab-based CI/CD pipelines, infrastructure-as-code, and version-controlled operational runbooks.
  • Ensure systems meet HIPAA, CAP, and ISO compliance requirements โ€” maintain documentation, change control, audit evidence, and traceability.
  • Provide senior-tier Linux/UNIX support to technical teams and researchers, mentor staff, and document operational best practices.
  • Operate independently across multiple concurrent efforts; adapt to evolving laboratory and research needs.

Required Qualifications

  • Advanced Python automation skills; strong Bash/shell scripting experience.
  • Hands-on Linux administration experience (RHEL preferred), including patching, security, and lifecycle management.
  • Proven experience managing onโ€‘prem Kubernetes platforms and Helm-based deployments.
  • Solid understanding of Apache Airflow, HashiCorp Vault, and workflow-driven automation.
  • Experience supporting DICOM-based medical or research imaging systems.
  • Working knowledge of NFS and S3 storage models and high-performance storage environments.
  • Demonstrated experience supporting regulated research or healthcare systems, with audit and compliance readiness.
  • Proficiency with GitLab repositories, CI/CD pipelines, and automation workflows.
  • Strong communication, documentation, and cross-disciplinary collaboration skills.

Preferred Qualifications
