Senior Systems Engineer (Contract)Remote

Job: Expert Intersystems Platform Administrator

Team: Integration Platform

Type: Senior level

Location: 100 percent remote within the United States (Preference to candidates on the west coast)

Work hours: Standard 8 hour day. Every third week includes level 2 on call coverage. West Coast hours preferred to align with follow the sun support.

Why this role matters

Own the reliability, performance, and always on availability of Tier 1 Intersystems platforms that power mission critical clinical and business operations. You will support an ongoing Epic migration, help modernize a large scale environment with 130 plus servers, and ensure HA and DR across data centers.

What you will do

• Provide senior level support for Ensemble, HealthShare HIE, and IRIS for Health with participation in a rotating level 2 on call schedule. Level 1 handles most incidents and escalates as needed.
• Manage and monitor multi environment Intersystems infrastructure across AIX and Linux. Focus is the application and database stack rather than OS administration.
• Perform advanced troubleshooting, performance tuning, system health checks, and capacity planning for Cache and IRIS.
• Design, develop, and maintain ObjectScript automation including installer and operational utilities.
• Review, standardize, and maintain ZAUTHENTICATE routines for secure authentication.
• Design and maintain role based access and security administration that maps Intersystems roles to Active Directory for single sign on.
• Build and configure new instances, edges, namespaces, and environments. Maintain multi terabyte Cache and IRIS databases.
• Lead and support the migration from AIX and Cache to Linux and IRIS. You will prepare platforms and namespaces rather than migrate interfaces.
• Execute change management for production work, including scheduling and documentation.
• Initiate and manage vendor cases with the Intersystems WRC including log collection and follow through to resolution.
• Create and maintain clear technical and operational documentation. Participate in daily Scrum and regular planning ceremonies.

What you bring

• 3 plus years hands on administration of Intersystems Cache, HealthShare HIE, and IRIS.
• Strong ObjectScript skills for operational automation and installer scripting.
• Direct experience with ZAUTHENTICATE and authentication workflows.
• Expertise in security administration for Cache and IRIS including role creation and access control scripting integrated with Active Directory.
• Proven support of mission critical 24x7 platforms with HA and DR including data center failovers.
• Solid troubleshooting, customer focused communication, and risk aware decision making in production.
• Experience with Unix based systems including AIX and Linux. Deep OS admin is not required as a separate team manages compute and storage.
• Familiarity with change management and version control practices.

Nice to have

• Background with healthcare integration platforms and HIE environments.
• Exposure to Epic data flows or integration environments. Epic experience is a plus, not required.
• Experience operating at scale including large servers up to 40 CPUs and Cache or IRIS databases approaching 16 TB.
• Cloud exposure is acceptable but not required for this role.

Work setup and schedule

• Remote first role across the United States.
• Preference for West Coast hours to complement East Coast and India coverage and to provide late day level 2 support without after hours calls.
• Standard 8 hour day. Every third week includes on call responsibilities that align with your shift.
