Senior Systems Administrator

Garner’s mission is to transform the healthcare economy, delivering high-quality and affordable care for all.

We are fundamentally reimagining how healthcare works in the U.S. by partnering with employers to redesign healthcare benefits using clear incentives and powerful, data-driven insights. Our approach guides employees to higher-quality, lower-cost care, creating a system that works better for everyone. Patients achieve better health outcomes, employers spend healthcare dollars more effectively, and physicians are rewarded for delivering exceptional care rather than performing more procedures.

Garner is one of the fastest-growing healthcare technology companies in the country. Our products are trusted by the most sophisticated employers and providers in the industry, and we are building a team of talented, mission-driven individuals who are motivated to make a meaningful impact on healthcare at scale.

We are seeking an exceptional Senior Systems Administrator to join our Business Technology team as a key member of our growing organization. This is an opportunity to directly shape the future of Garner’s IT infrastructure by owning and improving the systems, processes, and controls that enable us to scale securely and efficiently.

In this role, you’ll manage core enterprise platforms and networks, ensure consistent and compliant service delivery, and drive initiatives that strengthen our security and operational foundation. You’ll play a critical role in implementing frameworks such as Role-Based Access Control (RBAC), maintaining HITRUST and SOC 2 readiness, and optimizing system performance across Garner’s environment.

This position is ideal for someone who thrives in a fast-paced, high-growth company and enjoys building scalable systems and processes that support both operational excellence and regulatory compliance.

This role will be based in our New York City office. You must be willing to work in the office 3 days per week on Tuesday, Wednesday and Thursday.
