At UnitedHealth Group and Optum, we want to make healthcare work better for everyone. This depends on hiring the best and brightest. With a thriving ecosystem of investment and innovation, our business in Ireland is constantly growing to support the healthcare needs of the future.

With our hands at work across all aspects of health, we use the most advanced development tools, AI, data science and innovative approaches to make the healthcare system work better for everyone.
The EHR System Specialist for Ancillary Clinical Applications is responsible for the support, configuration, and optimization of ancillary systems integrated with the core EHR platform, as well as standalone clinical applications used across the healthcare enterprise. This role ensures system reliability and performance by providing end‑user support, troubleshooting and resolving system issues, and proactively enhancing application functionality and workflows. The position focuses on delivering efficient, high‑quality solutions that meet operational needs while driving continuous improvement in system usability and client satisfaction.
We are interested in individuals with solid technical and/or application support experience, preferably with exposure to healthcare systems such as Radiology Information Systems (RIS), Laboratory Information Management Systems (LIMS), Pharmacy systems or other ancillary platforms. While a clinical background (e.g., laboratory, radiology, and pharmacy technicians, or nursing) are not required, it is considered a valuable asset. Solid candidates will be able to demonstrate self‑motivation and team collaboration. Given the cross‑disciplinary nature of this position, solid communication and problem‑solving skills are critical. Our team is committed to cultivating a culture of diversity and inclusion that empowers both our company and our clients – and as our new EHR System Specialist (Ancillary Clinical Applications), you will be an integral part of advancing this mission.
There will be job‑related training where there may be an expectation to work adjusted hours, depending on trainer location/availability. Following this, local hours would be standard with a need for some flexibility when working with US clients.
Careers with Optum offer flexible work arrangements, and this role operates in a hybrid model, with 3 days based in our Letterkenny office and 2 days remote working from home.
