Job Application for Contract Senior DevOps Engineer at Sirona Medical

New

At Sirona Medical we’re building tools for physicians to work as fast as they can think. Many billions of patient images are acquired each year in the U.S., and nearly all of them are reviewed and diagnosed by a radiologist. In fact, 80% of healthcare data flows through radiology IT systems, and radiologists are among healthcare’s most tech-savvy and influential physicians. But they desperately need better, user-friendly software that cuts clicks and optimizes diagnostic time. Sirona is building a modern cloud-native and AI-powered operating system (“RadOS”) that unifies radiology IT onto a single, streamlined workspace. We’re a San Francisco, CA-based software company (with employees working from all over the world) founded on a deep understanding of both the practice and business of radiology.

A willingness to deeply understand all aspects of the stack.
Strong expertise in DevOps, with the ability to investigate and optimize any part of the stack.
A focus on simplicity and scalability, coupled with a collaborative, agile mindset and eagerness to learn.
