Job Description:
About Luminai Healthcare operations have always depended on
people to bridge the gaps that technology couldn't. It relies on
complex manual work to carry out critical internal processes, yet
most health systems don’t have enough resources to properly
automate these tasks, leaving them stuck in outdated,
labor-intensive SOPs. Luminai structures the chaos, automates the
manual handoffs, and deploys end-to-end workflows across every
system, providing the integrated intelligence layer to improve
processes over time. By delegating to autonomous AI systems those
mission-critical workflows that previously expended valuable human
time, Luminai allows doctors and administrators to do what they do
best: Focus on Patients. We’ve raised significant amounts of
capital from the best Silicon Valley VCs: General Catalyst, Peak XV
(fka Sequoia India), YCombinator, as well as from investors
including Kevin Weil (Chief Product Officer at OpenAI), Arash
Ferdowsi (co-founder of Dropbox), Katie Stanton (former VP Global
Media, Twitter), and CEOs of companies such as Flexport, Notion,
Front, Ramp and Twitch. About the Role As a Staff Software
Engineer, you will play a foundational role in designing,
implementing and spearheading the core platform development. The
