Senior Backend Developer - AI

About UpHill

At UpHill, our mission is to increase clinical capacity so healthcare professionals can focus on what matters most - the patients. Healthcare teams are either stretched thin by work that can be automated or weighed down by waste that can be avoided. UpHill's intelligent automated platform uses hospital data and patient conversations to turn chaos into useful and efficient interactions.

We build conversational AI agents, intelligent clinical pathways, and care orchestration tools that empower clinicians to work at their full potential - deployed across leading hospitals in Europe, with 100K+ lives impacted and over 1 million clinical interactions mediated. UpHill Route is a certified Class IIa Medical Device.

We're a team of curious and creative people who believe technology should enhance - not replace - the work of healthcare professionals. If you're excited about making a real impact in one of the most meaningful industries in the world, you just might be an Uphiller.

Today we're looking for a Senior Backend Developerto join our AI team and help us build the next generation of AI infrastructure for healthcare - powering clinical agents that interact with patients in real time, triage symptoms intelligently, and support clinical decision-making at scale.
