AI in this role
Build high-scale audio processing infrastructure and integrate clinical AI capabilities into communication networks.
Overview
Corti is the frontier lab for clinical-grade AI, building world-leading models and infrastructure for the realities of healthcare.
Our technology powers healthcare’s most ambitious software, from EHR vendors and virtual care platforms to the health systems that care depends on. We work with builders ranging from fast-moving startups to global healthcare enterprises, helping them bring clinical AI into real-world care.
Healthcare is full of problems where AI has to do more than simply work. Clinicians are overwhelmed by documentation. Coding errors, backlogs and denials cost health systems billions. And the specialist expertise patients need is not always available when they need it.
We build AI specifically for these environments, trained on real patient interactions, validated against real outcomes, and designed to perform where accuracy, trust and reliability matter. If you want to help define how AI is built for healthcare, you belong at Corti.

Integrate AI capabilities into low-latency, high-throughput audio processing pipelines.
Collaborate with the Platform Engineering team with a commitment to engineering excellence to ensure system reliability and scalability.
Hands-on development of an innovative solution where design choices matter
Work with colleagues in design and code reviews
