Senior Backend Engineer, Audio Processing

We are looking for an engineer passionate about building the next generation of high-scale audio processing infrastructure for communication centers that form a vital part of our critical infrastructure, including emergency dispatch centers and hospitals. You will be responsible for integrating AI capabilities into environments dominated by network protocols like SIP and SIPREC, ensuring robust and scalable performance at the heart of life-critical operations.

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.
