Senior AI Engineer

Overview We are on a mission to ensure everyone has access to medical expertise, no matter where they are. Half the world still lacks access to quality healthcare. Even in advanced systems, outcomes are uneven, and clinicians are overwhelmed. Medical knowledge grows faster than human capacity can keep up. Corti exists to close that gap. Our AI platform expands access to medical expertise, reducing errors, restoring time to clinicians, and making care more affordable, accessible, and human again. There is no quality healthcare without a quality dialogue, and no reliable AI without a strong foundation. Help us build both. Why Corti? Corti is the frontier lab for clinical-grade AI. We build world-leading models and infrastructure that power healthcare's most ambitious software - from EHR vendors and virtual care platforms to the health systems that care depends on. Today, Corti serves over 100 million patients annually, including the NHS. Our flagship model, Symphony, is trained and validated on real clinical data from real patient interactions, and powers the clinical and administrative work that healthcare runs on. We power the builders who are redefining how healthcare works, from startups creating new patient experiences to enterprises modernizing the systems that care depends on. If you believe that AI purpose-built for medicine will define the next century of healthcare, you belong at Corti. The Role As a Senior AI Engineer focused on agentic framework, you will focus on building LLM-powered systems and agentic workflows that power core product capabilities at Corti. You will work on building strong validation practices, and deploying low-latency inference services that are dependable in real-world conditions. You will work at the intersection of AI, product, and engineering, designing and implementing systems that leverage large language models, retrieval architectures, and context-aware agents to solve complex real-world problems. This is a hands-on engineering role for someone who enjoys building production systems—not just experimenting with models. What you’ll be doing Design and build LLM-powered product features used in production. Develop agentic workflows and frameworks that coordinate multiple AI components. Implement RAG (Retrieval-Augmented Generation) architectures using embeddings and vector search. Build systems for prompting, context engineering, and tool usage. Develop evaluation frameworks to measure LLM and agent performance. Work closely with product and platform teams to turn AI capabilities into reliable, scalable product features. Continuously improve system reliability, latency, and cost efficiency of AI pipelines. Technologies you may work with Apache Kafa NVIDIA Triton Inference Server FastAPI for ML APIs and services Go for backend services Kubernetes for deployment and operations Common MLOps tooling for experiment tracking, model versioning, and monitoring What you bring Strong programming skills in Python and the ability to contribute to production-grade codebases. Hands-on experience in LLMs, including at least some of the following: Training, finetuning, or post-training transformer-based models. Building or operating LLM inference services in production, including performance work. Experience with embeddings, vector databases, and semantic search. Practical experience implementing RAG architectures. Designing robust evaluations for agent workflows and generative systems, including metrics, error analysis, and human evaluation methods. Experience building production-grade ML systems that can be deployed and operated, including pipelines, CI and CD practices, and monitoring. Strong product mindset with the ability to translate ideas into working systems Clear communication and collaboration skills across research, engineering, and product. A Master’s degree in computer science, engineering, mathematics, statistics, physics, or a related field, or equivalent professional experience. Nice to have: Experience with healthcare data, clinical NLP, privacy and safety considerations. Experience with Go.
