## Description

As a Senior Applied AI Engineer, you will design, build, and deploy production-ready agentic AI systems that operate reliably in demanding environments.

You will take ownership of system architecture, multi-agent workflows, retrieval and reasoning pipelines, model integration, and deployment strategies. The emphasis is on engineering robust, scalable systems that deliver dependable outcomes in real-world use cases.

This is a senior, hands-on engineering role suited to someone who builds AI products from first principles rather than simply integrating existing tools.
