The Role

You’ll build and run Cortex, the core AI architecture behind Q, and the services that sit on top of it: automated AI audits, patient simulators, retrieval (RAG), and the escalation agents that take over in red‑guardrail situations. This is a backend role first. The job is to make our AI systems reliable, fast, and observable in production, not to invent new ML. You own the software underneath the agents.

What You’ll Do

• Design and maintain robust, modular backend systems using clean architectural (SOLID) principles to ensure long‑term maintainability, scalability and flexibility as the agentic stack evolves.
• Own Cortex end‑to‑end: architecture, API design, service boundaries, reliability targets, and proactively managing failure modes.
• Build the platform services around it. The automated audit and eval pipeline, patient simulators for testing agents at scale, and the retrieval layer.
• Write fast, well‑tested Python s...
