Senior AI Platform Engineer – HexCore & Eval Systems

The Role:
We are seeking a Senior AI Platform Engineer to own the core platform layer that powers every AI agent in production — from multi-tenant agent configuration and schema architecture, to data pipeline contracts, evaluation harnesses, and customer onboarding automation.
This role sits at the intersection of backend platform engineering, LangGraph-based orchestration, and AI evaluation systems. You won't just build features — you'll own the infrastructure that makes all features possible: the agent orchestration graph, the customer configuration schema, end-to-end conversation logging, automated eval pipelines, and the scripts that deploy new customers in under 30 minutes.
If you love owning systems that other engineers depend on, ship at high velocity across a wide surface area, and take pride in leaving codebases cleaner than you found them — we want to hear from you.
