Applied AI Engineer

About the role

You will own the agentic infrastructure at a seed‑stage AI startup building the foundational layer for AI‑native service operations. This means designing and shipping the systems that let agents execute reliably in production, retain months of client context, and know when to hand off to a human.

Key responsibilities

• Build and maintain core infrastructure that enables agents to execute tasks reliably across dozens of iterations.
• Design and implement memory systems that retain months of client context from messy, real‑world operational data.
• Develop evaluation harnesses that teams trust to make production shipping decisions.
• Own the full loop: build it, measure it, break it, fix it, and make it learn.
• Ship agent systems for real customers and iterate directly based on production feedback.
• Contribute across infrastructure, orchestration, customer collaboration, and early hiring as the team grows.

Required profile

• 3+ years shipping LLM agents that ran unattended in production for real users, understanding that the model is the easy part.
• Hands‑on experience building eval harnesses used for production deployment decisions.
• Experience with retrieval and memory systems that work on real, messy operational data, not demo RAG pipelines.
• Strong Python proficiency for building production systems end‑to‑end.
• Experience with agent orchestration, workflow management, or reliability patterns such as failure recovery and retry logic.
• Experience building agent tooling, frameworks, or libraries (strong plus).
• Experience with human‑in‑the‑loop or approval workflow systems (plus).
• Track record of intensity and execution; open‑source contributions or a founded technical project are a bonus.
