Senior AI Engineer — Production LLM & Agent Systems

Hilbert; United States; Remote; USD 140,000 - 190,000; Full time

Job summary

Hilbert is building a reasoning engine to navigate non-deterministic user behavior across data silos. We seek an AI Engineer to own core AI stack pieces, from prototype to pipeline to product, with startup urgency and ownership.

You will design agent architectures, build evaluation systems, and balance accuracy, latency, and cost in production. Expect fast shipping amid evolving specs and clear internal communication.

Qualifications

• 4+ years of production software engineering (APIs, services, data infra) ownership and on-call.
• 2+ years building LLM or agent systems deployed to production.

Responsibilities

• Own the evaluation layer for agents: harnesses, metrics, regression gates, and human-in-the-loop review.
• Architect and implement agent workflows using LangChain, LangGraph, or equivalents with memory, routing, registries, and recovery paths.
• Own systems from experimentation through production: tracing, monitoring, latency, and cost-per-task budgeting.
