AI Engineer - Core

About Hilbert's AI

Hilbert develops a reasoning engine for navigating non-deterministic user behavior across data silos, transforming lengthy decision cycles into minutes through a fully agentic demand intelligence platform. The company serves Fortune 500 enterprises and brands like FreshDirect and Levain Bakery.

The role requires building production-grade AI systems end-to-end, from experimentation through deployment.

Key Responsibilities:

• Design and maintain AI-driven features serving enterprise customers
• Architect agent workflows using orchestration frameworks
• Own systems from experimentation to production deployment
• Build and improve evaluation pipelines for AI performance
• Collaborate cross-functionally with founding team and product/GTM partners
• Make engineering decisions under ambiguity; ship, learn, iterate
• Shape technical direction as the company scales

Core Technical Challenges:

• Intelligent retrieval combining RAG, graph-based approaches, and unified strategies
• Robust agentic workflows handling edge cases and escalation
• Systematic evaluation frameworks predicting real-world performance
• Agent-driven execution with human-in-the-loop safeguards

Required Qualifications:

• Strong software engineering fundamentals (clean, testable, production-ready code)
• Hands-on experience with LangChain, LangGraph, or equivalent agent frameworks
• Clear technical communication with both technical and non-technical stakeholders
• Ownership mindset; proactive problem-solving
• Comfort with ambiguity in evolving AI products
• Startup-speed execution and responsiveness

Strong Pluses:

• Evaluation pipeline design experience
• Backend engineering (APIs, services, infrastructure)
• RAG, vector databases, or LLM-powered systems
• Early-stage startup experience

Compensation: Competitive salary + equity package, commensurate with experience. Performance-based bonuses tied to project milestones and customer impact.
