Senior AI Engineer

Description:

The Tasks API team builds Nimble's frontier agentic products - systems that turn arbitrary web data sources into insights and structured data for our customers, running in production today.

We're hiring a senior engineer who combines strong backend fundamentals with genuine hands-on experience in agentic AI.

• Build and own agents end-to-end - from architecture and harness design to production deployment and continuous improvement.
• Design evaluations that drive real quality gains: own the datasets, metrics, and experiments behind our agents.
• Build the agentic infrastructure the rest of the team builds on top of - reliable, scalable, production-grade.
• Bring product sense and connect what we ship to what customers actually need.

• 10+ years of backend experience, with scale experience - you've built systems that serve real external users and know how to keep them running.
• 2+ years of hands-on experience in an agentic product team - you've shipped meaningful LLM-powered products in production, not just experimented.
• Deep familiarity with LLM concepts: prompting, tool use, structured output, retrieval, evals, multi-step workflows.
• An analytical mindset - comfortable with performance analysis, optimization, and reasoning about non-deterministic systems.
• Proven ability to deploy AI to production - you know what breaks and how to prevent it.

Advantage

• Data science background.
• Experience with agentic frameworks (LangChain, LangGraph, etc.).
