✨ AI Summary

raylu, a New York-based AI company, is hiring a product-oriented Senior AI Engineer to build and productionize agentic LLM systems. The role focuses on orchestration, tool calling, evals, and reliability rather than fine-tuning, with a stack centered on LLMs, APIs, and workflow engines like Temporal. Requires deep expertise in agentic systems, engineering-first debugging, and product iteration; full-stack experience is a plus. Fully in-office in Midtown Manhattan (no remote), with salary $165K-$250K plus $100K-$200K equity, and perks like paid lunches, 401k match, and wellness benefits.

Position Summary
We’re hiring a product-oriented Senior AI Engineer who loves tinkering with LLMs and shipping real agent systems. We spend less time on fine-tuning and more on orchestration, evaluation, and reliability—so agents do real work safely, quickly, and repeatedly.

What we’re looking for
  • Agentic systems: Function/tool calling, multi-step planning, routing, memory, and retrieval.
  • Engineering first: You can wire up services, craft eval harnesses, and debug latency/cost at scale.
  • LLM breadth: Comfortable comparing models/hosts, prompt strategies, and guardrail techniques.
  • Product focus: You instrument outcomes, run A/Bs, and iterate to improve task success rates.
  • Opinionated: Deep level of understanding of the technological landscape, making both high level system and granular code design decisions based on understanding rather than preference - diving deep on unknown patterns in order to build the best product.

Responsibilities
  • Design, build, and productionize agent workflows end-to-end (APIs, tools, evals, monitoring).
  • Create safety, cost, and latency controls; build dashboards and alerts for reliability.
  • Partner with product/design to invent new interaction patterns and ship them fast.
  • Document patterns and mentor engineers on best practices for LLM-powered features.

Nice to have
  • Experience with workflow engines (e.g., Temporal), comfort in full stack engineering

Logistics:
  • Compensation: $165K - $250K salary, $100K-200K equivalent in new hire equity (4 year vest)
  • Location: New York City. We are a fully in-office team working out of Midtown Manhattan Monday through Friday. We allow for WFH days when anyone is traveling, but we do not allow for permanent remote work.
  • Benefits:
    • Generous health, dental, and vision insurance
    • 401k with 3% automatic contribution (no vesting)
    • Paid Lunches
    • Wellness and Citi Bike benefit
