Staff Software Engineer, Agentic Platform

250k – 270kSan Francisco, CANew York, NYML EngineeringHybrid7+ YOE
Summary

Senior individual contributor architecting and scaling agentic LLM systems that turn messy manufacturing data into reliable root-cause insights. Owns orchestration, retrieval, evaluation, and guardrails for non-deterministic production systems.

About the role

Key Responsibilities

  • Own technical architecture for agentic systems—orchestration, tool use, memory, retrieval, evaluation, observability, and guardrails
  • Build and harden the reasoning layer and infrastructure that take customer data from ingestion through agent-driven reasoning to root-cause insight
  • Establish rigorous evaluation and testing for non-deterministic systems—measuring agent accuracy against expert-validated ground truth
  • Partner across Engineering and Product to shape the technical vision and roadmap for the agent platform
  • Raise engineering standards through code review, design docs, and technical direction
  • Mentor engineers on agentic patterns and system design

Requirements

  • Minimum 7+ years of software engineering experience, with recent, hands-on focus on building agentic systems (LLM orchestration, tool/function calling, multi-step and multi-agent reasoning, retrieval and context engineering, and interoperability protocols such as MCP)
  • Demonstrated ability to design and own complex distributed systems, ideally in data-intensive B2B SaaS environments
  • Hands-on fluency with the modern agentic stack and strong intuition for failure modes of non-deterministic, LLM-driven systems
  • Experience turning messy, heterogeneous real-world data into something a model can reason over reliably
  • Track record of technical mentorship
  • Strong executor in fast-paced environments who can balance shipping MVPs with production-grade systems

Nice-to-Haves / Culture Fit

  • Thrives in early-stage companies
  • "Data First" philosophy
  • Comfortable with ambiguity and fast-moving situations
