About the Company

A San Francisco–based, seed-stage AI startup helping enterprises move AI from prototype to reliable production — embedding with customers, auditing their operations, and building the agents, integrations, and workflows that transform how those businesses run. The founding thesis: the hardest part of enterprise AI isn’t the model, it’s deployment, reliability, and trust.

Founded 2026 · 11–50 people · Industry: AI Tools

The Role

Lead the platform’s technical direction — design the architecture, set engineering standards, and own the build-vs-buy decisions that determine the company’s trajectory. This is the person defining the system, not a senior IC inside someone else’s org. Direct path to CTO.

What you’ll be doing

  • Own the technical architecture: agent orchestration, process-mining infrastructure, diagnostic pipelines, and the control plane that turns audit outputs into deployed AI systems
  • Architect compound AI systems running inside Fortune 5000 environments: multi-step agents, retrieval pipelines, evaluation frameworks, human-in-the-loop governance
  • Set the engineering pace — the company ships to production weekly, not quarterly; drive velocity, cut scope ruthlessly
  • Recruit, mentor, and lead engineers; set code-review standards, establish process, and build a team that scales from 5 to 50
  • Bridge research and production: stay current on foundation models, agent frameworks, inference optimization, tool use, and long-context reasoning, and translate what’s useful into production

Tech stack: Agent orchestration, retrieval pipelines, evaluation frameworks; infrastructure depth (Kubernetes, distributed systems, cloud) a plus.

Requirements

  • Production AI/ML systems: inference, orchestration, evaluation, monitoring
  • High agency, ownership mentality
  • SF Financial District, 5 days in-person

Green Flags

  • Real, deep understanding of how scale actually works in production.
  • Can architect on a whiteboard without leaning on slides.
  • Has shipped production systems they personally designed.
  • Strong opinions, easily updated when shown they’re wrong.
  • Visible curiosity about agent and AI infrastructure specifically.
  • Capable of being CTO in a few months

Red Flags

  • Title says “staff” but they’ve only ever consumed abstracted infra.
  • Can’t code live in the interview.
  • Hand-wavy on scalability (“we’d just use Kubernetes”).
  • Ego that won’t compress to a 10-person team.
  • Coast mode from a comfortable big-tech role.
  • No background at a top AI lab or as a founding/senior engineer at an AI-native startup.
  • Significantly outside 6+ years engineering with 2+ years in a staff, principal, or founding role (years of experience isn’t a hard filter — recent company quality and demonstrated output matter more).

Why Join

  • Founding-team scope and ownership of the entire technical vision, with a direct path to CTO
  • Build a platform, not features — every client deployment compounds the product
  • 100% production deployment rate with immediate, measurable impact
  • Direct access to Fortune 5000 decision-makers
