GTM AI Engineer

Stack

Responsibilities

• ▹Alpha-to-production ownership - take newly built agents from working v1 to production-ready: write evals, harden prompts and tool definitions, refactor prototype scaffolding into clean, production-quality code
• ▹Observability & stability - instrument tracing, logging, and monitoring across the agent fleet so regressions are caught before the 120+ GTM users do
• ▹Deployment & infrastructure - stand up and maintain the pipelines that get agents into users' hands without surprises, owning environment parity and release hygiene on the GCP stack
• ▹Database administration - own how agents read from and write to databases, safely and at scale
• ▹Fleet maintenance - monitor agent behavior in production, triage issues, ship a steady stream of improvements
• ▹Partner closely with the GTM AI team to free up agent builders to stay in their zero-to-one wheelhouse
• ▹Bring an outside point of view - flag what was built wrong, backed by a plan to fix it

Requirements

• ▹4+ years in software engineering, platform/infrastructure engineering, or a similarly technical role, ideally at a B2B SaaS company
• ▹Comfort working in the terminal daily, with a real GitHub PR-and-deploy workflow
• ▹Cloud hosting experience - Kubernetes, VMs, or equivalent; Google Cloud experience strongly preferred
• ▹Experience with how agents interact with and edit databases, including hands-on database administration
• ▹Familiarity with LLM-based application development: prompt engineering, tool/function calling, evals, and modern agent frameworks
• ▹Ability to prompt AI tools correctly, review their output critically, and direct them to QA their own work
