3–5 years shipping software

Who we are

Every brand deserves their perfect store. PSG is the AI-native sales agency and brokerage that delivers it.

The $10B+ CPG sales industry is stuck in 2005: opaque, manual, and bogged down in data work that should be automated. We're building the operating system to fix it. Our platform deploys an army of autonomous agents to handle the grunt work (category reviews, promo planning, deck building) so our Account Executives can do what actually moves product: relationships, strategy, and winning shelf space. Come build with us.

Founding team out of Bain & Company, Google, Advantage Solutions, and PepsiCo.

The role

You're building alongside the CTO. Your fingerprints will be on every architectural decision we make for the next decade.

Agent infrastructure The harness orchestrating agents that 10x our sales team. This is the product.

Data pipelines Retailer POS, syndicated data, and brand first-party data. Messy, multi-source, high-volume. You'll architect how it fits together.

Backend Cloud Run, Firestore, BigQuery, Firebase Auth, multi-tenant isolation. The infra that keeps client data secure and the platform fast.

Frontend when needed Most UI work is handled, but you should be comfortable in React + TypeScript.

What we're looking for

  • 3–5 years shipping production software, ideally including a high-caliber eng org (FAANG, top startup, or equivalent).
  • AI-native by default. Claude Code or Codex is in your daily loop. You think in agents, tools, and context.
  • Strong backend chops: data models, migrations, auth, security, deploys.
  • Bias toward shipping. Working by Friday beats perfect by next month.
  • Autonomy. "Solve client data ingestion" becomes architecture, tickets, shipped code. You don't wait.
  • Grit. Startups have bumps. You find a way through.
STRONG SIGNALS

GCP depth · ETL and data warehousing · Cybersecurity background · Claude Agent SDK or MCP · CPG or retail data exposure · Full-stack TypeScript · Early-stage startup time
