About the Company

A Warsaw-based startup building the personal AI category - not entering an existing market, but creating a new one. Their product is an always-on AI agent that handles the mundane tasks of everyday life: groceries, appointments, job hunting, and whatever else gets in the way of living well.

By 2027, they believe everyone will have a personal AGI working for them around the clock. They're building it now, from Warsaw, with Silicon Valley intensity.

The founding team is 3 people. They're looking for the next one.

About the Role

As a Founding Engineer, you'll be one of the first technical hires shaping the core product and infrastructure. You'll work on hard, unsolved problems at the intersection of agentic AI and consumer software - with full ownership and no permission required.

This is a 6-7 days a week, 10-12 hours a day role. The team is explicit about this. If you want to build a global, rapidly growing company without moving nine time zones from home, this may be your best shot.

What You'll Work On

  • Scale the infrastructure that lets AI agents operate reliably for millions of users

  • Build state-of-the-art agentic UX

  • Create observability, benchmarks, and evals for trillions of tokens

  • Ensure every token delivers maximum value at minimum cost

  • Build and maintain cutting-edge integrations with WhatsApp and iMessage

Tech Stack

TypeScript, Fastify, Drizzle, Postgres on Neon, Vercel AI SDK, AI Gateway, Vercel Workflow, GKE, SwiftUI iOS, Next.js

Every engineer gets a $200/month Codex subscription.

What We Look For

Exceptional engineer or founder - Previous wins or big losses. Both count.

Shipped agents to production at scale - Not prototypes. Real systems, real users.

Speed over process - You value iteration over perfection and don't wait for sign-off before pushing to prod.

No permission culture - Comfortable making decisions and shipping with minimal guidance.

True believer - You see personal AI as the most important thing you can work on right now. If you don't, this isn't for you.

The Team

A founder who previously sold a company to Farcaster, a founding engineer who was one of the earliest at a $500M-raised healthtech company, and a founding operations manager from one of the largest French banks.

Office in central Warsaw with a great view. Silicon Valley culture, Warsaw timezone.

Compensation

  • $100,000-$120,000 cash
