Founding Design Engineer

This is a role that TechTree is recruiting for on behalf of one of our clients. TechTree is an AI-driven recruitment platform working with high-growth companies.

When you apply, our AI Agent matches you not just to this role , but to other relevant opportunities across our network, so one application can unlock multiple roles. Founding Design Engineer — shape how Boski looks, feels, and works, then build it yourself. On-site, Warsaw. Boski is an AI agent that wants you to win: it gets all the mundane stuff done — groceries, doctor appointments, even finding you a new job — so you can live your best life. By 2027, everyone will have a personal AGI working for them, and Boski is building it. Founded by a repeat founder who sold his last company to Farcaster, the team is now building out its founding group in Warsaw.

You'll own the product experience end to end — from the first prototype to the details people use every day — across web (TypeScript, React, Next.js) and iOS (SwiftUI).

What You'll Do → Own how Boski looks, feels, and works across web and iOS

→ Prototype interactions in code, test them with users, and ship improvements quickly

→ Take features from early sketches through production, including the engineering to make them work

→ Build reusable components and evolve the design system as the product grows

What We're Looking For → Exceptional product taste and engineering ability, with shipped products that prove both

→ Deep care about typography, motion, and interaction details, with a bias for speed over process

$100k–$120k cash, 2% equity, paid lunches, and a gym pass two minutes from the office.
