Build products,
not tickets
Most "senior" roles mean maintaining someone else's legacy codebase. Here, you build real products — Cortex AI Platform, Cortex IDP — for clients like Procter & Gamble, IQVIA, and BFF Banking Group. Small team. No bureaucracy. Twenty years of staying in business by writing good software.
The kind of place senior engineers stay
ITSG is 40-something engineers building software for international clients — Procter & Gamble, Juice Technology, BFF Banking Group. The projects are real, the deadlines are real, and the code goes to production. No one's writing specs that sit in a drawer.
The CTO still writes code. Architecture decisions happen in conversations, not committees. You pick your tools, manage your time, and own your deliverables. If that sounds like how you already prefer to work — you'll fit right in.
- Own products: Cortex AI Platform and Cortex IDP
- Long-term contract engagements
- Remote-first, Warsaw office when you want it
- 20 years in business, 500+ projects shipped
