Full time

Platform Security Engineer (Senior+)

Posted by Complexio • Warsaw, Masovian Voivodeship, Poland

📍 Warsaw, Masovian Voivodeship 🕒 June 21, 2026

About the Role

We are looking for two Platform Security Engineers (Senior+) to join our Product Security domain. This role exists because the scope and importance of our work has outgrown the capacity of a single person.

Our platform underpins multiple products and handles sensitive, high-value data. At its core sits a large, graph-based data store that powers downstream systems. Building and securing access to that data, correctly and pragmatically, is critical to the company.

This is a hands-on engineering role. You will design, build, and ship production-grade security and privacy controls, not just define policies or review designs from the sidelines.
