Health and sports benefits tailored to your needs.

Scope of the role:
Building a new licensing model in C++ - developing a solution created from scratch, responsible for checking user entitlement to particular product features, working with large data sets (fetching, comparing, accepting or rejecting)
Integrating the solution with existing tools - interface-based integration into desktop, web, server and batch applications; some of them are Java-based, so work at the seam between the technologies is done in Java

What you need to join us:
Must have:
Strong C++ knowledge - the foundation of the role, around 80% of the work
At least basic, hands-on Java experience (e.g. a year or two in a project where Java was used) - expert level is not expected
English at C1+ level - fluent day-to-day communication in an international, distributed team
Openness to working with other technologies (Java, JavaScript, Python), work in Polish business hours
A team-oriented attitude - solving problems together, sharing ideas, staying in touch with the team rather than working in isolation
Ability to work from the territory of Poland (citizenship, residence card, visa, etc.)
Nice to have:
JavaScript
Python - used among others in tests and scripts
REST API
Knowledge of OAuth2, OpenID, IdP
