Back-end Software Engineer (Java)

To develop an identity management system for some of the biggest Polish telecommunication companies.

The functionalities we’ve created include federated authentication and authorization system, user authentication and authorization, easy onboarding for mobile (TMForum) federation between applications for microservice platforms, anomaly paternity detection, seamless authentication, two-factor authentication and enhancement to n-factorA scenarios, device whitelists, backchannel authentication, biometric verifications and sensitive data protection – through consent and permission management.

The solutions we prepared were based on microservice architecture using containerization, which allowed us to achieve high scalability and responsiveness (max 10ms). The created multi-level system ensures full customization and is easily multilevel auditable. We plan to use our accumulated experiences on future identity management implementations for additional outland telecommunications operators.

We focus on autonomy and, do not force methods or strategies. We trust your instinct – you decide how best to advance the project and you are responsible for each stage of the Software Development Life Cycle.:

Our team is responsible for most of the project work – from analysis and design, through the implementation of new solutions, migration between versions, testing, training, maintenance, and post-implementation assistance.

We work as a team and we expect the same from you – group brainstorming, quick code review, rubber duck debugging or a short pair programming session are tools that are regularly used by every member of our team.
