Backend Engineer

Parallax Gaming is pleased to announce an opening for the position of Backend Engineer, Platform Integrations.

Location: Tbilisi, Georgia
Employment type: Full-time
Work format: On-site, five days a week. Remote and hybrid work are not available.

About the Role:

Parallax Gaming is a game provider. We develop real-money games on our own game engine and operate them for our partners.

We are looking for a Backend Engineer whose initial focus will be integrations between our games and our partners: wallet and game launch APIs, transaction processing, and backend services supporting tools used by support, finance, and compliance teams. The engineering team works across the whole engine, and this role is expected to do the same over time.

We value disciplined engineering: delivering small, reviewable changes, validating behavior through meaningful tests, and improving existing code through focused refactoring. You own every change you submit and can explain how it works and how you validated it.

Our core backend stack is Java, Spring Boot, and PostgreSQL.

Responsibilities:

** Develop and maintain integrations with partners` wallet and game launch APIs;
** Ensure reliable and correct wallet transaction processing, including reconciliation and recovery from failures;
** Support partner integrations from sandbox testing through production launch;
** Build and maintain backend APIs and internal tools used by support, finance, and compliance teams;
** Write and maintain automated tests alongside implementation;
** Investigate production issues and maintain integration documentation and incident notes;
** Contribute to other areas of the engine as needed.

Requirements:

** Professional Java and Spring experience building and maintaining production backend services;
** Experience building and supporting API integrations in production;
** Strong SQL and practical PostgreSQL experience;
** Ability to deliver small, reviewable changes supported by meaningful automated tests;
** Experience refactoring existing code safely, with tests preserving behavior;
** Ability to investigate integration problems using documentation, application behavior, logs, and data.

Nice to Have:

** Experience in payments, fintech, or online gaming, particularly wallet integrations, reconciliation, or regulatory certification;
** Familiarity with CQRS and event-driven architecture;
** Experience with production monitoring, containerized applications, and continuous delivery.

What We Offer:

** A say in technical design decisions for integrations and, over time, other areas of the engine;
** Ownership of an area of a production system that handles real money, with responsibility from implementation through deployment;
** A documented codebase where refactoring is part of normal work;
** A current stack, a small team, and direct contact with the partners you integrate with;
** Involvement in partner launches and regulatory certification.

Interview Process:

A conversation about your previous work, followed by a working session on a problem from our codebase. No take-home assignment.

Compensation: The final offer will depend on experience and skills.
