Junior+ Java Developer (Backend / Integrations) / IGaming

We build a payment-orchestration platform (PSP hub) that connects merchants to dozens of payment providers. You'll join one of two small backend teams (5 developers each — seniors, a Tech Lead, and an Architect) building and maintaining integration services that process real financial transactions in production.

You'll work alongside experienced engineers and strong QA, but we’re looking for someone who can already work independently on well-defined Java backend tasks and take ownership of their code from implementation through testing and review.
