Role Overview We’re growing the payment microservice of a fintech/iGaming platform, built on Laravel 10 / PHP 8.1, handling deposits, withdrawals, and currency management. The service integrates with 70+ payment providers and runs in a multi-brand, multi-currency, high-load environment. It’s part of a distributed platform of independent microservices communicating through dedicated SDKs. We’re looking for a backend developer to strengthen the team: onboarding new providers, evolving the core payment-processing engine, and maintaining the reliability of a business-critical service where mistakes cost real money.

⚙️ Your Tasks — Onboarding and maintaining payment provider integrations (billing-class pattern + aggregator layer); — Developing and supporting deposit, withdrawal, and currency-management functionality; — Evolving the core payment-processing engine and multi-brand payment-system configuration; — Designing database schemas and optimizing query performance; — Writing clean, testable code with unit and feature test coverage (PHPUnit / Laravel Test); — Following code style (Laravel Pint) and passing static analysis (PHPStan); — Participating in code reviews, diagnosing and resolving production incidents; — Collaborating with adjacent services through SDKs (bank, users, bonus, notifications).

Our Offer — Flexible work setup — work remotely or from the office, we focus on results, not location; — Support for a comfortable work environment — we compensate coworking expenses and EcoFlow power stations to help our team stay productive during power outages in Ukraine; — Unlimited vacation and sick leave, because we trust our people to manage their time responsibly; — Relocation support for team members who want to move; — Regular performance-based bonuses that reward individual and team impact; — Learning support — we cover 50% of professional courses and development programs; — Language & wellbeing support — we cover 50% of English classes and psychological consultations; — Career growth opportunities — we prioritize internal promotions and development; — Team culture that actually feels like one — regular gifts, company merch, and team events throughout the year; — Real impact — we are small enough for every voice to be heard and big enough to turn great ideas into action quickly.
