We are looking for a Backend Developer to work on integrating and developing payment solutions within an iGaming product.

Responsibilities:

• Integrate and maintain payment providers.

• Develop and evolve a unified integration layer (payment gateway/adapter layer): API standardization, configuration, parameters, status mapping, error handling.

• Implement callback/webhook processing: signature validation, idempotency, retries, deduplication, race condition handling.

• Build reliable financial processes: transaction handling, consistency, auditability, correct payment state management (state machine), and secure payouts.

• Work on reconciliation: matching payments with providers, investigating discrepancies, automating reporting and logging.

• Design a scalable payment module architecture focused on long-term maintainability and fast integration of new PSPs.

Requirements:

• PHP 8.x, 3+ years of experience.

• Laravel 1+ year (or equivalent Symfony experience).

• MySQL 5.7–8.0: transactions, high-load systems, locking/isolation levels, query optimization.

• Redis (cache, sessions/locks, rate limiting).

• Git/GitHub, GitHub flow.

• Strong API experience: integrating third-party REST/JSON APIs, building APIs, logging, versioning, documentation.

• Experience with payment system integrations.

• Understanding of common payment system challenges: idempotency, retries, timeouts, webhook delivery, payment status handling, chargebacks/rollback logic (system-level), anti-fraud patterns.

Nice to have:

• Docker, Nginx, basic DevOps skills (Debian-based systems).

• NodeJS / Socket.io or event-driven communication between services (Pub/Sub), Redis Pub/Sub between PHP and NodeJS/Swoole.

• Queues (Horizon/Redis queues, RabbitMQ).

• Frontend experience (Vue 3 / Nuxt 3) as a plus for better flow understanding.

What we offer:

• Remote work and flexible schedule

• Competitive salary, regular performance reviews, and initiative-based bonuses

• Fast hiring process — only 2–3 stages and you’re in

• 24 paid vacation days + 10 sick days per year

• Strong team that actively shares knowledge and expertise

• We don’t hire team leads — we grow them internally

• Budget and resources to bring your ideas to life

• Transparent processes with minimal bureaucracy

• A strong community: we play, attend conferences, network, and genuinely enjoy working together
