🎯 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.
👤 Our Criteria
- 5+ years of commercial PHP experience, confident with PHP 8.1+;
- Strong Laravel knowledge (Eloquent, queues, events/listeners, service container, facades, middleware);
- Solid MySQL: schema design, query optimization, indexing, partitioning, master/slave (read/write) splitting;
- Designing and integrating REST APIs, working with third-party HTTP APIs (Guzzle), handling callbacks and webhooks;
- Understanding of precise monetary arithmetic (bcmath; no floats in financial calculations);
- Experience with message queues (RabbitMQ / AMQP) for asynchronous processing;
- Docker and working in a containerized environment;
- Git, teamwork with feature branches and code review;
- Familiarity with design patterns (Strategy, Factory, Facade) and SOLID principles;
- English sufficient to read technical documentation.
