- Actively contribute to technical design, system architecture, and integration strategies, collaborating with **cross-functional teams;
- Manage the full development cycle from analyzing complex business requirements to production deployment and maintenance, ensuring **end-to-end technical solutions;
- Implement and enforce clean, maintainable, and well-documented code following best practices (** DDD, Clean Architecture, Design Patterns**) and established coding standards;
- Participate actively in code reviews, providing constructive feedback and upholding code quality across all services;
- Proactively identify and resolve performance bottlenecks, architectural deficiencies (e.g., event loopholes), and **technical debt;
- Contribute to the continuous improvement of CI/CD pipelines, automated testing (unit, integration, e2e), development processes, and observability (** Grafana, OpenTelemetry**).
**👤 Our criteria:
- 5+ years of professional experience in backend development, with significant experience in a senior or lead role within high-load, distributed systems;
• Expert-level proficiency with the Laravel framework and experience with Symfony (would be a plus);
• Mandatory hands-on experience with Apache Kafka for building and consuming event streams;
• Extensive experience with Redis for caching, session management, and performance optimization;
• Strong understanding and practical experience with RabbitMQ (or other message brokers) for asynchronous task processing;
• Proven experience in the iGaming domain or other high-traffic, real-time transaction processing environments;
• Proficiency in database design and optimization (e.g., PostgreSQL, MySQL, Clickhouse, MongoDB);
• Solid understanding of microservice architectures, RESTful API design, and modern architectural patterns ( DDD, Clean Architecture**);
• Experience with Docker and Kubernetes (K8s) for containerization and orchestration;
• Proficiency with Gitlab CI/CD (or similar CI/CD platforms) for automated deployments;
• Experience with monitoring and logging tools (e.g., Grafana, OpenTelemetry, ELK Stack);
• Strong problem-solving, analytical, and critical thinking skills.
