Full Job Description

📋 Description

• We're looking for a Native PHP Developer with 5 to 10 years of experience building and maintaining high-throughput, production-grade backend systems.
• You should have strong command of core (vanilla) PHP, not just framework-driven development, and direct experience with transaction-heavy, mission-critical applications.
• Experience in payments, billing, telecom, or any high-availability transactional environment is a strong plus.
• Autonomy, rigor, and problem-solving are essential, as is comfort working independently in a distributed, cross-timezone team.
• Design, develop and maintain robust backend services in native PHP (7/8), with clean, testable and well-documented code.
• Build and optimize high-volume transaction and billing workflows, ensuring reliability, idempotency and data integrity at scale.
• Develop and maintain REST/SOAP APIs for operator, merchant and third-party integrations.
• Work with relational databases (MySQL/MariaDB/PostgreSQL): schema design, query optimization, indexing and performance tuning.
• Integrate with external systems and gateways (payment, messaging/SMS, USSD, carrier connections, monitoring, billing).
• Implement asynchronous processing using message queues (RabbitMQ, Kafka) and caching layers (Redis/Memcached).
• Ensure application security, resilience and observability (logging, metrics, alerting) in a high-availability context.
• Contribute to CI/CD pipelines, code reviews, and Git-based workflows.
• Collaborate with product, ops and QA teams to ship, monitor and continuously improve services in production.

🎯 Requirements

• Expert-level native/core PHP (7/8), solid OOP, design patterns, and clean architecture.
• Proven experience with high-throughput, transactional backend systems (mandatory).
• Strong SQL skills (MySQL/MariaDB/PostgreSQL): modeling, optimization, debugging.
• Solid experience designing and consuming REST/SOAP APIs.
• Comfort with Linux environments, Git and CI/CD workflows.
• Familiarity with message queues (RabbitMQ/Kafka), caching (Redis), and asynchronous processing.
• Good understanding of application security and data integrity in sensitive/financial contexts.
• Fluent English and the ability to work autonomously across timezones.

🏖️ Benefits

• Opportunity to work on platforms that process transactions at real scale.
• Dynamic and fast-paced environment that values autonomy, ownership and technical excellence.
• Ability to contribute directly to revenue-critical systems used worldwide.
• Fair, transparent, and inclusive recruitment process.
• Commitment to maintaining the confidentiality and security of your information throughout the recruitment process.
