Senior PHP Developer (Core)

🎯 Role Overview:

We’re looking for a Senior PHP Backend Developer to strengthen the engineering team of a high-load iGaming platform, built on PHP (Laravel and Symfony).
You’ll work on backend services, APIs, and event-driven integrations using Kafka, RabbitMQ, and Redis, ensuring reliable asynchronous processing across a distributed system.
The role involves designing scalable solutions, improving existing architecture, refactoring legacy code, and maintaining system performance and stability.
We’re looking for an engineer who can take end-to-end ownership of features, make independent technical decisions, and contribute to code quality, architectural improvements, and team knowledge sharing.

⚙️ Your Tasks:

• Design, develop, and maintain backend services and APIs of varying complexity using PHP (Laravel and Symfony).
• Develop and support event-driven integrations based on Kafka and RabbitMQ (producers/consumers, queues, message processing).
• Understand how asynchronous processing works: message flow, delivery guarantees, idempotency, retries, ordering, backpressure, and failure handling.
• Design and optimize data handling: relational databases and caching/storage with Redis.
• Apply design patterns and solid architectural principles (SOLID, DDD elements, layered and event-driven architecture) when building and reviewing code.
• Refactor existing code: improve structure and readability, reduce coupling, and pay down technical debt without breaking behavior.
• Analyze requirements and proactively highlight technical risks and constraints to the team before development starts.
• Make architectural decisions with scalability, reliability, and performance of a distributed system in mind.
• Perform code reviews and maintain code quality standards and best practices within the team.
• Investigate and resolve defects and incidents using logs, databases, metrics, and monitoring.
• Build and maintain technical documentation and improve development processes within the team.
• Mentor colleagues and share expertise within the engineering community.
• Jump into tasks of adjacent teams when needed.

👤 Our criteria:

• Successfully onboard into the team’s development processes, PHP codebase (Laravel and Symfony), and infrastructure (Kafka, RabbitMQ, Redis).
• Demonstrate ownership of assigned features from requirements analysis through production release and support.
• Confidently develop and maintain asynchronous integrations via Kafka/RabbitMQ with minimal supervision, with a clear understanding of how async processing behaves under load and failures.
• Apply suitable design patterns and architectural approaches, and keep code clean through regular refactoring.
• Deliver consistent, high-quality development and delivery.
• Effectively collaborate with other developers, QA, product managers, and other stakeholders.
• Contribute to improvements in architecture, development processes, or team knowledge sharing.
• Show the ability to independently break down tasks, make sound technical decisions, and see them through to completion.
