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. 💼 Our offer: - Flexible work setup — work remotely or from the office, we focus on results, not location; - Support for a comfortable work environment — we compensate coworking expenses and EcoFlow power stationsto help our team stay productive during power outages in Ukraine; - Unlimited vacation and sick leave, because we trust our people to manage their time responsibly; - Relocation support for team members who want to move; - Regular performance-based bonuses that reward individual and team impact; - Learning support — we cover 50% of professional courses and development programs; - Language & wellbeing support — we cover 50% of English classes and psychological consultations; - Career growth opportunities — we prioritize internal promotions and development; - Team culture that actually feels like one — regular gifts, company merch, and team events throughout the year; - Real impact — we are small enough for every voice to be heard and big enough to turn great ideas into action quickly.
