Senior Backend Developer (Node.js)

We are building a high-performance, real-time slot gaming platform and are looking for a Senior Backend Developer who will take ownership of our entire backend direction.

🧩 What you’ll do

• Own and drive the backend direction of the company as one of the key technical leaders;
• Design and implement new game mechanics on top of our existing PGS, extend its capabilities, and contribute to core gameplay engine development;
• Architect scalable, secure, and high-performance backend services using Node.js and TypeScript;
• Work closely with Game Logic, Frontend, and DevOps teams to ensure seamless integrations, real-time performance, and platform-wide consistency;
• Define backend engineering standards and enforce best practices across code quality, architecture, and performance;
• Design and maintain backend infrastructure: schemas, caching, messaging flows, microservices, gateways;
• Participate in roadmap planning, technical decision-making, and architectural discussions as the platform evolves;
• Support a rapidly growing product and engineering environment — we are scaling fast, and you will play a major role in that growth.

🧠 What you bring

• 5+ years of backend development experience, including ownership of complex systems or features;
• Strong expertise with Node.js + TypeScript and modern frameworks (Fastify, Nest.js);
• Advanced knowledge of SQL and NoSQL databases: PostgreSQL, MongoDB, Redis;
• Solid experience with message brokers (RabbitMQ or Kafka) and queue-based, event-driven design patterns;
• Deep understanding of distributed systems, microservices, and real-time communication (WebSocket, Socket.io);
• Experience building high-performance APIs, async flows, caching strategies, and scalable architectures;

• Confident with CI/CD, Git, automated testing (Jest), and monitoring/observability tools (Grafana, Loki, Tempo).

   

💎 Nice to have

• Knowledge of PHP/Laravel or experience with other backend ecosystems;
• Familiarity with AWS, Docker, Kubernetes, containerized deployments;
• Experience with RNG, platform integrations, or the iGaming ecosystem.
