• Enhance asynchronous operations through Kafka, supporting scalable, real-time event handling
• Optimize PostgreSQL interactions using the Sequelize ORM for performance and reliability
• Ensure robust security standards across all payment processing workflows
• Contribute to our containerized infrastructure using Kubernetes and manage deployments with Kapitan

Requirements

• 5+ years of professional software development experience
• Strong expertise in TypeScript and Node.js with modern ES features
• Solid experience with microservice architecture and event-driven systems (Kafka)
• Proficiency in RESTful API design and implementation
• In-depth knowledge of PostgreSQL and ORM frameworks like Sequelize
• Hands-on experience with Docker, Kubernetes, and container orchestration
• Understanding of payment processing systems, security requirements, and gateway integrations (e.g. Adyen) is a plus
• Familiarity with POS/PMS systems and integration patterns (e.g. Oracle Simphony, Vectron, Mews) is a plus
• Comfort with asynchronous programming and WebSocket implementations
• Experience with dependency injection frameworks (e.g. tsyringe)
• Strong testing practices, including unit, integration, and E2E testing
• Understanding of API security, rate limiting, and observability tools

Benefits

• Work on a modern, technically challenging platform used by millions
• Contribute to architecture decisions and technical direction
• Collaborative, engineering-focused culture
• Opportunity to grow into tech leadership roles
• Competitive compensation package and attractive benefits (e.g. lunch vouchers, birthday gift, Urban Sports discount, etc.)

If you’re passionate about building scalable backend systems and want to make a meaningful impact on the hospitality industry, we’d love to hear from you.
