Hello, we are luca.
We’re on a mission to reimagine hospitality with a smart, seamless guest experience platform. From booking to check-in, ordering to payment – luca makes it all digital, effortless, and completely app-free.
We simplify the complex so that hotels, restaurants, and events can focus on what truly counts: happy guests, empowered teams, and unforgettable experiences.
Build what matters. Scale what works.
luca is looking for a Senior Backend Engineer (m/f/d) to join the Platform Team and help shape the backbone of a product used by millions. You’ll work on mission-critical systems like payment processing, hotel integrations, and gastronomy solutions — and play a key role in building MVPs, scaling services, and driving architectural decisions. Expect a modern tech stack, real ownership, and a collaborative engineering culture where your voice matters.
Tasks
🎯 Your Mission
* Build scalable microservices: Design, develop, and maintain Node.js microservices written in TypeScript within a modern, event-driven architecture.
* Power seamless payments: Extend and enhance our payment integrations with leading POS systems like Oracle Simphony, Vectron, Gastrofix, and Mews.
* Drive real-time performance: Leverage Apache Kafka to optimize asynchronous workflows and ensure high-throughput, real-time event handling.
* Optimize data access: Fine-tune PostgreSQL queries using Sequelize ORM to boost reliability and performance across critical services.
* Champion security: Implement and maintain robust security practices for all payment-related workflows and data handling.
* Scale with confidence: Contribute to our containerized infrastructure with Kubernetes, managing deployments via Kapitan for streamlined delivery and observability.
Requirements
🔍 What You Bring to the Table
* 5+ years of professional backend development experience, with deep expertise in TypeScript and Node.js
* Proven track record designing and scaling microservice and event-driven architectures (Kafka, etc.)
* Strong command of PostgreSQL and ORMs like Sequelize, with a performance-first mindset
* Experience building clean, maintainable RESTful APIs and working with asynchronous systems (WebSockets, queues)
* Comfortable navigating Docker, Kubernetes, and modern DevOps environments
* Solid testing discipline across unit, integration, and E2E layers
* Familiarity with dependency injection frameworks (e.g. tsyringe) and observability tools
* Bonus points for knowledge of payment gateways (e.g. Adyen), POS/PMS systems (e.g. Oracle Simphony, Vectron, Mews), and security best practices
