Lead Full-Stack Engineer (Node.js & Vue)

About the role

We are looking for a Lead Full-Stack Engineer to drive the design and delivery of our new restaurant-focused services. You will work on a high-scale Point-of-Sale platform serving thousands of stores across the US, now expanding into the restaurant market.

Key responsibilities

• Design and implement end-to-end restaurant services, from data model and APIs to the merchant-facing screens.
• Extend and harden existing production services while maintaining stability.
• Ensure data correctness under concurrency, including transactional integrity, idempotency and graceful handling of network outages.
• Build offline-capable clients, state sync, and reconciliation logic.
• Implement queueing, background jobs and event-driven flows using technologies such as Kafka, RabbitMQ or SQS.
• Plan and execute safe roll-outs that affect tens of thousands of users.
• Collaborate with product managers and designers to shape features, not just implement specifications.
• Provide technical direction, conduct code reviews and mentor other engineers.

Required profile

• 8+ years of full-stack development experience, with recent senior-level responsibility.
• Deep expertise in Node.js and TypeScript across both backend and frontend.
• Strong knowledge of REST API design, micro-services architecture and relational databases (PostgreSQL or MySQL).
• Hands-on experience with non-relational stores such as Redis or MongoDB.
• Proven work with message queues and streaming platforms (Kafka, RabbitMQ, Kinesis, SQS, BullMQ).
• Front-end proficiency with Vue (React or Angular acceptable) and modern SPA patterns.
• Experience building real-time interfaces using websockets (socket.io preferred).
• Excellent debugging skills and ability to resolve production incidents quickly.
