• Designing and scaling backend services using Node.js & TypeScript
• Owning system and service architecture across multiple domains
• Building high-throughput REST and asynchronous APIs
• Designing and evolving event-driven systems
• Improving performance, reliability, scalability, and observability
• Debugging and resolving complex production issues
• Reviewing code and mentoring engineers
• Working closely with product and platform teams on technical strategy

• Expert-level TypeScript & Node.js experience
• Strong experience with backend frameworks (Fastify, Express, NestJS)
• Deep knowledge of distributed systems and async patterns
• Strong PostgreSQL and relational database design skills
• Experience with cloud platforms (AWS, GCP or Azure)
• CI/CD, Docker and production deployment experience
• Strong testing practices and Git workflows
• 6+ years of backend engineering experience

• Kafka, RabbitMQ, SQS or similar messaging platforms
