Description

We are looking for a Senior Node.js Developer with strong hands-on experience building, scaling, and maintaining production backend systems.

Experience with Docker and containerized deployments
Knowledge of monitoring, logging, and observability practices
Understanding of distributed systems concepts
Ability to explain Node.js internals, including the Event Loop, Worker Threads, and Child Processes
Experience handling race conditions, duplicate requests, and idempotency
Strong debugging and root cause analysis skills

Responsibilities

Design, develop, and maintain scalable backend services using Node.js
Build and optimize APIs capable of handling high traffic volumes
Investigate and resolve production performance issues
Contribute to architectural decisions and technical planning
Ensure backend systems are reliable, observable, and maintainable
Collaborate with teams to improve system performance and scalability
Mentor junior developers and support technical growth within the team
Implement preventive measures after production incidents

Nice to have

Experience designing systems handling millions of API requests per day
Experience with microservice architectures and monolithic-to-microservice trade-offs
Strong background in production incident management
Previous experience in technical leadership or mentoring roles
Experience working with high-availability or distributed systems

Working conditions

Senior-level backend development role
Focus on production-grade Node.js systems
Opportunity to contribute to architecture and technical decisions
