Project: Long-term
About the role
We’re looking for a Senior Golang Backend Developer to build and scale microservices-based systems and help the engineering team migrate existing backend services from Node.js/NestJS to Go.
The role involves designing high-load services, working with distributed systems, improving backend architecture, and implementing modern patterns for asynchronous processing and real-time communication.
You’ll work with an existing production codebase, contribute to the migration strategy, and help the team gradually transition services from Node.js to a scalable Go-based architecture.

4+ years of backend development experience
3+ years of hands-on experience with Go / Golang
Strong understanding of Go fundamentals, concurrency, goroutines, channels, interfaces, contexts, and error handling
Strong experience with PostgreSQL, MongoDB, and Redis
Solid understanding of microservices architecture
Experience building high-load and distributed systems
Experience with asynchronous processing, queues, and event-driven architectures
Experience building REST APIs, WebSockets (WS/WSS), and RPC/gRPC services
Ability to design scalable, maintainable, and reliable backend services
Ability to read, understand, refactor, and migrate existing codebases
Strong understanding of performance optimization and observability
High attention to detail

Refactor and gradually replace existing Node.js services while maintaining system stability
Design APIs and service-to-service communication using REST, WebSockets, RPC/gRPC, and event-driven patterns
Work with asynchronous architectures, queues, and distributed systems
Optimize backend performance, reliability, and scalability
Improve architecture and engineering practices during the migration
Review code and contribute to technical decisions
Collaborate with developers and other cross-functional team members
