The Role We are looking for a Senior Golang Developer (Fullstack, Backend-Heavy) to join one of our high-growth client teams as a core software architect.

In this role, you will be responsible for designing and scaling high-performance, low-latency microservices using Go, while also stepping into the frontend layer to build clean, responsive user interfaces.

You will be the engineering driver behind the client’s product scaling efforts, moving beyond basic CRUD applications to solve complex data ingestion, distributed systems concurrency, and real-time state challenges.

This is a role for a systems-thinking developer who loves the speed and simplicity of Go but understands how to deliver a complete, polished end-to-end user experience.

What we are looking for: 5+ years of software engineering experience, with strong, production-grade mastery of Go (Golang), its memory model, channels, and idiomatic concurrency patterns. Proven track record of building microservices using HTTP frameworks (Gin, Echo, Chi) or gRPC / Protocol Buffers.

Solid experience with modern frontend development using TypeScript and React. js or Vue. js for consuming complex API contracts. Advanced knowledge of relational databases (PostgreSQL preferred) along with high-performance query optimization and connection pooling.

Experience managing message brokers or event streaming platforms like Kafka, RabbitMQ, or Redis. Hands-on experience containerizing services with Docker and orchestrating deployments via Kubernetes inside cloud environments (AWS, Azure, or GCP).

A strict testing mindset, implementing robust unit testing patterns (go test, test suites) and automated integration tests. Located in CET timezone (+/- 3 hours), we are unable to consider applications from candidates in other time zones. Nice-to-have: Experience with Infrastructure as Code (Terraform or Bicep).

Understanding of eBPF, WebAssembly (Wasm), or writing low-level networking tools in Go. Familiarity with frontend build tools like Vite or Webpack. Background in domain-driven design (DDD) and clean architecture.

Responsibilities

Design, implement, and maintain highly performant Go backends along with their corresponding frontend interfaces. Profile and tune Go applications (using pprof, flame graphs) to ensure minimal memory footprints and ultra-low latency.

Design structured, self-documenting RESTful or gRPC APIs that allow seamless communication between microservices and the client interface. Conduct constructive peer code reviews, championing clean code principles, SOLID patterns, and idiomatic Go architectures.

Work alongside DevOps engineers to build and maintain automated testing and deployment pipelines. What we offer: Get paid, not played No more unreliable clients. Enjoy on-time monthly payments with flexible withdrawal options.

Predictable project hours Enjoy a harmonious work-life balance with consistent 8-hour working days with clients. Flex days, so you can recharge Enjoy up to 24 flex days off per year without losing pay, for full-time positions found through Proxify.
