Senior Golang Backend Engineer Needed for Microservices, Kubernetes & High-Performance Systems

We are seeking a highly experienced Senior Golang Backend Engineer to design, build, and optimize scalable, high-performance microservices architectures. The ideal candidate will have deep expertise in Go, containerization, orchestration, cloud infrastructure, and event-driven systems. You will play a key role in delivering production-grade backends that handle high traffic with low latency, strong reliability, and clean maintainability. This is an opportunity to work on complex backend systems where performance, scalability, and long-term architectural quality matter. We value engineers who think like owners and deliver battle-tested solutions. Key Responsibilities - Architect and develop high-performance RESTful APIs and gRPC services in Golang (using Gin or Echo frameworks) capable of handling 10k+ RPS with sub-50ms latency. - Design and implement event-driven architectures using Apache Kafka and RabbitMQ for reliable, real-time messaging and decoupled workflows. - Build and maintain Dockerized microservices orchestrated with Kubernetes on Amazon Web Services (AWS), including EKS/ECS, with focus on auto-scaling, zero-downtime deployments, and cost optimization. - Implement Infrastructure as Code with Terraform and establish robust CI/CD pipelines (GitHub Actions or similar) for automated testing and deployments. - Develop WebSocket solutions and real-time capabilities where needed. - Write clean, well-tested code with high coverage (unit, integration, and performance tests). Requirements - 7+ years of professional experience building production Golang backends and microservices. - Strong hands-on expertise with Docker, Kubernetes (including production deployments and scaling), and AWS services. - Proven experience designing and optimizing systems with PostgreSQL and Redis at scale. - Solid background in event-driven systems using Apache Kafka and/or RabbitMQ. - Proficiency with Terraform, Git/GitHub, and modern DevOps practices (CI/CD, monitoring, Infrastructure as Code). - Demonstrated ability to build high-concurrency, high-throughput systems (experience with flash sales, real-time platforms, or high-traffic SaaS is a strong plus). - Experience with performance optimization, observability, and writing maintainable, well-documented code. - Strong understanding of secure backend development practices (authentication, data protection, PCI compliance experience is advantageous). - Excellent communication skills and ability to work independently while collaborating with product and engineering teams. Nice-to-Have - Experience with gRPC in production. - Background in fintech, e-commerce, SaaS platforms, or high-scale data pipelines. - Familiarity with service mesh patterns or API gateways. - Previous work on real-time event platforms or distributed task queues. What We Offer - Long-term collaboration with a focus on quality and sustainable architecture. - Opportunity to work on technically challenging problems with real business impact. - Clear requirements, regular communication, and respect for your expertise. - Flexible remote work with consistent project pipeline for the right candidate. If you are a senior Go engineer who takes pride in building reliable, high-performance distributed systems and wants to partner with a team that values clean code and thoughtful architecture, we would love to hear from you. Please include in your proposal: - A short overview of your most relevant Go microservices project (with metrics if possible). - Your experience with Kubernetes + AWS and PostgreSQL/Redis optimization. - Your availability and preferred engagement model (hourly or milestone-based). We look forward to reviewing your application.
