PERN Stack and Go Backend Engineer

Job Summary:

Reputation is seeking a Go Backend Engineer with PERN Stack experience to maintain and contribute to a large ecosystem of production microservices and web services running on GCP. In this role, you will keep services healthy, resolve issues, and deliver new features across a well-established distributed platform. While Go is the primary language, the platform also includes a PERN stack (PostgreSQL, Express, React, Node.js), and you will be expected to work comfortably across both. We are looking for engineers who can build simple, fast, and scalable software in a fast-paced environment.

Responsibilities:

• Maintain and enhance existing Go microservices across a distributed, event-driven platform.
• Contribute to Node.js /Express and GraphQL API services as needed.
• Support and maintain React (Class Components) frontend applications when required.
• Contribute to new feature development based on product and business requirements.
• Manage and update Helm charts for deployments across Stage, Production, and EU environments.
• Maintain and improve GitHub Actions CI/CD pipelines.
• Troubleshoot and resolve production incidents across services.
• Write and maintain unit, integration, and end-to-end tests (using Testify and testcontainers -go).
• Participate in code reviews and uphold code quality standards.
• Collaborate with DevOps and platform teams on infrastructure-related changes.

Qualifications:

• Bachelor's degree in Computer Science, Engineering, or related field (or equivalent practical experience).
• 2+ years of hands-on Go (Golang) development experience in a production environment, with exposure to Node.js/Express and React.
• Strong understanding of microservices architecture, distributed systems patterns, and experience working in a large microservices ecosystem (50+ services).
• Proficiency with Kubernetes and Helm writing and managing Helm charts for multi-environment deployments.
• Hands-on experience with GitHub Actions for CI/CD workflows including build, test, and deploy pipelines.
• Experience with GCP services, particularly Pub/Sub for event-driven messaging, and RabbitMQ (AMQP) for message queue management.
• Solid experience with PostgreSQL (including ORM usage via GORM/pgx) and Redis.
• Familiarity with Elasticsearch (indexing, querying, and percolation patterns).
• Experience with Docker and containerized application development.
• Familiarity with structured logging, health checks, Prometheus metrics instrumentation, and observability tools (OpenTelemetry).
• Experience with Node.js, Express.js, and GraphQL (schema design, resolvers, API integration).
• Familiarity with React (specifically Class Components) for maintaining existing frontend applications.
• Exposure to AWS Redshift or data warehouse integrations, multi-region cloud deployments (US + EU on GCP), and Terraform for infrastructure-as-code.
• Strong problem-solving skills, excellent written and verbal communication, and ability to work independently in a distributed team.
