GoLang Specialist

Location: Moratuwa, Sri Lanka

We are looking for a great Go lead developer who possesses a strong understanding of how best to leverage and exploit the language’s unique paradigms, idioms, and syntax. Your primary focus will be on developing Go packages and programs that are scalable and maintainable. You will ensure that these Go packages and programs are well documented and have reasonable test coverage. You will coordinate with the rest of the team working on different layers of the infrastructure. A commitment to collaborative problem solving, sophisticated design, and quality product is essential.


  • Go Programming: Proficiency in the Go programming language is essential. You should have a strong understanding of Go’s syntax, data structures, concurrency mechanisms (goroutines, channels), and how to write efficient and maintainable code.
  • API Design and Integration: Familiarity with designing and implementing RESTful APIs and working with different API authentication methods (OAuth, JWT, API keys) is crucial. You should also be comfortable with integrating APIs from various providers and services.
  • Concurrency and Parallelism: Go’s concurrency model is a core feature. You should be skilled in designing and implementing concurrent and parallel systems to handle large-scale integrations efficiently.
  • Error Handling: Proficiency in handling errors and exceptions gracefully is vital. Go’s error handling strategy with explicit error returns is a fundamental aspect of writing reliable code.
  • Data Serialization: Experience with data serialization formats like JSON and XML, and Go’s standard encoding/json package, is important for data exchange between systems.
  • Message Queues and Pub/Sub Systems: Knowledge of message queuing systems (e.g., RabbitMQ, Apache Kafka) and publish-subscribe architectures can be valuable for handling asynchronous communication in integrations.
  • Database Interaction: Familiarity with working with databases, both SQL and NoSQL, is essential as data storage and retrieval often play a significant role in integrations.
  • Web Frameworks: Understanding of Go web frameworks like Gin, Echo, or Fiber can expedite the development of RESTful APIs.
  • Authentication and Authorization: Mastery of authentication and authorization mechanisms, including OAuth2, OpenID Connect, and role-based access control (RBAC), is vital for securing integrations.
  • Testing: Proficiency in writing unit tests, integration tests, and end-to-end tests is necessary to ensure the reliability of your integrations.
  • Containerization and Orchestration: Familiarity with containerization technologies (Docker) and container orchestration platforms (Kubernetes) is beneficial for deploying and scaling integrations.
  • Version Control: Proficiency in using version control systems like Git for managing codebase changes and collaboration.
  • Security Best Practices: Understanding of security best practices, including data encryption, input validation, and protection against common vulnerabilities (e.g., SQL injection, XSS), is crucial to secure integrations.
  • Enterprise Integration Patterns: Knowledge of common integration patterns like point-to-point, publish-subscribe, request-reply, and event-driven architecture can be advantageous.
  • Scalability and Performance Optimization: Skills in optimizing integrations for high scalability and performance, including load balancing, caching, and distributed systems principles.
