Job description

We're looking for a Senior Go (Golang) Engineer to become part of a high-performing ecosystem centered on integration and channels. The team operates under centralized governance that mitigates risks and orchestrates delivery, ensuring optimal technology choices and best practices are applied while supporting critical capabilities like automated processing, backend services, agent chat, and back-office interfaces. This position helps drive smooth operational workflows and next-generation engagement across the platform.

Responsibilities

• Write production-grade Go code with a focus on concurrent programming and performance optimization
• Design and build low-latency APIs to ingest, stream, and parse multi-format files without heavy RAM overhead
• Develop robust connectors to external systems and process dynamic incoming webhooks
• Implement transactional messaging and queuing solutions to guarantee order delivery
• Manage database connections to ensure data resiliency and consistency
• Maintain clean, well-tested code with comprehensive unit testing and mock frameworks
• Apply graceful error handling strategies to address pipeline failures
• Collaborate with the Solution Architect to align on technology selection and best practices
• Support critical backend services, automated processing, and back-office interfaces

Requirements

• 3+ years of hands-on experience writing production-grade Go, with expertise in concurrent programming (Goroutines, Channels, Context management) and performance optimization
• Experience building low-latency APIs (REST/gRPC) using frameworks such as Gin, Fiber, or Echo
• Skilled in ingesting, streaming, and parsing multi-format files (PDFs, large spreadsheets, API payloads) without heavy RAM overhead
• A proven track record of building robust connectors to external systems (ERPs, storefronts, email APIs) and processing dynamic incoming webhooks
• Experience working with transactional messaging/queuing systems (RabbitMQ, Kafka, or AWS SQS)
• Experience managing database connections (PostgreSQL, Redis) to guarantee order delivery
• Experience writing clean, well-tested code, including unit tests with go test and mock frameworks
• A background in graceful error handling for pipeline failures
• Proficiency in English at a B2+ level
