Senior Back-end Developer (Golang)

Requirements

We’re looking for a Senior Backend Developer with proven experience building production-grade backend systems in Go (Golang). You should be comfortable working in a team of specialists, taking ownership of complex components, and continuously improving system reliability and code quality.

• Experience: strong backend engineering background with substantial hands-on development experience in Golang.
• Backend fundamentals: solid understanding of RESTful APIs (or similar paradigms), concurrency, performance considerations, and data modeling.
• Quality & testing: ability to design testable code and implement unit/integration tests as part of your workflow.
• Reliability & observability: experience with logging, monitoring, and troubleshooting production systems.
• Collaboration: you can work effectively with cross-functional teams (product, QA, and engineering) and translate requirements into technical deliverables.
• Security mindset: you think proactively about secure design, input validation, and safe dependency practices.
• Communication: clear written and verbal communication, constructive code reviews, and the ability to share tradeoffs and recommendations.

We’ll particularly value senior-level judgment, consistent delivery, and a willingness to learn from—and contribute to—seasoned professionals.
