We’re looking for a Lead/Senior Golang Developer to join our team and build the backend of a high-performance, distributed B2B SaaS platform designed for companies that need reliable, scalable workflow engines and data pipelines.

This is a rare opportunity to work on a deeply technical product from the ground up, solve real scalability challenges, and push Go to its limits.

⚠️ Please DO NOT apply if you do NOT have proven, hands-on experience working with high-load systems and performance-critical applications.

🚀 Project

We are developing a highly configurable internal platform designed to orchestrate high-load workflows, event-driven processes, and data-intensive tasks at scale.

• Work closely with product and frontend engineers to align backend logic with business goals
• Participate in architecture reviews, code reviews, and documentation
• Contribute to internal libraries, tooling, and engineering best practices
• Occasionally join technical calls with partners or clients (optional but appreciated)

🛠 Required Skills & Experience

• 7+ years of backend development experience
• 5+ years of hands-on Go development
• Strong experience with Kafka and Redis (mandatory)
• Experience working with ScyllaDB, ClickHouse, PostgreSQL, or MongoDB in high-load contexts
• Deep understanding of distributed systems, concurrency, and message-driven architecture
• Solid grasp of microservices architecture, service discovery, and networking
• Experience with Docker, Kubernetes, and AWS
• Familiarity with CI/CD practices and observability tools (e.g., Prometheus, Grafana, Jaeger)
• Strong testing habits (unit, integration, E2E)
• Proficiency in clean code principles, OOP, SOLID, and idiomatic Go

🧠 Engineering Mindset

• Build for performance, scale, and resilience
• Write simple, readable, and maintainable code
• Anticipate edge cases and system failure modes
• Push for continuous improvement of processes, tools, and infrastructure
• Comfortable balancing tech debt with delivery speed

👤 Personal Qualities

• Proactive and responsible (IT'S A MUST!)
• Comfortable working independently in a remote setup
• Strong team player who shares knowledge and supports others
• Excellent communication skills (written and verbal)
• Eager to grow and adopt new technologies
