Senior Golang Developer

About the role

This Senior Golang Developer role focuses on leading the development of scalable and reliable backend services. The work involves driving architectural decisions within a microservices ecosystem, evaluating technology choices, and defining integration patterns. A key aspect is optimizing application performance, which includes profiling CPU and memory usage, fine-tuning Go's garbage collector, and leveraging concurrency primitives.

The position also requires strong database expertise, specifically designing efficient data models and optimizing complex queries in PostgreSQL/MySQL to handle high read/write workloads. Building observability into services through metrics, logging, and distributed tracing is essential. Candidates will participate in incident investigations, performing root cause analysis across various system layers.

Beyond technical execution, this role involves significant collaboration and mentorship. The Senior Golang Developer will conduct code reviews, share technical knowledge, and guide other engineers. Success in this position means delivering production-ready features quickly and reliably, working closely with DevOps, QA, Product, and other engineering teams.
