About the role

Gcore builds managed DNS infrastructure and offers a Traffic Management System that steers client traffic for performance, availability and resilience. As a Software Engineer (Go), you will design, build and maintain the Traffic Management System API (a Go service) and the agent that applies routing configuration on edge nodes, helping consolidate edge routing onto a single control plane.

• Strengthen reliability with strong test coverage (config rendering and end-to-end pipeline tests), metrics and observability.
• Collaborate with cross-functional teams to optimise system performance, reliability and resiliency.

Required profile

• At least 5 years of experience in software engineering and 3+ years with Go.
• Ability to work independently with minimal supervision, owning work end-to-end and communicating proactively.
