VX Fiber is looking for Backend Developers to help build and evolve the systems behind our global SaaS platform for fibre network operations.

You might be early in your career and ready to grow, or an experienced developer who can take broader technical ownership. What matters most is that you enjoy working with modern technology to solve real problems.

About the role

As a Backend Developer at VX Fiber, you will design, build, and maintain backend services that power our fibre network SaaS platform. Our backend stack is built around Go, gRPC, Protocol Buffers, Temporal, MongoDB, PostgreSQL, Docker, Nomad, Consul, Vault, and AWS.

You will work with distributed systems, domain-driven design, automation, integrations, and operational workflows that support network owners, ISPs, field operations, provisioning, service activation, and subscriber services.

You will join a self-organizing, cross-functional team where architecture, automation, product thinking, and technical quality are part of everyday work.

Depending on your experience and interests, you could be involved in:

Design, develop, and maintain backend services in Go.

Use modern AI-assisted and agentic coding workflows to improve speed, quality, and developer productivity.

Build APIs, integrations, workflows, and domain services using gRPC, Protocol Buffers, GraphQL, and Temporal.

Collaborate with frontend developers, product, platform, operations, and network specialists.

Work with databases such as MongoDB and PostgreSQL.

Improve reliability, scalability, performance, and observability across distributed systems.

Contribute to system architecture, technical proposals, and design discussions.
