Job Description

We are looking for a Staff Software Engineer, Mobile Network Architecture & Connectivity to define and drive the technical architecture that will enable the evolution of our telecommunications ecosystem toward Full Mobile Network Operator (MNO) capabilities.

This is a senior individual contributor role for a technical leader who combines deep expertise in Telco architecture with a strong background in software and platform engineering. The idóneo candidate understands telecommunications operations end-to-end and can translate complex Telco capabilities into modern, scalable, resilient, secure, observable,



and highly automated technology platforms.

In this role, you will define the target architecture and technical roadmap across the Telco ecosystem, connecting digital customer experiences, CRM/BSS, provisioning, OSS, charging, SIM/eSIM, Mobile Core, IMS, subscriber management, policy control, network services, interconnection, and roaming.

You will establish how these capabilities should be structured, integrated, and operated, including system boundaries, ownership models, systems of record, APIs, events, data flows, integration patterns, and orchestration responsibilities. You will also help determine which strategic capabilities should be developed and owned internally, built in partnership with technology providers, or delivered through external vendors.

As a Staff Software Engineer, you will provide technical leadership across engineering, architecture, product, operations, and external technology partners. You will influence critical architectural decisions, establish technical standards, evaluate vendor solutions, identify opportunities for capability internalization, and guide the modernization of Telco platforms.
