Network Solutions Architect (OSS/Telco) - Hybrid Portugal (Porto or Lisbon)

ABOUT THE OPPORTUNITY

A major player in the telecommunications sector is looking for a seasoned Network Solutions Architect to join a high-impact consulting engagement in Portugal. This is a senior-level opportunity for someone who thrives at the intersection of complex network architecture and enterprise-scale solution design — working on meaningful infrastructure that connects people and services at scale.

PROJECT & CONTEXT

You'll be working at the heart of a large-scale Telco environment, contributing to end-to-end architecture across OSS domains and multiple network layers. The scope spans RAN, Mobile Core, Transport, IP Core, and Service Platforms (including TV and SIP), with a strong focus on how OSS solutions enable automation, assurance, and operational readiness across the enterprise. Expect complex, multi-stakeholder projects where your architectural decisions carry real weight and long-term impact.

WHAT WE'RE LOOKING FOR

• Solid understanding of Telco business models and processes, with the ability to connect technical architecture to business outcomes
• Proven experience designing E2E solutions with clear placement of OSS within the broader enterprise architecture
• Deep knowledge of how architecture enables interworking across network domains: RAN, Mobile Core, Transport, IP Core, and service platforms such as TV and SIP
• In-depth understanding of OSS solutions and components across Assurance, Configuration, Planning, and Readiness domains
• Strong grasp of OSS and Automation Architectures, including modern approaches to network operations at scale
• Technical background in Microservices and Automation Platforms, applied in production or large-scale environments
• Hands-on experience in engineering and software architecture design, with the ability to produce and communicate robust architectural artefacts
• Demonstrated track record on complex, large-scale projects — from design through delivery
• Strong analytical and problem-solving skills with the ability to navigate ambiguity and drive clarity in undefined situations
• Effective communication and organisational skills, with the confidence to lead technical conversations across mixed audiences
• English at B2 level (Upper Intermediate) or above — essential for stakeholder engagement and project documentation
• Comfortable operating outside the comfort zone, acquiring new skills as the landscape evolves

NICE TO HAVE

• Previous project management experience or formal PM methodology exposure (e.g., PMP, PRINCE2)
• Familiarity with TM Forum frameworks (e.g., eTOM, TAM, Open APIs)
• Experience with cloud-native network deployments or NFV/SDN environments
• Exposure to CI/CD pipelines and DevOps practices applied to network or OSS solutions
• Background in solution architecture within a consulting or systems integration context
