Title: 5G Core & Digital Twin Network Solution Architect

Function: IT, Telecom & Internet

Location: Poland - Krakow

Work Model: Remote

Our customer, a leading top-tier Mobile Network Operator (MNO), is actively pioneering the next evolution of telecommunications by researching and implementing Digital Twins for telecom networks. As part of a strategic initiative to achieve Level 4 and Level 5 Autonomous Networks, this project focuses on assembling an elite team of domain experts and consultants to explore emerging opportunities, run feasibility studies, and design cutting-edge architectures and industry best practices. By bridging real-time network telemetry, 5G Core architecture, and predictive digital twin modeling, the team will lay the foundational framework for zero-touch automation, intelligent traffic orchestration, and fully autonomous telecom operations.

Responsibilities

Lead the solution architecture and technical strategy for 5G Core (5GC) and Digital Twin network deployments, integrating real-time telemetry, predictive analytics, and network emulation.
Architect real-time Digital Twin models for 5G Core networks to enable traffic modeling, anomaly detection, automated testing, and zero-touch network management.
Define end-to-end cloud-native architecture guidelines aligning 5G Service-Based Architecture (SBA) with digital twin simulation platforms.
Serve as the technical authority across project lifecycles: software installation, configuration design, NFV/CNF orchestration, component integration, and service migration.
Define comprehensive User Acceptance Test (UAT) frameworks, sandbox validation suites, and digital twin simulation scenarios.
Identify risk profiles, capacity constraints, and system impacts of new network functions using digital twin predictive modeling prior to live rollouts.
Support pre-sales engineering, solution analysis, technical cost estimation, and RFP/RFI responses for 5G and digital twin transformation projects.
Lead cross-functional delivery teams, customer workshops, and technical discussions with both C-level stakeholders and engineering teams.
Manage customer requirements, technical risk recommendations, and solution evolution roadmaps from pre-sales to post-deployment handover.
Identify expansion and add-on sales opportunities by leveraging digital twin insights to optimize customer network performance.
Mentor cross-functional engineering teams, foster knowledge sharing, and drive technical best practices in telco cloud and digital twinning.
Collaborate closely with 3rd-party vendors, system integrators, and open-source communities.

Requirements

Education: Master’s degree in Computer Science, Telecommunications Engineering, Electrical Engineering, or a related field.
Minimum 5 years of hands-on experience in Telco Cloud system deployment, testing, and network function orchestration (Kubernetes, OpenStack, CNFs/VNFs).
Proven track record as a Solution Architect with deep expertise in 5G Core (SBA, AMF, UPF, SMF, NRF), 4G EPC, and IMS environments.
Demonstrated experience or strong working knowledge of Digital Twin frameworks, simulation platforms, network emulation tools, data pipeline integration, and predictive network modeling.
Standards & Protocols: In-depth knowledge of industry standards including 3GPP (5G SA/NSA), ETSI (NFV/MANO), CNCF, TM Forum, IETF, and MEF-LSO.
Exceptional ability to communicate complex technical concepts clearly to non-technical stakeholders and executive leadership.
Strong strategic thinking, relationship-building, and cross-functional leadership skills.
