Wireless Solutions Architect

Wireless Solutions Architect – 5G SA | O-RAN | vRAN | Cloud-Native RAN

Location: Reading – 2 days per month in Office

Type: Permanent

We are looking for an exceptional Wireless Solutions Architect to join our forward-thinking technology team, leading the design and delivery of next-generation 5G Standalone (SA) wireless solutions with a strong focus on Open RAN (O-RAN), virtualised RAN (vRAN), and xRAN architectures .

In this role, you will architect and deliver end-to-end cloud-native wireless solutions that are scalable, interoperable, and aligned with the future of mobile networks. You will be at the forefront of network disaggregation and innovation , shaping the evolution of RAN architectures across private and public 5G deployments.

Key Responsibilities

• Design and architect cloud-native wireless network solutions based on O-RAN, 5G SA, vRAN, and xRAN frameworks.
• Define multi-vendor RAN system architecture , including RU/DU/CU components and interfaces (O1, O2, E2).
• Lead the end-to-end design, integration, and validation of disaggregated RAN technologies.
• Evaluate and optimise fronthaul, midhaul, and backhaul solutions , with a focus on O-RAN Split 7.2x .
• Work cross-functionally with engineering, product, and external vendors to align solutions with technical and business goals.
• Produce clear architecture documentation , deployment guides, and performance tuning recommendations.
• Conduct RF planning , propagation modelling, and system performance optimisation .

Required Expertise

• Deep understanding of wireless network architecture : 5G SA, Open RAN, vRAN/xRAN.
• Expertise in cloud-native networking , virtualisation (Kubernetes, Docker), and RAN disaggregation.
• Proven experience integrating RU/DU/CU components within open, interoperable frameworks.
• Strong grasp of O-RAN architecture (SMO, RIC) and interfaces (O1/O2/E2).
• Hands-on experience with vRAN/xRAN deployments , preferably involving Rakuten Symphony, Mavenir, Parallel Wireless, Nokia, or Ericsson .
• Practical knowledge of RF principles , beamforming, Massive MIMO , and DSS.
• Familiarity with network automation tools : Linux, Python, Ansible, Bash.
• Solid understanding of 5G Core (gNodeB, AMF, SMF, UPF) and related interfaces.
• Knowledge of network slicing, QoS , and Multi-access Edge Computing (MEC) .
• Experience working with orchestration and management frameworks (ONAP, OSM) and REST APIs.
• Ability to translate complex designs into practical, scalable solutions and lead technical delivery across teams.

Desirable Skills

• RF planning and system performance modelling with industry-standard tools.
• Experience with large-scale telecom network design and deployments.
• Strong stakeholder engagement, technical leadership, and communication skills.
• Ability to operate in multi-vendor, fast-paced environments with a collaborative mindset.
