Title- Senior Technical Architect - Wireless
Location- Warwick,UK
Position Overview
We are seeking a Senior Technical Architect - Wireless to join our Technical Architecture
team and help design, standardize, and evolve a large-scale global enterprise wireless
environment.
This is an excellent opportunity for an experienced wireless engineer with CWNE or
CCIE Wireless-level expertise who is looking to transition into architecture, as well as an
architect who is relatively early in their architecture career.
The Senior Technical Architect – Wireless will work closely with Network Engineering
and other Technical Architects to develop wireless architectures, high-level designs,
standards, LLD templates, golden configurations, and implementation guidelines.
The organization is currently transitioning from Aruba to Cisco Meraki, providing the
successful candidate with an opportunity to play a significant role in the architecture and
standardization of the future wireless environment.
This is a Senior-level architecture position. The successful candidate will have
meaningful technical ownership while working alongside experienced Principal
Technical Architects who will provide mentorship and guidance.
Responsibilities
Wireless Architecture &amp; Design
 Develop high-level designs for enterprise wireless LAN (WLAN) environments.
 Develop and maintain wireless reference architectures, standards, and design
patterns.
 Design enterprise wireless solutions addressing coverage, capacity, RF
performance, resiliency, security, and operational requirements.
 Evaluate wireless technologies and designs for scalability, performance, security,
and operational effectiveness.
 Support the organization’s transition from Aruba to Cisco Meraki through
architecture, design, standards, and technical guidance.
 Participate in wireless technology evaluations, proof-of-concepts, and
architecture assessments.
 Contribute to wireless technology roadmaps and lifecycle planning.
Wireless Engineering Standards
 Develop and maintain wireless LLD templates, golden configurations, and
configuration standards.
 Establish standardized WLAN design and deployment practices that can be
consistently implemented by Engineering.
 Develop standards for RF configuration, SSIDs, authentication, roaming, RF
management, channel utilization, power, and other WLAN parameters.
 Partner with Network Engineering to validate and continuously improve wireless
standards and configurations.
 Validate wireless configurations and implementations against approved
architecture, standards, HLDs, LLDs, and golden configurations.
 Identify standards deviations and work with Engineering to resolve or formally
document exceptions.
Wireless Security &amp; Access Control
 Provide architecture and technical guidance for enterprise wireless authentication
and access control.
 Design and support integration between wireless infrastructure and Aruba
ClearPass and Cisco ISE.
 Develop standards for 802.1X, WPA2/WPA3-Enterprise, guest access, device
onboarding, and network access policies.
 Work with Security and Network Engineering to ensure wireless solutions meet
enterprise security requirements.
Technical Leadership
 Own assigned wireless architecture initiatives and deliverables.
 Review engineering designs and provide architectural guidance.
 Mentor wireless engineers and share technical knowledge.
 Create Architecture Decision Records (ADRs) and maintain architecture
documentation.
 Collaborate with LAN/WAN, Security, Cloud, End User Computer, and other
technical architects.
 Work with vendors and technology partners on wireless capabilities and
solutions.
Required Qualifications
 10+ years of enterprise wireless networking experience or equivalent depth of
wireless engineering experience.
 Strong hands-on experience designing, implementing, troubleshooting, and
optimizing enterprise WLAN environments.
 CWNE or CCIE Wireless-level expertise strongly preferred.
 Strong knowledge of:
o Enterprise WLAN architecture and design
o RF fundamentals and 802.11 technologies
o WLAN security and authentication
o 802.1X and RADIUS
o WPA2/WPA3-Enterprise
o RF management, channel planning, power management, and capacity
o Wireless roaming and client behavior
o WLAN troubleshooting and performance analysis
 Significant experience with Cisco Meraki wireless.
 Significant experience with Aruba AOS 8 wireless environments.
 Experience with Aruba ClearPass and/or Cisco ISE, with strong preference for
experience with both.
 Experience developing or working with wireless standards and design
documentation.
 Strong analytical, communication, and problem-solving skills.
 Ability to work effectively across Architecture, Engineering, and Security teams.
Preferred Qualifications
 CWNE certification or CCIE Wireless certification.
 Experience architecting large-scale global enterprise WLAN environments.
 Experience transitioning or migrating between enterprise wireless platforms.
 Experience developing wireless HLDs and LLDs.
 Experience creating and maintaining wireless golden configurations.
 Experience with wireless site surveys and RF analysis.
 Experience with wireless monitoring, assurance, and observability platforms.
 Experience with network automation and infrastructure-as-code concepts.
 Familiarity with cloud-managed wireless architectures.
Ideal Candidate
The ideal candidate is a strong technical wireless engineer ready to take the next step
into architecture, or an architect who is relatively early in their architecture career.
You do not need 20+ years of architecture experience. We are looking for someone with
strong wireless expertise, substantial real-world enterprise experience, technical
curiosity, and the desire to grow as an architect.
Experience with both Aruba AOS 8 and Cisco Meraki is particularly valuable as the
organization transitions its wireless platform from Aruba to Meraki.
An experienced Principal Architect will provide mentorship while the Senior Wireless
Architect progressively takes ownership of increasingly complex architecture initiatives.
Success in the Role
Success means becoming a trusted wireless architecture resource who can:
 Develop practical and scalable enterprise WLAN architectures.
 Help lead the architectural transition from Aruba to Meraki.
 Produce high-quality wireless HLDs and LLDs.
 Establish practical wireless standards and golden configurations.
 Develop repeatable wireless deployment and configuration practices.
 Validate wireless implementations for standards and architecture compliance.
 Provide technical guidance around ClearPass and ISE integration.
 Effectively bridge the gap between Architecture and Engineering.
 Progressively take ownership of larger wireless architecture initiatives.
