Network Advisory, Principal Consultant
  
Wanted:  Dynamic and creative individuals ready to connect with a like-minded team. You’ll enjoy all the autonomy you need to help our clients prepare for the future. Free reign for free spirits doesn’t mean you’ve got to go it alone. Over 1400 teammates from around the globe are eager to help you out when things get down to wire. Their expertise will put you on the winning path and keep you there.
 
Position Overview
 
This is a senior advisory role responsible for leading complex client engagements focused on network strategy, readiness, and sourcing. The Principal Consultant owns end-to-end delivery of advisory engagements, from assessing current-state network architecture, operations, and organizational readiness through defining future-state strategies and supporting sourcing and decision-making efforts.  The role is centered on helping clients evaluate and evolve their networks to support current and emerging demands, including AI-enabled workloads and operations, software-defined networking, network security, cloud networking models, and enterprise connectivity. The Principal Consultant acts as an independent advisor, providing evidence-based challenges to client assumptions while demonstrating sound judgment in aligning to client direction.  This position requires deep experience in network strategy, including enterprise network architectures, carrier services, infrastructure platforms, and the operational and commercial considerations that shape real-world outcomes. Success in this role depends on the ability to navigate ambiguity, balance competing technical, financial, and organizational constraints, and translate complex analysis into clear, executive-level guidance.
