The Role
As a Principal Architect, Network Research & Development, you will serve as a senior technical leader focused on shaping Lumen’s future network capabilities through deep architectural expertise, disciplined experimentation, and practical evaluation of emerging technologies. This is an individual contributor role designed for a highly credible architect who can operate at the intersection of advanced networking, emerging technology, technical strategy, and enterprise decision-making. The Principal Architect will help define hypotheses, design experiments, evaluate vendor and partner capabilities, develop reference architectures, and provide clear technical guidance on whether emerging capabilities should be stopped, continued, scaled, or transitioned into future roadmap consideration.
Location
This is a remote opportunity open to candidates located anywhere in the U.S.
The Main Responsibilities
Serve as a senior technical authority for Network R&D initiatives, providing architectural direction across emerging network technologies, advanced infrastructure concepts, and future capability exploration.
Evaluate emerging technologies such as quantum networking, post-quantum cryptography, next-generation optical and fiber systems, autonomous networks, AI infrastructure, programmable networks, edge and distributed compute, digital twins, and advanced security capabilities.
Develop reference architectures, technical design patterns, proof-of-concept approaches, and decision frameworks that help determine whether emerging capabilities have relevance for Lumen’s future network strategy.
Lead deep technical analysis of vendor, startup, academic, national lab, open-source, and consortium-led innovation opportunities, ensuring external partnerships produce actionable insight and usable learning.
Design and guide experiments, pilots, lab validations, simulations, and technical assessments that test feasibility, interoperability, scalability, resiliency, security, cost, and operational fit.
Translate ambiguous technical findings into clear architecture implications, risk assessments, trade-off analyses, and recommendations for senior technical and business stakeholders.
Collaborate with Network Engineering, Architecture, Product, Security, Operations, Finance, Legal, Procurement, and external partners to connect R&D work to enterprise priorities and future customer needs.
Identify technical dependencies, integration considerations, standards implications, operating model impacts, and commercialization pathways for validated capabilities.
Provide thought leadership on future network evolution, including how emerging technologies may influence network architecture, product enablement, automation, resilience, security, and customer differentiation.
Help establish disciplined technical governance for R&D work, including architecture reviews, documentation standards, learning milestones, technical exit criteria, and stop/continue/scale recommendations.
Represent Network R&D in technical forums, partner discussions, internal architecture reviews, standards conversations, and executive-level technical briefings.
Maintain a strong external view of technology shifts, market signals, standards activity, partner ecosystems, and competitive innovation that may create future strategic advantage for Lumen.
What We Look For in a Candidate
Bachelor’s degree in engineering, computer science, electrical engineering, telecommunications, applied science, or a related technical field; advanced degree preferred.
12+ years of experience in network architecture, network engineering, advanced technology strategy, R&D, product engineering, platform engineering, security architecture, or a related technical discipline.
Deep technical expertise in one or more advanced network domains such as optical and transport systems, IP networking, programmable networks, cloud-native infrastructure, automation, AI-enabled infrastructure, edge/distributed compute, security architecture, or next-generation access technologies.
Demonstrated ability to evaluate emerging technologies and convert technical uncertainty into structured experiments, architectural options, decision points, and business-relevant recommendations.
Ability to operate in ambiguity, quickly learn new technical domains, separate signal from noise, and make sound recommendations with incomplete or evolving information.
Strong executive and technical communication skills, including the ability to explain highly complex concepts to senior leaders, peer architects, engineering teams, vendors, and non-technical stakeholders.
Proven ability to influence without direct authority and work effectively across matrixed teams, technical SMEs, external partners, and leadership stakeholders.
Commitment to disciplined experimentation, including defining hypotheses, success measures, learning milestones, technical constraints, and kill criteria.
Ability to mentor other technical contributors and help elevate architectural thinking, documentation quality, and technical decision-making across the organization.
Preferred Qualifications
Experience contributing to R&D, innovation, advanced architecture, emerging technology, lab, incubation, or future-state strategy work within a telecommunications, cloud, infrastructure, security, or deep technology environment.
Exposure to quantum technologies, post-quantum cryptography, QKD, photonics, next-generation fiber, advanced optical systems, AI infrastructure, autonomous networks, digital twins, programmable network architectures, or advanced security models.
Experience designing or leading technology pilots, proof-of-concepts, simulations, lab validations, vendor co-development efforts, academic collaborations, national lab engagements, standards participation, or startup evaluations.
Understanding of intellectual property considerations, standards bodies, vendor partnership models, co-development terms, licensing approaches, or commercialization pathways for emerging technology work.
Experience representing an organization externally with credibility in technical forums, industry groups, partner discussions, vendor briefings, or innovation ecosystems.
Strong curiosity and external orientation, with a demonstrated ability to connect market signals, technology trends, customer needs, and enterprise strategy into practical architecture recommendations.
