Lead discovery and technical workshops: Assess feasibility early by translating bandwidth, locations, diversity, service dates, and growth needs into network requirements, including capacity, latency, route diversity, resiliency, and interfaces.
Design high-capacity fiber solutions: Architect optical transport, wavelength, Ethernet, Managed Optical Fiber Networks, DCI, and dark fiber solutions. Evaluate existing fiber and capacity, route alternatives, and new-build needs, and compare the technical and economic trade-offs among dark fiber, wavelengths, Ethernet, and managed transport.
Develop proposals and recommendations: Create architecture diagrams, technical proposals, proactive proposals, and RFP responses with clear assumptions, risks, timelines, and cost or ROI inputs. Present recommendations to engineering, business, and executive stakeholders.
Make the complex simple: Simplify complex technology for executives while maintaining credibility with network architects.
Manage risks, escalations, and handoff: Partner with sales, product, construction and engineering, operations, and delivery teams. Identify technical and implementation risks, support high-priority escalations, and ensure an effective post-sale handoff.
Scale what works: Create reusable solution patterns, mentor other technical-sales professionals, and bring recurring customer needs and emerging demand patterns into product and network plans.
What you'll bring
Typically 8+ years of relevant network-infrastructure experience, including significant customer-facing work in solutions architecture, sales engineering, consulting, or technical presales, supporting large, complex opportunities.
Extensive experience with optical transport or fiber-based network solutions, with strong knowledge of DWDM, wavelength services, OTN, and Carrier Ethernet.
Understanding of optical link budgets, fiber loss, amplification, regeneration, protection, and route diversity.
Experience with high-capacity metro, long-haul, or DCI architectures.
Demonstrated ability to lead discovery, develop proposals, and explain complex designs to technical and business audiences, with strong consultation and cross-functional collaboration skills, and supporting implementation across customer and internal stakeholder groups.
Sound judgment on solution cost, feasibility, risk, and customer outcomes, with strong problem-solving and data-driven decision-making under changing conditions.
A proactive, action-oriented mindset, with a proven ability to influence buying decisions, shape opportunities, and contribute to revenue growth.
Bachelor's degree (BS/BA) in a relevant field or equivalent practical experience.
How you'll work
Start with the customer: Use customer needs and market demand to guide solution priorities and deliver meaningful value.
Move with speed and purpose: Focus effort on high-value outcomes, simplify decisions, and act with appropriate urgency.
Challenge and improve relentlessly: Question assumptions and improve solutions, processes, and customer outcomes.
Strengthen the team: Share knowledge, collaborate across functions, and help colleagues perform at their best.
Supervisor: No
