Note: The job is a remote job and is open to candidates in USA. Lumen Technologies is transforming how businesses connect, secure, and scale in an AI-driven world. The Network Design Engineer V will lead advanced engineering efforts to develop and implement secure WAN/transport solutions for the Department of the Air Force C3BM/ABMS program, translating operational and cybersecurity requirements into actionable field work packages.
Responsibilities
- WAN Architecture & Design Engineering
- Develop WAN/transport design recommendations for mission networks: site connectivity, segmentation, resiliency, and performance engineering across classified and unclassified enclaves
- Define engineering requirements, interfaces, and implementable WAN designs, including L0 circuit configurations and CLLI circuit-route options across CONUS/OCONUS; optionally address routing, addressing, QoS, encryption, and boundary protection
- Develop optimized WAN transport options using OTN and ITU‑T standards (G.709, G.798, G.872); apply MPLS/IP, Ethernet, VPN/IPsec, SD‑WAN, and modern secure access patterns (SASE/SSE) where applicable
- Propose WAN work package options to SAIC technical leadership to support engineering trades before implementation; deliverables may include HLD/LLD, logical/physical diagrams, IP plans, L0 routing/QoS policies, security boundary requirements, BOM/part lists, rack elevations (as applicable), configuration templates, and interface cut sheets
- Support the SAIC Chief Engineer with MOPs, implementation plans, cutover schedules, rollback procedures, and test/validation plans; participate in technical reviews and change control; identify/mitigate risks per work package
- Recommend optimized WAN solutions for current/long-range planning; partner with technical leads to select tools/technologies that improve efficiency, reduce cost, and increase customer satisfaction
- Create/maintain engineering and compliance evidence (device configuration baselines, DISA STIG notes/checklists, boundary descriptions, diagrams, status reports) to support audits and RMF/ATO
- Support operational projects and maintenance windows; assist implementation teams during turn-ups, migrations, and service transitions
- Recommend automation/standardization of repeatable engineering tasks (configuration generation, validation checks, documentation workflows) consistent with program approvals
- Troubleshoot complex hardware/software/network issues (as requested); document problems, root causes, and resolutions; feed lessons learned into package templates and standards
- Support WAN capacity planning across sites/segments (bandwidth, optical/Carrier Ethernet where applicable, routing headroom, power/cooling constraints, lifecycle/EOL)
- Support L0 circuit delivery/integration/activation and service migrations: coordinate with providers, validate acceptance criteria, and update as-built documentation
- Provide inputs to design review packages; update network drawings (e.g., Visio) and route maps to reflect approved designs and as-built changes
- Develop ROM estimates and cost models for new sites, routes, and WAN services
- As requested by the PM and/or Chief Engineer, serve as technical liaison among teams to align design intent, circuit turn-up activities, and field execution
- Provide Tier 3/4 troubleshooting and root-cause analysis for WAN/transport issues and recommend corrective actions
- Support RMF/ATO by producing required network engineering evidence: diagrams; port/protocol/service documentation; boundary descriptions; STIG checklists/implementation notes; and as-built configurations
- Deliver technical design reviews, implementation-readiness briefings, and mission-impact assessments to the SAIC Chief Engineer and operational teams
Skills
- US Citizenship is required
- Active TS/SCI or SCI Eligible
- IAT Level I/II/III Certification
- Travel is required
- Education/experience: BA/BS +17 years; or MS + 13 years; or PhD/JD + 10 years related experience
- 14+ years progressive WAN/transport engineering, network architecture, or telecommunications experience, including deployable implementation/job packages
- Deep expertise in OTN and ITU-T standards (G.709, G.798, G.872)
- MPLS/IP, Ethernet, VPN/IPsec overlays, and enterprise/carrier WAN design patterns
- Routing/traffic engineering (BGP, OSPF/ISIS), path control, convergence, SD-WAN and secure connectivity (SASE/SSE), segmentation/policy design, QoS (marking/queuing/shaping), performance engineering, capacity planning
- Network security, boundary protections, and Zero Trust; field-ready engineering packages (logical/physical diagrams, IP plans, BOMs, config templates, implementation steps, cutover/rollback, test/validation)
- Task/work-order execution support: design reviews, implementation readiness coordination, and design-to-field discrepancy resolution
- Technical writing/communications: concise engineering documentation and briefings for technical and non-technical stakeholders
- Consultative skills: rapport, fact-finding, requirements definition, options/recommendations, follow-through, customer focus; thrives with competing priorities
- Previous Lumen Network Architecture experience required
