Senior Fiber Network Design Engineer

Tenarai; Michigan; On-site; USD 90,000 - 140,000; Full time

Job summary

Tenarai is seeking a Connectivity Engineer to own end-to-end fiber connectivity design across Metro Ring markets, long-haul routes, and ILA sites. You will coordinate cross-functional teams to ensure seamless network continuity from endpoints to data centers.

The role emphasizes splice design ownership, proactive capacity planning, and timely implementation of circuit connections, with a focus on LR-TPOR readiness and scalable network deployment.

Qualifications

• Experience in fiber optic network design, connectivity planning, or outside plant (OSP) engineering.
• Understanding of splice design, fiber strand management, and physical layer network architecture.
• Familiarity with circuit routing, ILA sites, and long-haul fiber infrastructure.
• Strong cross-functional coordination skills with the ability to work across multiple engineering and delivery teams.
• Ability to manage multiple concurrent design and implementation projects.

Responsibilities

• Design connectivity solutions for Metro Ring markets, including long-haul routes between markets, capacity design hand-offs to midpoints, data centers, and ILA sites
• Develop and maintain inter-market routing designs to support current and future network demand
• Assign circuits to strands within markets in close coordination with cross-functional teams including NIE, Sourcing Managers, DSE, and FDE
• Take full ownership of splice design and implementation for all circuit connections from origin to destination
• Focus on Long-Range Turnover Planning and Ordering Readiness (LR-TPOR) to proactively stay ahead of network demand and capacity requirements
• Partner with the Sourcing Managers team to identify and resolve gaps in circuit A-to-Z continuity by coordinating strand connection orders as needed
• Design and implement ILA pre-term installations to ensure readiness for future network activation and capacity growth
• Manage the full lifecycle implementation of all splice designs for Metro Ring markets, long-haul ties, and ad-hoc routing requirements
• Ensure splice designs meet quality standards and are delivered on schedule to support network deployment timelines

Job description

The Connectivity Engineer is responsible for the end-to-end design, coordination, and implementation of physical fiber connectivity across Metro Ring markets, long-haul (LH) routes, and inter-market routing infrastructure. This role serves as the primary owner of splice design and physical connection implementation, ensuring seamless network continuity from market endpoints through midpoints, data centers, and in-line amplifier (ILA) sites.

Key Responsibilities

Network Connectivity Design

• Design connectivity solutions for Metro Ring markets, including long-haul routes between markets, capacity design hand-offs to midpoints, data centers, and ILA sites
• Develop and maintain inter-market routing designs to support current and future network demand
• Assign circuits to strands within markets in close coordination with cross-functional teams including Network Infrastructure Engineering (NIE), Sourcing Managers, Design & Structural Engineering (DSE), and Fiber Design Engineering (FDE)

A-to-Z Physical Connection Ownership

• Take full ownership of splice design and implementation for all circuit connections from origin to destination
• Focus on Long-Range Turnover Planning and Ordering Readiness (LR-TPOR) to proactively stay ahead of network demand and capacity requirements

Strand Connection Order Management

• Partner with the Sourcing Managers team to identify and resolve gaps in circuit A-to-Z continuity by coordinating strand connection orders as needed
• Design and implement ILA pre-term installations to ensure readiness for future network activation and capacity growth

Splice Design Implementation & Management

• Manage the full lifecycle implementation of all splice designs for Metro Ring markets, long-haul ties, and ad-hoc routing requirements
• Ensure splice designs meet quality standards and are delivered on schedule to support network deployment timelines

Qualifications

Required

• Experience in fiber optic network design, connectivity planning, or outside plant (OSP) engineering
• Understanding of splice design, fiber strand management, and physical layer network architecture
• Familiarity with circuit routing, ILA sites, and long-haul fiber infrastructure
• Strong cross-functional coordination skills with the ability to work across multiple engineering and delivery teams
• Ability to manage multiple concurrent design and implementation projects.

Preferred

• Experience with network capacity planning and demand forecasting
• Knowledge of fiber splicing standards, OTDR testing, and fiber characterization
• Background working within large-scale data center or hyperscale network environments.
• Proficiency with GIS tools, fiber management systems, or network design platforms

Core Competencies

• Technical Expertise - Deep understanding of physical fiber connectivity and network topology
• Cross-Functional Collaboration - Proven ability to coordinate across NIE, Sourcing Managers, DSE, and FDE teams
• Proactive Planning - Forward-thinking approach to stay ahead of demand (Long Range Planning focus)
• Ownership & Accountability - End-to-end ownership of designs from concept through implementation
• Problem Solving - Ability to identify and resolve continuity gaps and routing challenges.
