Job Summary

The Senior Optical Engineer is responsible for designing, engineering, and supporting the continued growth of Ziply Fiber’s optical transport network. This role focuses on ROADM-based DWDM, OTN, and coherent 100G/400G wavelength services, while helping align the optical layer with the IP/MPLS core network. As a senior technical contributor, this position provides optical engineering expertise, technical leadership, and mentorship, while partnering with network architecture and operations to deliver a scalable, reliable, and future-ready transport network.

Essential Duties and Responsibilities: 

The Essential Duties and Responsibilities listed below are a range of duties performed by the employee and not intended to reflect all duties performed.

Design & Planning

·        Perform optical link engineering — wavelength and route planning, optical power and loss budgets, OSNR analysis, chromatic dispersion and PMD management, and EDFA/Raman amplifier placement.

·        Design ROADM-based DWDM topologies (fixed and flex-grid) and specify coherent transponders and muxponders for 100G/400G wavelength services.

·        Own the end-to-end design of DWDM and optical transport solutions, developed in partnership with network architecture, and define the technical standards and reference designs that guide implementation.

·        Deliver wavelength services to the core IP network in a way that complements the architecture and redundancy goals for IP services.

·        Plan and prepare detailed equipment installation specifications and drawings.

·        Streamline and standardize implementation methods and procedures to support scale.

·        Partner with systems engineering to automate network provisioning and turn-up tasks wherever possible.

Technical Leadership & Strategy

·        Serve as the optical-layer subject-matter expert, providing technical guidance and mentorship to engineers and leading design and peer reviews.

·        Develop multi-year optical capacity and technology roadmaps, including migration planning from legacy SONET/TDM toward OTN and coherent transport.

·        Lead vendor and technology evaluation and selection, including RFI/RFP processes, lab and proof-of-concept testing, and standardization of platforms and methods.

Deployment & Turn-up

·        Commission and turn up optical systems using OTDRs, optical spectrum analyzers, and optical power meters; validate span loss, OSNR, and channel power before service activation.

·        Isolate and resolve optical-layer faults end-to-end across multi-vendor network segments.

·        Participate in the oversight and installation of DWDM and IP network layers.

·        Coordinate with third-party fiber providers as needed to successfully turn up DWDM systems.

·        Provision DWDM wavelengths for customers and for internal core-network capacity.

·        Provision DWDM wavelengths and associated muxes to deliver OC-192 circuits to the TDM team. The DWDM team’s minimum circuit size is OC-192/10G; smaller circuits are handled by the TDM team.

·        Connect DC power to DWDM equipment and/or routers.

·        Ensure new IP POPs are
