Job summary

Ziply Fiber is seeking a Senior Optical Engineer in Kirkland, WA to design, engineer, and support the growth of our optical transport network. You will focus on ROADM-based DWDM, OTN, and coherent 100G/400G services, aligning the optical layer with the IP/MPLS core and mentoring junior engineers.

You will lead multi-year capacity planning, vendor evaluations, and deployment turn-ups, driving standards and reference designs while supporting the core network with scalable, reliable transport

Qualifications

• Minimum of five (5) years of network engineering experience, including at least three (3) years in DWDM and optical transport.
• Strong IP/MPLS networking knowledge — including BGP, IS-IS or OSPF, and MPLS — in a packet-optical or converged core environment.
• Working knowledge of DWDM/ROADM, OTN (G.709), SONET/SDH, and coherent 100G/400G wavelength services
• Understanding of optical fundamentals: single-mode vs. multi-mode fiber, optical power/loss budgets, OSNR, chromatic dispersion, PMD, and optical amplification (EDFA/Raman).
• Experience provisioning or commissioning telecommunications network elements such as routers, switches, DSLAMs, PON, TDM, VoIP, and DWDM.

Responsibilities

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