Optical Networking Engineer – Lead Design of Interconnect Solutions

About the role

Mesh Optical Technologies is looking for an Optical Networking Engineer to lead the network‑level design of its optical interconnect solutions. The role involves translating high‑level topology requirements into detailed link designs, evaluating hardware trade‑offs, and delivering deployment‑ready documentation.

Key responsibilities

• Trade and evaluate network architectures and interconnect topologies to guide optical hardware design.
• Design end‑to‑end optical interconnect solutions, specifying transceivers, fiber plant, cabling and link configurations.
• Conduct routing and switching hardware trade studies across switch, router and NIC platforms.
• Own network‑level signal and optical performance, including link budgets, modulation‑format trade‑offs, BER/OSNR/OMA, receiver sensitivity and FEC margin.
• Model and analyze link and channel performance to inform design and deployment choices.
• Develop comprehensive deployment documentation such as design guides, commissioning checklists and field service procedures.
• Define and execute test plans for characterization, interoperability and qualification of optical links in Ethernet, InfiniBand and other high‑speed architectures.
• Lead hardware bring‑up, link validation and acceptance testing in lab and on‑site environments.
• Troubleshoot hardware, firmware, software and link‑level issues across optical, electrical and firmware boundaries.
• Support module management interface bring‑up, CMIS configuration and firmware update workflows.
• Perform pre‑deployment site readiness assessments.

Required profile

• Proven experience leading network‑level design of optical interconnect solutions.
• Ability to evaluate hardware trade‑offs across switches, NICs and optical platforms.
• Strong analytical skills for link‑budget and performance modeling.
