Description

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers.

You will design the connectivity behind Lambda's next data center, backbone route and customer interconnect.

Responsibilities

  • Design the Network: Develop physical and optical connectivity designs for data centers, points of presence, backbone routes and customer interconnects.
  • Translate customer and network requirements into routes, capacity plans, equipment needs and acceptance criteria, working within Network Engineering's and HPC architecture.
  • Compare dark fiber, wavelength, internet transit and interconnection options on latency, resilience, total cost, delivery time and room for expansion.
  • Validate route diversity and identify shared conduits, building entrances, fiber extensions and other dependencies that could compromise a design.

Develop Solutions with Suppliers

  • Work with carrier engineering teams to develop routes, extend reach and resolve coverage, site access or capacity constraints.
  • Evaluate new and existing suppliers, gather technical proposals and budgetary quotes, and recommend options with clear tradeoffs.
  • Work with optical and network equipment partners on alternatives when fiber availability, equipment lead times or cost put a build at risk.

Take Designs into Delivery

  • Produce a complete design package for Network Engineering approval, then work with Delivery on the build schedule, dependencies and acceptance requirements.
  • Resolve design questions during delivery and take revisions back through Network Engineering review when site or supplier conditions change.

Requirements

  • Experience designing or developing carrier, cloud or data center connectivity, with designs that have progressed from requirements into delivery.
  • Practical knowledge of dark fiber, wavelength services, optical transport and internet interconnection.
  • Ability to assess physical route diversity, equipment dependencies and capacity needs beyond what a route map alone shows.

Nice To Have

  • Experience designing long-haul optical networks or dense wavelength division multiplexing (DWDM) systems.
  • Experience with private cloud connectivity, internet exchanges or large compute deployments.

Benefits

  • Generous cash & equity compensation
