Job summary

Lambda, The Superintelligence Cloud, Bellevue/San Francisco area, seeks a Senior Staff Network Engineer to own end-to-end network architecture, lead multi-team projects, and drive scalable designs for AI workloads.

You will write RFCs and designs, mentor engineers, and push automation to reduce manual ops. Expect day-2 operations and on-call rotations to ensure reliability and observability.

Qualifications

• Experience designing end-to-end network architectures for large-scale systems.
• Proven track record leading multi-team networking projects from design to turn-up.
• Strong ability to mentor engineers and drive design reviews.

Responsibilities

• Own the architecture of major areas of Lambda's network end to end — you make the design calls, you help build it, and you're connected to how they hold up in production
• Lead large networking projects that may span multiple teams, from design through build to turn-up, and drive them to completion
• Write the designs, RFCs and reviews other engineers build from, and hold the bar in design review for work across the team
• Be the deep technical escalation point for the hardest production problems — the packet path, the routing table, the vendor's firmware, the code
• Drive the automation of your domain, replacing manual operational work with software that holds up under scale
• Partner with hardware, platform and product teams to resolve technical questions that cross team boundaries
• Qualify and integrate new network hardware and software, and hold vendors to account on defects and roadmap
• Guide partner teams to automate and scale through robust software systems and services
• Guide partner teams build the right telemetry and automation to ensure our network health is observable and self healing
• Mentor senior and mid-level engineers, and raise the bar through design review, code review and hiring
• Contribute to the multi-year technical strategy for Lambda's network, and own the parts of it that fall in your area
• Work with internal and external customers to resolve network related issues
• Operate what you build. You'll take part in day 2 operations and the on-call rotation, because the fastest feedback loop between design and reality runs through the pager

Job description

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers. Our customers range from AI researchers to enterprises and hyperscalers. Lambda's mission is to make compute as ubiquitous as electricity and give everyone the power of superintelligence. One person, one GPU.

If you'd like to build the world's best AI cloud, join us.

*Note: This position requires presence in our Bellevue or San Francisco office location 4 days per week; Lambda’s designated work from home day is currently Tuesday.

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers. Our customers range from AI researchers to enterprises and hyperscalers. Lambda's mission is to make compute as ubiquitous as electricity and give everyone the power of superintelligence. One person, one GPU.

You will be joining a team of software, hardware and network engineers building one of the largest AI training and inference networks in the world. Lambda has 10x'd over the last three years and the network has to keep pace.

As a Senior Staff Network Engineer you'll have the opportunity to be across all aspects of the network, including industry leading backend, frontend, backbone and edge networks. You will lead the projects that design, build and scale it. You are the engineer the team routes its hardest problems to, and the one whose designs other engineers follow.

Our vision is bold and is not an incremental exercise. We will continually re-evaluate and reinvent our current fabric topology, routing design and the automation underneath all of it, while operating the existing network flawlessly for all customer workloads.

This role will report to our Senior Network Engineering leader and will work alongside an existing, highly capable team of network engineers.

What You’ll Do

• Own the architecture of major areas of Lambda's network end to end — you make the design calls, you help build it, and you're connected to how they hold up in production

• Lead large networking projects that may span multiple teams, from design through build to turn-up, and drive them to completion

• Write the designs, RFCs and reviews other engineers build from, and hold the bar in design review for work across the team

• Be the deep technical escalation point for the hardest production problems — the packet path, the routing table, the vendor's firmware, the code

• Mentor senior and mid-level engineers, and raise the bar through design review, code review and hiring

• Contribute to the multi-year technical strategy for Lambda's network, and own the parts of it that fall in your area

• Work with internal and external customers to resolve network related issues

• Operate what you build. You'll take part in day 2 operations and the on-call rotation, because the fastest feedback loop between design and reality runs through the pager

Nice to Have

• Have knowledge or experience maintaining Software Defined Networks (SDN)

• Experience automating network configuration

• Hands-on with HPC/AI networking: RoCEv2 and/or InfiniBand (Congestion Control, VLs, partitions), GPUDirect RDMA concepts.

• Experience with DWDM technologies and SD-WAN
