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.

You will be joining a team of highly capable software, hardware and network engineers building one of the largest AI training and inference networks in the world. You'll collaborate with people across Lambda to deliver novel and inventive software solutions that meet the highest standards for safety, security, availability and performance - at the lowest possible cost for our customers. You will experience an inclusive and inventive culture that welcomes bold ideas and empowers you to own them from concept to production.

Our vision is bold and is not an incremental exercise. We will continually re-evaluate and reinvent the software services required to build networks at massive scale and the automation underneath all of it, while operating the existing network flawlessly for all customer workloads.

This role will report to the VP of Cloud and AI Networking, working alongside a highly capable and passionate team of engineers.

If you'd like to join a great team of customer obsessed engineers building the world's best AI cloud, come join us.

What You’ll Do

• Own the multi-year technical strategy for Lambda's networking software roadmap covering tools, software and services supporting backend GPU fabric, frontend networks, backbone, edge and everything in between.

• Set the technical direction and standards other engineers design, build and operate against.

• Own high-level technical relationships with enterprise customers, guiding mission-critical projects

• Influence across teams applying high quality technical judgment

• Resolve any technical ambiguity that spans organisational boundaries — between network, hardware, platform and product teams

• Go deep when the hardest problems demand it — into the code, the network, the customer use case. You are hands-on.

• Drive the technical work end to end: shape the vision, define high- and low-level design, then work alongside the teams delivering it

• Raise the bar of the engineers around you through mentorship, design review and hiring

• 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 our customer runs through the pager

• Serve as the senior technical voice with our largest customers on mission-critical projects, and carry what you learn there back into Lambda's roadmap

• Identify new opportunities to delight our customers, like novel new ways to improve availability or performance or even developing new products.
