About this Senior Software Development Engineer role at Lambda
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.
What You’ll Do
Design, build, and operate the software that automates Lambda's network lifecycle, from data center build-out and device provisioning through day-2 operations
Build provisioning and zero-touch deployment systems that take network devices for new GPU clusters from racked to production-ready with minimal manual work
Develop pipelines that generate, validate, and deploy network configuration as code, with automated testing, staged rollouts, and safe rollback
Build capacity planning tools that combine inventory, topology, and utilization data to forecast port, bandwidth, optics, and IP address needs as Lambda's footprint grows
Keep intended and live network state in sync by integrating automation with Lambda's source-of-truth, inventory, and IPAM systems
Create APIs, services, and CLIs that network engineers and other internal teams use to request, change, and audit network resources
Instrument the systems you own with metrics, logging, and alerting, and use that data to improve their reliability and speed
Partner with Network Engineering, Data Center Operations, and platform teams to turn manual runbooks into reliable, self-service automation
Participate in the on-call rotation for the automation systems and tooling your team owns
You
Have 6+ years of professional software engineering experience building and operating production systems
Write production-quality code, with deep expertise in multiple languages
Have built automation or infrastructure tooling used by other engineers, such as provisioning systems, deployment pipelines, workflow engines, or internal APIs
Have a solid grasp of distributed systems design, including API design, data modeling, idempotency, and handling partial failures
Follow strong engineering practices: code review, automated testing, CI/CD, and git-based workflows
Are comfortable on the Linux command line and understand core networking concepts such as TCP/IP, DNS, DHCP, VLANs, and IP routing
Have led technical projects end to end, from design doc through production rollout, and mentored other engineers along the way
Communicate clearly with software engineers, network engineers, and operations teams, and can turn operational pain points into software requirements
Nice to Have
Experience in the networking domain, such as designing or operating data center networks (Clos/spine-leaf fabrics, BGP, EVPN/VXLAN, ECMP)
Experience automating network devices from vendors such as Arista, Juniper, Cisco, or NVIDIA (Cumulus/SONiC) through their APIs, NETCONF/gNMI, or Jinja templating
Familiarity with network automation tools and libraries such as Ansible, Nornir, Netmiko, NAPALM, or Terraform
Experience building on network source-of-truth, DCIM, or IPAM systems
Experience building capacity planning or forecasting tools, or working with large volumes of time-series telemetry
Familiarity with HPC/AI networking, such as InfiniBand or RoCEv2, at GPU cluster scale
Experience running services on Kubernetes
Understanding of data center power, space, and cooling constraints and how they shape build-out plans
Salary Range Information
The annual salary range for this position has been set based on market data and other factors. However, a salary higher or lower than this range may be appropriate for a candidate whose qualifications differ meaningfully from those listed in the job description.
