Senior Software Development Engineer

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

You will design, build, and operate the software that automates Lambda's network lifecycle, from data center build-out and device provisioning through day-2 operations.

Responsibilities:

• Design, build, and operate the software that automates Lambda's network lifecycle
• 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

Requirements:

• 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
• 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
• 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

Nice to Have:

• Experience in the networking domain
• Experience automating network devices from vendors such as Arista, Juniper, Cisco, or NVIDIA
• Familiarity with network automation tools and libraries
• Experience building on network source-of-truth, DCIM, or IPAM systems
• Experience building capacity planning or forecasting tools
• Familiarity with HPC/AI networking
• Experience running services on Kubernetes
• Understanding of data center power, space, and cooling constraints

Benefits:

• Generous cash & equity compensation
• Health, dental, and vision coverage for you and your dependents
• Wellness and commuter stipends for select roles
• 401k Plan with 2% company match (USA employees)
• Flexible paid time off plan
