Lambda Senior Software Development Engineer at Lambda building automation software for network lifecycle and GPU cluster provisioning. Develop APIs, services, and tools to streamline network operations.
Responsibilities
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
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
