Senior Cloud Infrastructure Engineer, Cloud Foundations

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 San Francisco/San Jose/Bellevue office location 4 days per week; Lambda’s designated work from home day is currently Tuesday.

Cloud Foundations manages the account, access, and network foundation that Lambda's cloud infrastructure runs on, implementing governance and access controls in line with company policies. In practice that means AWS accounts and IAM, the VPC and transit network structure, DNS, and the Terraform execution platform that every change flows through.

This is a new team, and this role helps define it. Working closely with Security, GRC, IT, and the engineering teams that consume the foundation, this position turns policy into working controls and paved paths, so that hundreds of engineers can safely self-serve instead of filing requests.

What You’ll Do

Own and evolve the IaC execution platform (Terraform, Atlantis): how infrastructure changes are proposed, reviewed, and applied across the company

Design and operate Lambda's cloud account, access, and IAM structure: organizational hierarchy, provisioning, and permission models

Own the cloud network foundation: VPCs, Transit Gateway, and DNS, including the patterns other teams build on

Drive AWS cloud governance: tagging standards, compliance guardrails, and cost visibility and accountability

Implement least-privilege access and compliance automation in line with company requirements and policies, replacing manual access and provisioning work with self-service

Help shape how this new team operates: its scope, priorities, and service boundaries

Participate in an on-call rotation and keep the systems you own well-documented, reliable, and observable

Who You Are

6+ years of experience in cloud infrastructure, cloud platform, or cloud security engineering, or a closely related discipline

Deep experience managing AWS at scale: multi-account organizations, IAM and permission boundaries, SCPs, and resource organization

Strong foundation in infrastructure-as-code (Terraform) and the tooling around it: modules, state management, and automated plan/apply workflows

Solid cloud networking fundamentals: VPC design, transit and hybrid connectivity, DNS, and edge/CDN configuration

Comfortable writing the automation and tooling that runs the foundation (Go and/or Python), and treating it as a product: real users, real quality standards, and things that actually get adopted

Use AI tools as a natural part of how you work, and hold their output to the same bar as your own: you review it, verify it, and own what ships

Build for the many, not for one team or one use case

Comfortable with ambiguity and clarifying ownership

Distill the right problem out of the noise: ask the why behind the why

Own what you build past the point it ships: monitor it, measure whether it actually helped, and act on what you learn

Sweat the details and aren't satisfied until things run smoothly

Nice to Have

Experience building agentic workflows that automate meaningful parts of infrastructure operations or governance

Experience implementing controls for a compliance program (SOC 2, ISO 27001) without turning it into manual toil

Cloud cost management and FinOps experience

Hands-on experience with Azure, GCP, or OCI alongside AWS
