Software Engineer, Backend (Security)

About Base

Base is America’s next-generation power company. We’re rebuilding the foundation of modern civilization–electricity–by deploying a vast network of distributed batteries that is transforming today’s fragile, centralized grid into a resilient and abundant system. We are engineers, operators, and creatives solving some of the most complex, interdisciplinary challenges of our time.

About the Role

We are seeking Software Engineers to build the Identity Provider and Authorization platform that decides who — and what — can access Base's systems.

Base runs on a growing mix of internal apps, cloud infrastructure, and machines that all need to authenticate and authorize safely: employees signing into AWS and GCP, services talking to each other, and devices proving their own identity in the field. This role will own the platform layer that turns fragmented, ad hoc access into a single, auditable identity system.

You will design the core primitives for identity and access: workforce SSO, cloud federation, entitlements-as-code, and workload identity backed by a governed PKI. The ideal candidate is a hands-on engineer who takes security-critical systems seriously, moves fast without cutting corners on least privilege, and can turn a still-forming scope into durable infrastructure
