The opportunity

Crusoe is on a mission to accelerate the abundance of energy and intelligence . As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads.

What you'll do

  • API Gateway: the front door to Crusoe Cloud. Every request to create, read,: or manage a cloud resource flows through the gateway this team owns. That means request routing, authentication and authorization enforcement, rate limiting and throttling, API versioning, and the tracing that makes a single call debuggable end to end.

  • Resource Management Layer: the abstraction between customer intent and physical infrastructure. Resource models and lifecycle state machines, reconciliation loops that drive declared state toward reality, capacity and placement coordination, and one consistent API surface behind every client.

  • Quota Management: the system of record for what every organization and project is entitled to consume. Our team built and owns the quota model for all Crusoe products and its enforcement path, along with the request and approval workflows that gate GPU, compute, storage, and networking capacity - a low-latency, strongly consistent, correctness-critical service sitting directly in the path of every resource creation.

  • Notifications: the platform-wide notification and eventing system that tells customers what is happening to their infrastructure - quota changes, capacity events, maintenance windows, billing thresholds, security alerts - across email, in-console, and webhook delivery. Event pipelines, templating, fan-out, delivery guarantees, deduplication, and per-user preference management at scale.

  • User Onboarding Flows: the path from sign-up to first successful workload. Identity and organization provisioning, invitations and role assignment, verification checks, and the self-serve flows that let a new customer go from account creation to running GPUs without a human in the loop.

  • Design, develop, and maintain scalable and reliable services that power our: cloud platform's user-facing experiences.

What they're looking for

  • Own and evolve the API gateway that fronts all Crusoe Cloud resource: management traffic - routing, authentication and authorization enforcement, rate limiting, versioning, and tenant isolation - without becoming a bottleneck for the teams shipping behind it.
  • Build the notification and eventing backbone that keeps customers informed: about the state of their infrastructure, with delivery guarantees and preference controls they can trust.
  • Evolve the quota and entitlement system into a first-class product surface:: self-serve quota requests, transparent limits, and enforcement that is both fast and correct under contention.
  • Reduce time-to-first-GPU for new customers by hardening and automating: onboarding, provisioning, and identity flows.
