About the role

Senior Backend Software Engineer on the Core Backend team within Cloud Customer Experience (CCX), focusing on building reliable, scalable foundational services behind Crusoe Cloud (API Gateway, Resource Management, Quota Management, Notifications, and Onboarding).

Responsibilities

  • Design, develop, and maintain scalable and reliable services that power our cloud platform's user-facing experiences.
  • 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.
  • Extend the resource management layer so new infrastructure offerings can be modeled, exposed, and reconciled without bespoke one-off plumbing each time.
  • Collaborate with cross-functional teams, like product and design, to evaluate tools, frameworks, and customer needs, creating innovative solutions that differentiate Crusoe Cloud.
  • Contribute to architectural decisions that support reliability and maintainability across the company.
  • Mentor engineers, enhance hiring practices, and contribute to building a strong, inclusive engineering culture.

Qualifications

  • 3+ years of software development experience, including programming with modern compiled languages such as Go, Rust, Java, or C++ (Go is primary).
  • Experience designing versioned public APIs (gRPC/protobuf, REST) and the SDK, CLI, or Terraform provider surfaces built on top of them.
  • Clear sense of API edge vs backing services (routing, authn/authz, rate limiting, quotas, input validation, graceful degradation).
  • Cloud expertise: design and scale fault-tolerant distributed systems and managed cloud services.
  • Strong relational database skills (PostgreSQL): schema design, transactions, isolation levels, locking, online migrations for correctness-critical data.
  • Experience with event-driven systems (Kafka, NATS, Pub/Sub or similar) and patterns like at-least-once delivery, idempotent consumers, retries, backoff, dead-letter handling.
  • Asynchronous workflows: long-running, resumable workflows and reconciliation loops (e.g., Temporal).
  • Proficiency with Docker, Kubernetes, Terraform, and CI/CD.
  • Observability: define SLOs, instrument with metrics/logs/traces, and troubleshoot in on-call contexts.
  • Collaboration, mentorship, and strong communication skills.
