Senior Backend Software Engineer, Cloud Management
Senior backend engineer building foundational Crusoe Cloud services, including the API gateway, resource management, quotas, notifications, and onboarding workflows. Requires distributed-systems experience, strong PostgreSQL skills, modern compiled-language expertise, and familiarity with reliable event-driven and asynchronous systems.
About the job
Responsibilities
- Design, develop, and maintain scalable, reliable services powering Crusoe Cloud’s user-facing experiences.
- Own and evolve the API gateway, including routing, authentication and authorization enforcement, rate limiting, API versioning, tracing, and tenant isolation.
- Build the notification and eventing backbone with reliable delivery and user preference controls.
- Evolve quota and entitlement systems, including self-service quota requests and fast, correct enforcement under contention.
- Improve customer time-to-first-GPU by hardening and automating onboarding, provisioning, and identity flows.
- Extend resource management models, lifecycle state machines, reconciliation loops, and infrastructure offerings.
- Contribute to architectural decisions supporting reliability and maintainability.
- Collaborate with product, design, and cross-functional teams to evaluate tools, frameworks, and customer needs.
- Mentor engineers, improve hiring practices, and contribute to an inclusive engineering culture.
Requirements
- 3+ years of software development experience.
- Experience programming with modern compiled languages such as Go, Rust, Java, or C++; Go is used primarily by the team.
- Experience designing versioned public APIs using gRPC/protobuf or REST, plus related SDK, CLI, or Terraform provider surfaces.
- Knowledge of API gateway and edge concerns, including routing, authentication, authorization, rate limiting, throttling, quota checks, validation, and graceful degradation.
- Experience designing and scaling fault-tolerant distributed systems and managed cloud services.
- Strong PostgreSQL skills, including schema design, transactions, isolation levels, locking, and safe online migrations.
- Experience with message queues or streaming systems such as Kafka, NATS, or Pub/Sub.
- Knowledge of reliable event-driven patterns, including at-least-once delivery, idempotent consumers, retries, backoff, and dead-letter handling.
- Experience building long-running, resumable workflows and reconciliation loops, using state machines, control loops, or workflow engines such as Temporal.
- Strong fundamentals in data structures, algorithms, microservices, and infrastructure tooling.
- Experience with Docker, Kubernetes, Terraform, and CI/CD systems.
- Experience defining SLOs, instrumenting services with metrics, logs, and traces, and debugging production systems while on call.
- Strong cross-functional collaboration, communication, and mentorship skills.
Nice-to-haves
- Experience building infrastructure tooling.
- Experience with cloud customer experience platforms, resource management, quotas, entitlements, notifications, or onboarding systems.
- Experience improving engineering hiring and onboarding processes.
