Required and preferred rules are kept separate and reflect the wording in the original posting.
About the Role
You will own production reliability for a Kubernetes-native control plane that provisions and runs GPU inference infrastructure. You will operate host-lifecycle workflows, investigate networking and serving failures, extend automated remediation, manage SLOs and incident response, and turn production lessons into improvements in controllers, automation, observability, and platform design.
Requirements
- Experience operating production provisioning or host-lifecycle pipelines at fleet scale.
- Deep experience owning reliability for large-scale distributed systems.
- Hands-on InfiniBand and RDMA troubleshooting experience.
- Familiarity with multi-tenant model serving, LoRA or adapter serving, and differentiated SLOs.
- Experience eliminating operational toil through self-built automation and tooling.
- Hands-on experience with Kubernetes controllers, CRDs, reconciliation loops, and node-level remediation systems.
- Knowledge of event-driven architectures, backpressure, circuit breaking, metrics, logs, and traces.
- Ability to write and ship production code for GPU infrastructure.
Responsibilities
- Operate the production provisioning state machine and host-lifecycle pipeline.
- Diagnose failed state transitions, GPU driver and CUDA validation issues, health-check failures, and decommissioning issues.
- Investigate InfiniBand, RDMA, GPU, hero-model, and LoRA-serving failures.
- Extend automated self-healing with detection and remediation plugins.
- Own SLOs and error budgets for provisioning and fleet health and lead incident response.
- Feed production topology, interconnect, and scheduling failures into platform requirements.
- Improve inference-stack performance, latency, throughput, and efficiency.
- Build observability tools and implement solutions for bottlenecks and instability.
- Lead cross-functional reliability planning and stakeholder management.
Benefits
- Startup equity.
- Health insurance.
