Sr. Staff Observability Engineer (GPU Cloud & Telemetry Platform)

Responsibilities

• End-to-End Observability Platform Ownership : Design and scale telemetry pipelines using:
• Grafana Alloy for metrics collection (Prometheus-compatible pipelines)
• Datadog Vector for high-throughput log ingestion and transformation
• Grafana Mimir for scalable time-series storage
• Grafana Loki for log aggregation and querying
• Strategic Roadmap : Define the multi-year vision for GPU infrastructure observability, transitioning from reactive monitoring to SLO-driven, predictive, and automated observability .
• High-Cardinality Telemetry Design : Optimize pipelines for GPU workloads characterized by:
• High-cardinality labels (GPU IDs, tenants, workloads)
• Burst-heavy workloads (ML training, inference spikes)
• Multi-tenant isolation requirements
• Architect low-latency, high-throughput pipelines capable of ingesting:
• GPU metrics (utilization, memory, thermals, MIG partitions)
• Kubernetes and container telemetry
• Distributed system logs and traces
• Build and optimize metric pipelines (Alloy → Mimir) ensuring:
• Efficient remote_write tuning
• Cost-effective retention strategies
• Horizontal scalability and compaction tuning
• Design log pipelines (Vector → Loki) with:
• Structured logging and enrichment
• Intelligent filtering/sampling
• Stream partitioning for high-ingest environments
• Establish deep observability into:
• GPU hardware (NVIDIA DCGM, MIG, NVLink, PCIe)
• Kubernetes GPU operators and scheduling behavior
• Network fabric (RDMA, InfiniBand, TCP performance)
• Define GPU-specific SLIs/SLOs such as:
• GPU utilization efficiency
• Job scheduling latency
• Cluster fragmentation
• Thermal and power anomalies
• Build rich Grafana dashboards for:
• Real-time GPU fleet health
• Tenant-level usage and billing insights
• Capacity planning and forecasting
• Standardize dashboard frameworks and reusable panels across teams
• Enable self-service observability for platform and ML engineering teams
• Drive adoption of SRE principles :
• SLIs, SLOs, error budgets tailored to GPU workloads
• Integrate observability into CI/CD and IaC pipelines (Terraform/Kubernetes) :
• Automated canary analysis
• Observability-driven rollbacks
• Build automation (Go/Python) for:
• Pipeline health monitoring
• Dynamic routing and scaling of telemetry workloads
• Develop tooling and practices for cross-layer correlation :
• GPU → Node → Kubernetes → Application → Network
• Lead deep RCA efforts for:
• GPU contention issues
• Performance degradation in ML workloads
• Telemetry pipeline backpressure/failures
• Enable "needle-in-a-haystack" debugging using unified logs + metrics
• Mentor engineers and lead design reviews for observability systems
• Act as a force multiplier across SRE, Infra, and ML platform teams
• Promote Observability-by-Design in all new GPU cluster deployments
• Drive adoption and contribution to:
• Grafana stack (Alloy, Mimir, Loki, Tempo)
• OpenTelemetry ecosystem
• Define build vs. buy decisions (Datadog vs OSS vs hybrid approaches)
• Optimize interoperability between Vector and OTEL pipelines
• Architect secure telemetry pipelines with:
• Encryption in transit and at rest
