Job Summary:
Crusoe is an AI infrastructure company focused on accelerating the abundance of energy and intelligence. They are seeking a Senior SDN Development Engineer to build the software layer for Closed-Loop Automation of their global fabric, optimizing performance and availability through real-time traffic management and telemetry data processing.
Responsibilities:
• Build Telemetry Pipelines: Design and implement high-throughput data ingestion services using gNMI, gRPC, and P4-Runtime.
• Develop Traffic Engineering (TE) Logic: Write the algorithms and controllers that interface with Segment Routing (SRv6/SR-MPLS) to dynamically reroute traffic based on real-time link health.
• Data Modeling: Architect and maintain structured data models using YANG, ensuring a "Single Source of Truth" for network state.
• API Ecosystem: Develop internal RESTful and gRPC APIs that allow other services to query network topology and performance metrics programmatically.
• Performance at Scale: Optimize Go/Python services to handle high-cardinality time-series data without introducing latency into the management loop.
Qualifications:
Required:
• Professional experience in Go (Golang) or C++
• A deep understanding of the TCP/IP stack, specifically how the Management Plane interacts with the Control Plane (BGP, IS-IS) and the Forwarding Plane
• Hands-on experience building or extending TSDBs (Prometheus, VictoriaMetrics, or InfluxDB) and using OpenTelemetry
• Experience deploying management microservices via Kubernetes, using Kafka or RabbitMQ for message bus architectures
Preferred:
• Contributions to open-source SDN projects (e.g., SONiC, ONOS, Stratum, or P4)
• Experience with eBPF for deep packet inspection and kernel-level observability
• Familiarity with Network Verification tools (e.g., Batfish or Forward Networks)
