Senior / Staff Software Engineer, Networking at Crusoe

Crusoe's mission is to accelerate the abundance of energy and intelligence. We’re crafting the engine that powers a world where people can create ambitiously with AI — without sacrificing scale, speed, or sustainability. Be a part of the AI revolution with sustainable technology at Crusoe. Here, you'll drive meaningful innovation, make a tangible impact, and join a team that’s setting the pace for responsible, transformative cloud infrastructure. About the Role: We are looking for a Software Engineer who views the network as a distributed system. In this role, you will build the software layer responsible for the "Closed-Loop Automation" of our global fabric. You will be building the systems that ingest billions of telemetry events and programmatically steer traffic in real-time to optimize performance and availability. What You’ll Be Working On: - 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. What You’ll Bring to the Team: - Systems Programming: Professional experience in Go (Golang) or C++. We prioritize memory safety and concurrency. - Network Fundamentals: 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. - Modern Observability: Hands-on experience building or extending TSDBs (Prometheus, VictoriaMetrics, or InfluxDB) and using OpenTelemetry. - Cloud-Native Tools: Experience deploying management microservices via Kubernetes, using Kafka or RabbitMQ for message bus architectures. Bonus Points: - 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). Benefits: - Industry competitive pay - Restricted Stock Units in a fast growing, well-funded technology company - Health insurance package options that include HDHP and PPO, vision, and dental for you and your dependents - Employer contributions to HSA accounts - Paid Parental Leave - Paid life insurance, short-term and long-term disability - Teladoc - 401(k) with a 100% match up to 4% of salary - Generous paid time off and holiday schedule - Cell phone reimbursement - Tuition reimbursement - Subscription to the Calm app - MetLife Legal - Company paid commuter benefit; $300 per month Compensation: Compensation will be paid in the range of $152,000 - $184,000 per year + Bonus.
