Senior / Staff Software Engineer, Networking

Crusoe • San Francisco, CA

4h • $152,000 - $184,000

About The Position

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.

Requirements

• 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.

Nice To Haves

• 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).

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.

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
