Senior / Staff Software Engineer, Networking

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. Restricted Stock Units are included in all offers. Compensation will be determined based on the applicant's knowledge, education, experience, and abilities, as well as internal equity and alignment with market data.
