Senior SDN Development Engineer (Management Plane)

Crusoe is on a mission to accelerate the abundance of energy and intelligence. As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads. When you join Crusoe, you join a team that is building the future, faster.

We're in the midst of the greatest industrial revolution of our time. The demand for AI compute is boundless, and power is a bottleneck. We're solving that — with an energy-first approach that makes AI infrastructure better for the world and faster for the people innovating with AI.

We're looking for problem-solving, opportunity-finding teammates with a sense of urgency, who believe in the scale of our ambition and thrive on a path not fully paved — people who want to grow their careers alongside a team of experts across energy, manufacturing, data center construction, and cloud services.

If you want to do the most meaningful work of your career, help our customers and partners advance their AI strategies, and be part of a high-performing team that believes in each other, come build with us at Crusoe.

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:

• Competitive compensation

• Restricted Stock Units

• Paid time off & paid holidays

• Comprehensive health, dental & vision insurance

• Employer contributions to HSA account

• Paid parental leave

• Paid life insurance, short-term and long-term disability

• Professional development & tuition reimbursement

• Mental health & wellness support

• Commuter benefits (parking & transit)

• Cell phone stipend

• 401(k) Retirement plan with company match up to 4% of salary

• Volunteer time off

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.
