Job Description, Responsibilities & Requirements
About the Position
We are seeking a Principal SONiC Architect / Lead Developer to drive the next generation of open networking solutions for utility and telecom-grade environments. This role is pivotal in bridging the gap between high-level presales architecture and hands-on prototyping. You will architect open-source network operating system (NOS) solutions, estimate engineering efforts, build proof-of-concepts (PoCs), and guide clients through the transition from legacy transport networks to modern, SONiC-based architectures.
Responsibilities
- Architect open-source network operating system (NOS) solutions.
- Estimate engineering efforts and build proof-of-concepts (PoCs).
- Guide clients through the transition from legacy transport networks to modern, SONiC-based architectures.
- Drive the adaptation of SONiC across diverse silicon vendors.
- Design high-performance datacenter networks for modern Cloud Service Providers (CSPs).
- Configure and optimize SONiC QoS mechanisms.
- Implement advanced traffic management strategies.
- Align network fabric telemetry with GPU communication frameworks.
Requirements
Required Qualifications:
- Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, Network Engineering, or a related discipline.
- 8+ years in network software development, embedded systems, or advanced network architecture.
- Deep understanding of the SONiC architecture, including SAI, SwSS, and Syncd.
- Hands-on experience with Redis database architecture within SONiC.
- Experience containerizing network applications using Docker in a Linux environment.
- Strong background in transport networks, specifically MPLS-TP, label switching, LSPs, pseudo-wire emulation (PWE3), and transport tunnel provisioning.
- Expertise with IP/MPLS, Ethernet switching, VPNs, VLANs, and QoS configurations.
- Expertise in data center routing protocols and overlay architectures, specifically BGP-EVPN and VXLAN for scalable Leaf-Spine (Clos) topologies.
- Expertise with evaluating and architecting high-density, high-speed hardware platforms (400GbE / 800GbE) and understanding ASIC pipelines, buffer management, and hardware counters.
- Hands-on experience with high-performance network test and traffic validation tools (e.g., Keysight/Ixia, Spirent) to benchmark RoCEv2 traffic, packet loss, and latency under scale.
- Understanding of SCADA systems, utility communication constraints (latency, determinism), and energy IoT.
- Expert proficiency in C/C++ and Python for network application development and scripting.
- Deep familiarity with Linux networking, kernel-space vs. user-space interactions, and drivers.
- Proven experience in a presales, solutions architecture, or technical consulting role.
- Demonstrated ability to estimate engineering efforts, draft Statements of Work (SoWs), and deliver technical presentations to stakeholders and executives.
- Fluent English and good presentation skills.
Preferred Experience:
- Contributions to open-source networking projects (SONiC, FRR, ONF, etc.) are highly valued.
- Certifications: Cisco CCIE/CCNP SP/DC, Nokia SRA, MEF-CECP, Juniper JNCIE/JNCIP SP/DC.
- Knowledge of secure communication practices, including firewall configuration, IPS/IDS, and encryption.
- Hands-on with network simulation and configuration tools (e.g., Wireshark, GNS3, Cisco IOS, Junos).
