Software Engineer

Overview:

We are seeking a highly motivated and experienced Software Engineer with deep

expertise in SONiC (Software for Open Networking in the Cloud), L2/L3 networking, and

SDN (Software-Defined Networking) control-plane integration. In this role, you will be a

key contributor to the design, development, and optimization of SONiC's northbound

interfaces using gNMI/gNOI and OpenConfig data models, enabling seamless

interoperability with SDN controllers.

You will work at the intersection of hardware and software, focusing on SONiC's

management and control frameworks, Redis database pipelines, and containerized

services. This is a hands-on engineering role for individuals passionate about open

networking, programmable network infrastructure, and disaggregated NOS design.

Multiple positions are open across seniority levels, including Senior Engineer and

Principal Engineer.

Key Responsibilities:

Design, implement, and integrate gNMI/gNOI-based northbound interfaces in

SONiC using OpenConfig YANG models, enabling SDN controller

interoperability.

Extend and customize SONiC NOS for advanced Ethernet and optical circuit

switch(OCS) platforms, ensuring scalability and operational consistency.

Develop and maintain SONiC Redis database schemas and synchronization

logic across management and control components.

Build, containerize, and orchestrate SONiC services using Docker, ensuring

modularity, maintainability, and performance.

Develop automated tests, validation scripts, and simulation frameworks for

SONiC platform bring-up and API verification.

Collaborate with cross-functional teams including hardware, ASIC, and SDN

controller teams to deliver fully integrated SONiC-based networking solutions.

Required Skills & Qualifications:

Bachelor's or Master's degree in Computer Science, Electrical Engineering, or a

related field.

Strong proficiency in C/C++ for system and infrastructure programming and

Python for automation and testing.

Deep understanding of SONiC NOS architecture, including its management

framework and Redis-based database design.

Experience implementing gNMI/gNOI services and working with OpenConfig

YANG models for configuration, telemetry, and RPC interfaces.

Solid grasp of Linux kernel networking, user-space networking services, and

container-based system design.

Hands-on experience with Docker, debugging containerized environments, and

optimizing service performance.

Excellent problem-solving, debugging, and cross-layer system analysis skills.

Proficiency in Mandarin and English for eƯ ective collaboration with global

hardware and software teams.

Preferred Qualifications:

Strong understanding of SONiC database architecture with Redis and

OpenConfig Yang model

Strong understanding of Layer 2/Layer 3 networking protocols.

Familiarity with CI/CD tools such as Jenkins, GitLab CI, or Gitea.

Knowledge of AI/ML data center architectures and SDN paradigms.

Why Join Us

Work on cutting-edge networking technologies that power hyperscale data

centres and cloud infrastructure.

Collaborate with a world-class team of engineers and SONiC NOS team.

Opportunity to shape the future of disaggregated networking and software

defined infrastructure.
