Your Impact

You will be involved with a fast-paced work environment and responsible for end-to-end product development and production support. As a technical lead, you will be giving to the below activities:

Software Development & Integration:
  • Be responsible for the design, development, and deployment of software solutions leveraging SONiC to work with hardware infrastructure and platform-level components.
  • Develop and maintain platform adaptation layers for detailed integration between SONiC and underlying hardware (e.g., ASICs, BMC, optics modules, and other platform elements).
  • Collaborate with hardware teams to enable optimal hardware-software interactions and expose hardware capabilities—including optical diagnostics and SerDes tunables—through SONiC interfaces.
  • Write, review, and optimize code for critical system modules, drivers, and APIs supporting high-performance data planes and control planes.
  • Implement support for optical module management (e.g., DOM, power budgeting, module fault handling) and SerDes tuning/configuration via SAI or platform-specific SDKs.
  • Develop and maintain AN/LT (Auto-Negotiation and Link Training) logic integration across supported ASIC platforms for varied link bring-up.
System Architecture and Design
  • Define the technical architecture to integrate SONiC with platform infrastructure, ensuring scalability and high availability.
  • Design robust interfaces between SONiC and platform-specific management/control modules (e.g., telemetry, diagnostics, optics monitoring, and security components).
  • Lead efforts to optimize resource utilization, power efficiency, and operational stability of the network platform.
  • Architect solutions to support multiple optical form factors (QSFP-DD, OSFP, SFP-DD), breakout modes, and varying signaling rates (25G, 50G PAM4, 100G/lane) within SONiC's platform layer.
Leadership and Mentorship
  • Provide technical direction to the development team, mentoring junior and mid-level engineers on software engineering standard methodologies and advanced networking concepts.
  • Guide the team in debugging sophisticated link bring-up issues involving optics/SerDes/ANLT interactions across hardware and firmware layers.
  • Coordinate multi-functional activities between software, hardware, QA, and systems integration teams.
  • Drive code reviews, technical discussions, and issue resolution to ensure timely and quality work you're doing.
Collaboration and Stakeholder Engagement
  • Act as a key liaison with open-source SONiC communities, giving to upstream development and demonstrating community innovations.
  • Collaborate with product management and customers to understand use cases, capture requirements, and align work with business objectives—including emerging optics-related features such as CMIS support or link tuning APIs.
  • Own the evaluation and adoption of new tools, technologies, and methodologies to accelerate development and testing cycles, particularly in optics and link performance diagnostics.
Minimum Qualifications
  • Bachelors of Science
  • 12+ years of experience in software development within the networking or telecommunications industry
  • Expertise in C, C++, Python, Bash scripting
  • Software development experience with Linux-based platforms or other network operating systems such as SONiC
  • Experience with platform infrastructure such as ASIC drivers, BMC, and network OS development
  • Familiarity with optical transceivers (QSFP-DD, OSFP, SFP+, etc.), SerDes configuration, and AN/LT debugging across vendor SDKs
  • Experience working with virtualization, containerization, and orchestration frameworks such as Docker, Kubernetes, or similar
  • Experience leading teams or technical projects in a sophisticated development environment
Preferred Qualifications
  • Experience in CI/CD pipelines and automated testing frameworks
  • Experience with platform-level security requirements and compliance frameworks
  • Understanding of telemetry systems and software-defined networking (SDN)
  • Exposure to SONiC or experience working with the SONiC open-source community
  • Knowledge of hardware abstraction layers and SDKs from major networking silicon providers (Broadcom, Marvell, Mellanox/NVIDIA, etc.)
  • Experience with optical technologies including:
  • CMIS management interface for modern optical modules
  • SerDes tuning and signal integrity validation
  • Auto-negotiation and link training on PAM4-based interfaces
  • Breakout configurations and retimer behavior
  • Troubleshooting link flaps and optical faults across high-speed interface
