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:

• 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.

• 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.

• 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.

• 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.
