Job description

Talent Acquisition Professional | Equality, Diversity & Inclusion Advocate | Relationship Builder, Collaborator & Mentor

Dear Professionals,

Greetings of the day…!!!

We are seeking an experienced and highly-skilled Senior Software Engineer to join our team, focusing on the development and enhancement of high-performance L2/L3 network dataplane features. The ideal candidate will have deep expertise in the C language, low-level system programming, and a strong background working with networking silicon, particularly Broadcom chips. This role involves close collaboration with external partners, including the Cisco team, to contribute to product design and delivery.

Key Responsibilities

Design, develop, and test high-performance, robust software for network switching and routing products using the C language.
Develop and maintain features within the L2 (Data Link Layer) and L3 (Network Layer) dataplane, ensuring optimal throughput and low latency.
Implement and optimize control plane and forwarding plane functionalities related to MPLS (Multiprotocol Label Switching) and QoS (Quality of Service).
Work extensively with networking silicon, specifically developing, integrating, and debugging SDKs (Software Development Kits) and drivers for Broadcom platforms.
Actively participate in the product design process, providing technical expertise and contributing to architectural decisions in collaboration with internal and external teams (e.g., Cisco).
Apply advanced C programming techniques for low-level systems, including IPC (Inter-Process Communication), multi-threading, and efficient memory management.
Develop robust, efficient implementations of core data structures like Stacks/Queues and Linked Lists for network processing pipelines.

Required Qualifications

5-7 years of hands-on professional experience in C language development, specifically within L2/L3 networking or embedded systems.
Proven experience in Broadcom networking silicon architecture, SDK, and driver development is essential.
Demonstrable expertise in implementing networking protocols, specifically MPLS and QoS.
Strong theoretical and practical knowledge of networking fundamentals (TCP/IP stack, Ethernet, Routing protocols).
Deep, hands‑on expertise in the following C programming areas:
- IPC and multi‑threading for concurrent and high‑throughput applications.
- System‑level memory management and optimization.
- Implementation and use of core data structures (Stacks/Queues, Linked Lists).
Ability to quickly understand complex product designs and architectural documentation and contribute effectively to the development lifecycle alongside partner teams (e.g., Cisco).
Excellent problem‑solving, debugging, and collaboration skills.
