About the role
We are looking for a Senior Network Expert / Engineer with deep expertise in network protocols and architecture. In this role, you will design and evaluate network architectures from a holistic perspective while diving into the technical details of each layer in the OSI model to ensure that every solution is practical and reliable.
If you are passionate about network protocols, packet behavior, and cross-layer interactions—and can leverage your experience and technical insight to guide architectural direction—this will be an excellent opportunity for you to join our team.
Responsibilities
[Key Responsibilities]
•
Design, evaluate, and optimize overall network architecture, protocol workflows, and system integration approaches.
•
Research and analyze various network protocols, including standard, advanced, and emerging technologies.
•
Perform in-depth analysis of OSI Layer 2–7 behaviors and assess their impact on system design.
•
Build rapid Proof‑of‑Concept (PoC) implementations to validate network features, protocol behaviors, or new architectures.
•
Collaborate with cross-functional technical teams to provide recommendations and support network‑related design decisions.
•
