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.

[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.

Investigate and resolve complex cross‑layer network issues, including packet flow, protocol interactions, and performance bottlenecks.

[Requirements]

Strong understanding of the OSI 7‑layer model and cross-layer interactions.

Experience with network‑related programming or systems involving packet processing or protocol handling.

Proficient in both common and advanced network protocols (e.g., Ethernet, ARP, IP, TCP/UDP, DHCP, DNS, HTTP/S, TLS, QUIC, VPN protocols).

Ability to quickly evaluate and build PoCs to validate concepts and designs.

Proficiency in at least one network‑related programming language, such as C/C++, Go, Rust, or Python.

Strong analytical thinking, clear communication skills, and the ability to work independently on complex technical challenges.

[Nice-to-Have]

Hands-on experience with next‑generation networking technologies such as IPv6, NAT64, MAP‑E/DS‑Lite, or CGNAT.

Familiarity with DPI, SNI matching, traffic fingerprinting, or related technologies.

Knowledge of kernel‑level networking or netlink APIs.
