Job description
Structured overview of role & requirements
About This Role
- Design and implement IOS-XR forwarding features across QoS, mirroring, OAM, L2/L3 protocols, and related mechanisms.
- Program and optimize NPU data-plane processing; debug defects using logs, core dumps, and packet traces, including hardware/software interactions.
- Tune forwarding code for service-provider latency and throughput requirements; use AI-assisted tools for coding, testing, and analysis.
Minimum Requirements
- Work Experience Required: 5–10 years in embedded software development for networking products; the title lists 4–9 years, so the JD has a discrepancy.
- BS/MS in Computer Science, Electrical Engineering, or a related field.
- Strong Embedded C and Python skills; experience with CI/CD, Git, and code review processes.
- Material networking fit: NPU data-plane architecture and packet processing, plus implementation experience in relevant L2/L3 forwarding protocols or features; service-provider router deployment knowledge is also required.
Ideal Candidate Profile
- Has built embedded forwarding software for carrier-grade routers and understands service-provider core or peering environments.
- Can translate protocol requirements into efficient NPU pipeline, table, and packet-processing behavior, and isolate hardware-versus-software failures.
- IOS-XR or a similar carrier-grade network OS, Silicon One/Broadcom/ezChip NPU exposure, and AI-assisted engineering tools are useful shortlist signals.
