Senior Platform Software Engineer - Networking

Job Description:

Architect and build the system software behind high-performance ethernet switching networking platforms by owning design decisions end-to-end, optimizing for reliability and performance, and delivering capabilities that run at scale in real-world mission critical deployments.

Responsibilities:

- Drive system design and implementation for platform software across core networking subsystems, including chassis/line-card platform services, Ethernet interfaces, optics, and the underlying system infrastructure that ties hardware and software together.

- Own architecture and end-to-end delivery within JunOS or Junos Evolved - define interfaces between hardware and software and between various software components, evaluate design trade-offs, implement, and integrate across the networking software stack.

- Partner with system and solution test teams to set quality bars and build performance and reliability requirements, feedback to strong test strategy, and shorten debug/triage cycles.

- Work with support teams as the engineering owner - to perform root-cause analysis on production issues, drive fixes to closure, and continually harden the switching platform for best customer experience.

Education and Experience Required:

Bachelors degree in computer science, engineering, information systems, or related discipline. Masters desirable.

Knowledge and Skills:

- Deep experience with low-level systems domain: device drivers, board/system bring-up, and FreeBSD/Linux internals.

- Strong systems debugging skills - able to isolate cross-layer failures (hardware/firmware/OS), and reason about performance, concurrency, and resource bottlenecks.

- AI-first engineering mindset: comfortable using AI-assisted tools (e.g., coding copilots, LLM-based assistants) to accelerate design, implementation, and debugging - while validating outputs, writing tests, and protecting sensitive data.

- Requirement: consistently apply AI-assisted workflows across the system design lifecycle (problem framing - tradeoffs/interfaces - implementation - test/verification - production triage) to improve speed, quality, and reliability.

- Habit of documenting decisions and using lightweight design artifacts (problem statements, tradeoffs, interfaces) to align quickly and iterate with the team.

- Solid networking fundamentals (Ethernet; familiarity with switching concepts is a plus).

- Strong C/C++ engineering: clean API/interface design, OO design, data structures, and comfort with low-level/system debugging tooling.

- Working knowledge of hardware/firmware interfaces and integration points (PCIe, SPI, I2C, FPGA/CPLD) - able to translate datasheets into robust software abstractions and implementation.

- Bonus: prior experience shipping system software for networking products (platforms, routers/switches, or similar).
