Job description

Designation- Platform Software Engineer (Networking Systems)

Junior role- 1-3 years of exp

Sr Role- 4-10 yrs of exp

JD- Platform Software Engineer (Networking Systems)

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:

• Bachelor’s degree in computer science, engineering, information systems, or related discipline. Master’s 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).
