Macrohire; Bengaluru; On-site; INR 1,800,000 - 3,000,000; Full time

Job summary

Macrohire Bengaluru seeks an experienced senior network systems engineer to drive system design and implementation for platform software across core networking subsystems, including chassis/line-card services, Ethernet interfaces, optics, and the hardware-software integration.

You will own architecture within JunOS or Junos Evolved, define interfaces, and collaborate with test and support teams to ensure quality and reliability while translating datasheets into robust software across complex

Qualifications

• Deep experience with low-level systems domain: device drivers, board/system bring-up, and FreeBSD/Linux internals.
• Strong systems debugging skills - isolate cross-layer failures and reason about performance.
• AI-first engineering mindset: using AI-assisted tools to accelerate design, while validating outputs and writing tests.
• Apply AI-assisted workflows across the system design lifecycle to improve speed and reliability.
• Document decisions with lightweight design artifacts for quick alignment.
• Solid networking fundamentals (Ethernet) and familiarity with switching concepts.

Responsibilities

• Drive system design and implementation for platform software across core networking subsystems.
• Own architecture and end-to-end delivery within JunOS or Junos Evolved - define interfaces between hardware and software.
• Partner with test teams to set quality bars and build performance and reliability requirements.
• Work with support teams to perform root-cause analysis on production issues and harden the switching platform.

Job description

Exp- 7-15 yrs

• 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.

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).
