Networking Embedded Linux Engineer

Design Engineer – PoE Switch Firmware (Embedded Linux)

Experience: 2–3 years

Location: New Delhi

About the Role

We're looking for a Design Engineer to develop and maintain embedded Linux firmware for our PoE (Power over Ethernet) switch product line. You'll work across the stack — from bootloader and kernel driver bring-up to power management logic and network-facing management interfaces — collaborating closely with hardware and validation teams to bring new switch platforms from prototype to production.

Key Responsibilities

· Develop and maintain embedded Linux firmware for managed PoE switch platforms (802.3af/at/bt)

· Implement and validate PoE power-budget, port-priority, and classification logic in coordination with PSE controller ICs.

· Write and debug kernel-level drivers (I2C, SPI, GPIO, UART) for switch-management peripherals

· Bring up new hardware revisions, diagnosing boot-time and flash-initialization failures using JTAG, serial console, and logic analyzers

· Build and extend SNMP/CLI-based management and health-monitoring features (port status, power draw, temperature)

· Support PCB bring-up and EVT/DVT testing, isolating firmware-vs-hardware faults

· Document firmware architecture, register maps, and bring-up procedures

· Participate in code reviews and contribute to CI-based build/test pipelines

Required Qualifications

· B.Tech/B.E. in Electronics or Computer Engineering (or equivalent experience)

· 2–3 years of hands-on embedded Linux firmware development

· Working knowledge of PoE standards (IEEE 802.3af/at/bt) and PSE/PD controller ICs

· Strong C programming skills; comfortable with kernel module and driver development

· Experience with I2C, SPI, GPIO, UART, and MDIO/MDC interfaces

· Familiarity with U-Boot, device tree, and cross-compilation toolchains

· Practical debugging skills using JTAG, oscilloscopes, and logic analyzers

· Proficiency with Git and Linux-based development workflows

Preferred Qualifications

· Exposure to Ethernet switch ASIC/PHY bring-up, VLAN/QoS configuration

· Experience with SNMP MIB integration or network management protocols

· Familiarity with Yocto/Buildroot-based BSP development

· Scripting experience in Python or Bash for test automation

· Prior work on networking or power-delivery hardware products
