Networking Embedded Linux Engineer (Delhi)

Design Engineer PoE Switch Firmware (Embedded Linux)

Experience: 13 years

Location: New Delhi (Rohini , Prashant vihar)

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 recent 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)

23 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 .
