Strong employer brand and mid-level range increase competition, but niche embedded firmware skills moderate density.
Embedded firmware and hardware-interface expertise is industry-specific and not easily transferable across domains.
Explicit 3–5 years plus mandatory embedded, driver, RTOS, and hardware-interface skills create strict filters.
Design, implement, and test firmware for next-generation Optical line system products such as ROADM, EDFA, and Raman used in optical network deployments.
Develop and maintain Firmware Requirement and Design documents, collaborate cross-functionally for integration, and support manufacturing processes.
Debug and resolve customer issues, participate in design reviews, and contribute to improving firmware development processes.
3 to 5 years of embedded software development experience in a multithreaded real-time environment.
BE/BTech or ME/MTech in Computer Science, Electronics and Communications Engineering, or related field.
Strong C/C++ programming skills, system understanding, debugging proficiency, and experience with Linux or RTOS device driver development.
Hands-on experience in hardware interfaces (I²C, SPI, Ethernet, PCIe), hardware bring-up, Uboot bootloader, and use of test equipment like JTAG debuggers.
Experience working with optical domain firmware products and understanding of optical network hardware integration.
Ability to work collaboratively with geographically dispersed teams and contribute to design and architectural decisions.
Familiarity with embedded Linux, RTOS environments (e.g., FreeRTOS, ThreadX), and comfortable with cross-functional collaboration including hardware, FPGA, software, and manufacturing teams.
