Our Optical Line System team is searching for an experienced embedded and real-time software developer for our leading-edge optical line system product line. Our team is responsible for developing carrier grade embedded software which follows modular and reusable design principles. The candidate is required to fully understand line system software architecture and its real time operating system and be able to work independently developing optical control and shelf controller interface software for new products as well as sustaining legacy products. To achieve this goal, the candidate is required to work closely in a multi-disciplinary environment and be able to interact with optical, hardware and software engineers to drive closure of any design and development requirements and issues.
Responsibilities- Work closely with hardware/FPGA engineers to understand HW control architecture including CPU architecture, memory access and control of various peripherals. Be able to independently develop firmware that supports the designed hardware, e.g. driving DACs, reading ADCs and control flash devices through low level device interfaces or FPGA interfaces.
- Work closely with optical engineers to define optical control requirements and develop control algorithms. Implement the control algorithms on top of Linux and FreeRTOS operating systems.
- Work on software interface layer that communicates with system controller on a different card through gRPC interface over Ethernet.
- Provide to management team accurate design estimates for planning purposes.
- Follow development processes to ensure delivery of quality products on time.
- Flexible and adapt to changing tasks when needed.
You have:
- Bachelor or higher degree in Computer Engineering/Electrical Engineering, or equivalent education.
- Minimum 5 years of industry experience in real-time programming using C/C++ in embedded Linux and/or RTOS environments
- Solid experience with low-level device interfaces, including UART, SPI, and I2C.
- Proficient in using lab equipment, such as oscilloscopes and power meters.
- Strong understanding of SOC controller/processor architecture, Linux kernel, and real-time OS operations.
- Experience with CMAKE build system
- Working knowledge in gRPC and protobuf design and implementation
- Proven ability to quickly grasp new technical concepts.
- Excellent written and verbal communication and presentation skills.
It would be nice if you also had:
- Experience with optical networking communication systems, particularly optical transceivers or fiber optics modules.
- Familiarity with optical technologies and components such as EDFAs, WSS, OCMs, and OTDR.
- Experience with Xilinx Zynq/Ultrascale.
- Understanding of digital signal processing principles or PID control algorithms.
- Knowledge of Petalinux and its build environment.
