Job SummaryLynk is developing cellular-based space payloads and seeks engineers with expertise and experience designing and developing custom software-defined radio (SDR) platforms. Aspects of the position require an understanding of FPGA hardware, firmware, digital signal processing, and algorithms for SDR-based satellite communication.
As a Senior FPGA Engineer, you will support the development of custom radio platforms for the primary (cellular service link) and secondary (TT&C / feeder link) communication links. The platform will initially be tested in a lab environment, then on the payload prototype in a lab environment that simulates orbit operations, and finally in space. The Senior FPGA Engineer will also be responsible for designing and implementing methods for ensuring successful testing, verification, and validation.
Core ResponsibilitiesAs a Senior FPGA Engineer, your core responsibilities are as follows:
- Design high-speed FPGA RTL designs for satellite communication systems
- Understand the hardware-based requirements, e.g., FPGA size, speed, clock stability, I/O interfaces, sample rates, dynamic range, and radio chip architecture.
- Design and evaluate digital signal processing (DSP) algorithms for FPGA.
- Update or create host interface software to interact with FPGAs.
- Implement device driver software in C, C++, or other languages for a Linux environment.
- Test and validate hardware blocks both in simulation and on target.
- Develop and maintain documentation and ICDs for in-house IP blocks and other related components.
Qualifications- A Bachelor's degree (or higher) in Electrical Engineering, Computer Engineering, or related field.
- At least three years of recent experience working with Xilinx/Altera FPGAs.
- Experience with high-speed interfaces such as JESD204C and PCI Express.
- Experience with RFICs such as Analog Devices AD9371.
- Experience with Linux device drivers.
- Ability to create test benches for system validation and benchmarking.
- Experience using lab equipment for testing and validation.
- Experience with evaluating SDR platforms and specifications.
- Experience with SoC designs such as Xilinx Zynq and Xilinx Versal (preferably with AI Engine) is a plus.
- Knowledge of PHY and MAC layers of cellular standards (e.g., GSM, LTE, 5G) is a plus.
