About The Job

FPGA's are critical to Siglab's commercial and residential broadband products. Work on RTL implementing state-of-the-art DSP algorithms which are deployed live to thousands of customer products. Develop on large ASIC emulator platforms. Use large build clusters to simulate and synthesize dozens of FPGA's simultaneously. Break conventional workflow and develop in a massively parallel and pipelined toolchain. Use and improve custom in-house FPGA build tools. Be an early part of a team that is changing the world. This is not a boring desk job. Excited applicants only, please.
