Job Type : W2 Contract

Background:

The Optical Communications Technology Group develops advanced laser communications technology for many applications. Research in optical switching and optical logic supports the development of future ultra-high-speed, all-optical routing. Research in superconducting, single-photon-counting detectors, novel modulation formats, and coding supports the development of future high-data-rate, interplanetary laser communications links. These technologies support the most sensitive optical communications links ever developed, enabling communication of several bits per detected photon across vast distances.

Must Have:

1. Proficient in Verilog, SystemVerilog, VHDL and C.
2. Ability to take an FPGA from concept to a device that meets all functional and timing requirements. This would also include generating system level test benches to verify FPGA performance, functionality and error recovery using Mentor Questa Logic Simulator.
3. Experience with the Zynq Ultrascale+ RFSoC platform.
4. Experience coding across multiple clock domains.
5. Experience coding triple-mode redundancy for radiation resistance.
6. Familiarity with the digital processing architecture for lasercom waveform standards.
7. Candidate must have demonstrated knowledge of and delivered products involving:
1. the Xilinx Virtex 5 SIRF FPGA;
2. Xilinx ISE 13.2 with SIRF Overlay;
3. Synopsys Synplicity targeting the Virtex 5 SIRF;
4. Code design for radiation-hardened operation of the Xilinx Virtex 5 SIRF;
5. Radiation-hardened CPUs;
6. Analog to digital converters (ADCs) and digital to analog converters (DACs);
7. SPI, I2C, SpaceWire, and Ethernet protocols;
8. Forward error correction, including Reed-Solomon and DVB-S2;
9. CoaXPress and CameraLink camera interfaces;
10. Differential phase-shift keying (DPSK) and pulse position modulation (PPM) optical modulation techniques;
11. Control loops for synchronization of quantum-entangled sources.

Preferred Skills:

Ability to communicate effectively with other team members. Ability to design and program a Xilinx MicroBlaze embedded processor. Familiar with Xilinx Vivado and Vivado SDK. Experience with PCIe, CoaXpress, DVBS2 Error Correction, SC-PPM FEC, and PPM modulation and demodulation is also desired.

Education & Experience : Bachelor's and Master's degree with 8 years of relevant work experience.

Work Authorization : US Citizenship is required due to the nature of the work.
