About us
VIAVI Engineers work with teammates to solve problems and build innovative software and hardware solutions that help our customers design, deploy and optimize all types of networks which enable their customers cell phone data and voice services for 5G, 4G and all types of wireless networks, enable cable systems and services, enable high speed data centers to operate, enable aircraft to fly safely, and enable your local government, police, fire departments, and military to operate radio communication.
In addition, VIAVI Engineers build modern software systems to ensure that all forms of information communication provide high level of service to customers.
What You'll Do
Modern C++ on Linux inside an SCA 4.1 core framework: waveform components and their ports, device abstractions, control and status APIs, and the network path that drives a T/Rx from a phone, tablet or PC — under real-time constraints, at high IQ rates.
Advanced VHDL on the digital chain: up- and down conversion, decimation and interpolation, FIR and CIC filtering, channelization, streaming interfaces, converter links, and full-bandwidth record and playback. You learn budget logic, DSP slices, bandwidth and latency.
The 1 MHz – 18 GHz path: LO and synthesizer planning, spurious and harmonic analysis, gain / noise figure / IP3 cascades, filtering and isolation, transmit linearity, receiver sensitivity and dynamic range, calibration, and the thermal realities of an all-weather ruggedized box.
IQ recording and playback, parametric signal synthesis, detection, classification and parameter estimation, wideband spectrum sensing. You prototype an algorithm, prove it against captured data, take it to fixed point, and hand it to the FPGA and software teams — closing the loop on the other three.
