The Role:
As a Sr. Digital RF Engineer, you will engage with an experienced cross-disciplinary staff to conceive and design innovative product solutions. You will work closely with an internal inter-disciplinary team, and outside partners to drive key aspects of product definition, execution and optimization. You must be responsive, flexible and able to succeed within an open collaborative peer environment.
As a senior member of the Digital RF Systems team, you will be responsible for architecture, simulation, and End to End model implementation (Matlab/C/C++/System C/HDL) of hybrid and digital phased arrays beam forming systems. Based on system level constraints, you will develop a solution supporting high throughput / availability, low power, flexibility in capacity, and optimized for RF system constraints. Members of this team will focus on the signal chain from modem interface to RF front-end module.

You also will be providing reference models for the IC (Integrated Circuit) design team, be involved in the verification and validation of the algorithms and the Phased arrays systems from concept to space ready hardware and software.
In this role you will:
· Innovate for lowest power consumption and highest reliability
· Develop and model Digital Signal Processing algorithms for FPGA and ASIC implementation,
· Develop and model multi-beam beamforming systems
· Develop and model RF transceivers behavioral models
· Develop and model impairments compensation and system calibration methods for the phased array system
. Innovate to enhance in spectral efficiency and address RF impairments
· Work collaboratively with network and communications systems as well as chip and Firmware implementation teams
· Simulate / trade-off analysis / validate digital beam forming implementations and architectures
· Bring up prototype and production systems in conjunction with implementation teams
· Meet with vendors and technology suppliers to select technologies
