Senior Signal Processing & Modem Development Engineer - Hertfordshire.

£ Competitive Salary and Benefits.


Seeking a senior engineer to take ownership of our modem specifications and modelling as part of a development team. This could be an opportunity for someone with solid experience and a passion for digital signal processing to take technical ownership of an exciting area of technology within the company.


Key Objectives

  • Specification, modelling and simulation of RF modems.
  • Participate in development and maintenance/ enhancement of software defined radio products.
  • Definition of air-interfaces including ability to customise existing and standard air interfaces.
  • Thereby to support development, integration and validation of FPGA SoC solutions for use in satellite communications applications including terminals and test tools.


Responsibilities

  • Work with system requirements to identify and define appropriate air-interfaces.
  • Design RF modems using existing processing blocks and specification of new blocks.
  • Use modelling and simulation tools to define, test and refine specifications.
  • Produce or validate bit-correct simulations for the modems.
  • Support or carry out modem development in VHDL or software; troubleshoot development issues.
  • Work as part of a small focussed team to deliver full stack solutions.


Skills/Experience Required
Mandatory:

  • Detailed familiarity with radio communication air interface specifications; thorough understanding of digital modulation techniques; understanding of access technologies including CDMA, TDMA etc.
  • Specification of RF modems.
  • Modelling and simulation of digital signal processing systems in general and RF modems in particular.
  • Development of modems in software defined radio (SDR) solutions, either in software or using hardware description languages (HDL).
  • Use of tools to perform simulation-based validation of algorithm design e.g. through HDL-based test benches, MALAB/ Simulink, Octave.


Preferable:

  • Definition and maintenance of link budgets.
  • System design and development of FPGA System on a Chip (SoC) architecture definition and partitioning, algorithm implementation, HW/SW interfaces.
  • Track-record in delivery of integrated SoC solutions for digital signal processing
  • Software development.
  • Xilinx Design Tools (ISE/EDK/SDK, Vivado), C/C++, Windows and Linux environments.
  • Xilinx background, Zynq SoC (e.g ZC702)
  • Analogue Devices, e.g. AD-FMComms2 hosting AD9361
  • Programming of DSPs in relation to modems


Personal Profile:

  • Professional engineering approach
  • Proven ability to work within tight timescale and budgetary constraints
  • Proven ability to produce clear, concise and unambiguous documentation confirming to applicable technical and quality standards
  • Proven ability to work as an integral part of a highly-focused team
  • Proven ability to take full responsibility for the delivery of critical system components
  • Proven ability to develop innovative and efficient solutions to defined problems
  • Proven ability to produce and present clear, concise and unambiguous presentations to customers and other clients
  • Good communication skills
