Senior Signal Processing & Modem Development Engineer

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
