Communication Systems / DSP Engineer | Next-Gen Wireless Comms | Start up | Oxford / Hybrid | £70,000pa - £80,000pa:
 
A once in a lifetime opportunity has arisen for a Communication Systems / DSP Engineer to have a majority impact in the development of next generation wireless communications. Our client is an early stage, fast paced, independently funded start up, with strong links to the University of Oxford. Led by a talented team with considerable sector experience and specialist subject knowledge, their mission is to enable safe and efficient communication systems which will ultimately protect our way of life. By joining them, the Communication Systems / DSP Engineer will be seriously contributing to critical technology that will save lives and ensure our society remains safe in an ever-changing world.
 
This Communication Systems / DSP Engineer role will focus on the design, implementation, optimisation, and validation of advanced wireless communication algorithms for next-generation software-defined radio systems.  Key responsibilities will include:

• developing and evaluating PHY and data-link layer algorithms for wireless communication systems;
• conducting system-level modelling and simulation in MATLAB/Python for algorithm development and performance analysis;
• implementing floating-point and fixed-point DSP algorithms in C/C++ for real-time embedded and SDR-based systems;
• designing, analysing, and optimising signal processing functions including modulation/demodulation, synchronisation, channel estimation, equalisation, beamforming, and error-correction coding;
• integrating, profiling, and optimising algorithms for real-time execution on embedded compute platforms;
• prototyping and validating communication systems using SDR hardware in laboratory and over-the-air environments;
• troubleshooting and resolving real-world PHY/DSP issues including RF impairments, timing/frequency synchronisation problems, numerical precision effects, and performance bottlenecks;
• working closely with systems, FPGA, RF, and software engineers to integrate and validate end-to-end wireless solutions;
• contributing to test planning, experimental evaluation, technical documentation, and design reviews.

Essential Experience & skills:

• Master's degree, PhD, or equivalent industry experience in Electrical Engineering, Communications, Signal Processing, Applied Mathematics, or a related discipline;
• strong practical experience developing and debugging DSP and wireless communication algorithms in real systems;
• strong proficiency in MATLAB, C/C++, and Python for simulation, implementation, and analysis;
• strong understanding of digital communication and PHY-layer techniques, including OFDM, MIMO, synchronisation, channel estimation, equalisation, and forward error correction;
• experience implementing and optimising DSP algorithms for real-time or embedded environments;
• hands-on experience with SDR platforms and laboratory-based system bring-up, integration, and debugging;
• strong analytical and problem-solving skills, including the ability to diagnose system-level and implementation-level issues;
• ability to work effectively across algorithm, software, FPGA, and RF domains;
• eligibility to work on projects related to the UK Defence and Security sector.

Desirable

• 5+ years of industry experience in wireless communications, SDR, or embedded DSP systems;
• experience with commercial or research wireless standards (e.g. LTE, 5G NR, Wi-Fi, tactical communications, satellite communications);
• experience with fixed-point optimisation, SIMD/vectorisation, and performance tuning on embedded processors;
• experience with FPGA-based signal processing workflows and hardware/software co-design;
• expertise in one or more of:
  • digital signal processing;
  • wireless PHY design;
  • error-correcting codes;
  • adaptive signal processing;
  • machine learning applied to communications systems;
• experience conducting RF or over-the-air testing in laboratory environments;
• familiarity with Linux-based embedded development environments and real-time systems.
