Senior DSP Engineer: SDR for Space & Defense RF

Arquimea; Torrejón de Ardoz; On-site; EUR 70,000 - 115,000; Full time

Job summary

ARQUIMEA is seeking a Digital Signal Processing (DSP) Engineer to design, model and validate signal-processing algorithms for SDR and real-time embedded systems, with initial focus on secure defense radio systems.

You will develop modulation/demodulation chains, digital filters and RF processing, model with MATLAB/Simulink, Python and C/C++, and work with FPGA/SoC teams to deploy on real-time platforms.

Qualifications

• University degree in Telecommunications Engineering, Electrical/Electronic Engineering, Physics, Mathematics or related.
• At least 5 years of professional experience in DSP algorithm development, preferably SDR/space/defense.
• Strong foundation in digital signal processing and communications, with practical development experience.
• Advanced proficiency in MATLAB and Simulink for modelling, simulation and verification.
• Proficiency in Python and C/C++ for modelling and reference implementations.
• Experience with SDR architectures and real-time signal processing on FPGA/SoC.
• Proficient English, both written and spoken.

Responsibilities

• Define, develop and validate DSP algorithms for space and defense communication systems.
• Design modulation and demodulation chains, digital filters, sample-rate conversion, channelization and spectral-processing functions.
• Develop algorithms for synchronization, channel estimation, equalization, error correction, interference mitigation, noise reduction and non-linearity correction.
• Create and validate signal-processing models using MATLAB/Simulink, Python and C/C++, evaluating solutions through quantitative performance metrics.
• Collaborate with FPGA/digital hardware and embedded software teams to integrate algorithms into real-time FPGA, SoC and processor-based platforms.
• Deploy prototypes and characterize end-to-end performance under representative conditions using RF and electronic laboratory equipment.
• Work within multidisciplinary engineering teams and contribute to technical reviews, validation activities and project planning.
