ARQUIMEA , we are a technology company operating globally and providing innovate solutions and products in highly demanding sectors. Our areas of activity are Aerospace, Defense & Security, Big Science, Biotechnology and Fintech. We are looking for a Digital Signal Processing (DSP) Engineer with solid experience in the design, modelling and validation of signal-processing algorithms for Software Defined Radio (SDR) and real-time embedded systems. The initial focus of the position will be the development of modulation and demodulation algorithms for secure defense radio systems .

The role may also contribute to space communication payloads and other advanced signal-processing applications. Task to be performed

• 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.

, experience and candidate profile:

• University degree in Telecommunications Engineering, Electrical/Electronic Engineering, Physics, Mathematics or a related discipline.
• At least 5 years of professional experience in DSP algorithm development , preferably for SDR, telecommunications, space, aerospace, defense or another high-reliability sector.
• Strong foundation in digital signal processing and digital communications, supported by practical algorithm-development experience.
• Advanced proficiency in MATLAB and Simulink for modelling, simulation, analysis and verification of signal-processing systems.
• Proficiency in Python and C/C++ for modelling, test automation and reference implementations.
• Experience designing and developing SDR architectures and communication waveforms.
• Understanding of FPGA and SoC architectures and hardware/software partitioning for real-time signal processing.
• Proficient English, both written and spoken. Valuable
• Implementation of real-time DSP algorithms on FPGAs or SoCs.
• MIMO systems, digital beamforming or direction-of-arrival estimation.
• Defense communications or Electronic Warfare, including robust waveforms and interference or jamming mitigation.
• Satellite communication payloads and communication standards such as DVB-S2/S2X, CCSDS, 3GPP/LTE/5G or GNSS.
• Hands-on experience with RF laboratory instrumentation, such as signal generators, spectrum analyzers, vector signal analyzers and oscilloscopes.
