Digital Signal Processing Algorithm Development Specialist

At Indra Group, we protect what matters most.

From our Defense unit, we develop advanced technological solutions that reinforce national and international security.

💻 Join our European projects team!

We want to hire an Algorithm Development Specialist (Artificial Intelligence) with experience in the design and development of advanced algorithms for electromagnetic spectrum analysis and intelligent RF signal processing to join projects involving analysis, detection, classification, and identification of emitters in complex and contested environments.

💡 What will you do?

• Design and development of advanced algorithms for electromagnetic spectrum analysis in complex and contested environments.
• Development of deinterleaving and blind source separation techniques.
• Implementation of robust RF signal detection and classification algorithms in low SNR and high spectral congestion conditions.
• Identification and tracking of non-cooperative emitters.
• Development of solutions based on digital signal processing (DSP), time-frequency analysis, and statistical and probabilistic modeling.
• Robust feature extraction from complex signals.
• Design of hybrid architectures that combine physical fundamentals with advanced deep learning techniques applied to spectrograms, temporal sequences, and complex signal representations.
• Design, fine-tuning, and optimization of low-level deep learning models.
• Analysis of model stability, generalization, and reproducibility.
• Efficient implementation and deployment of algorithms in HPC and GPU environments, optimizing latency and throughput.
• Application of best practices in experimentation, rigorous validation, bias control, and definition of operational metrics.
