Modelling Simulation Jobs in Arlington, VA (NOW HIRING)

The Electronic Warfare and Novel Capabilities Group (EWNC) develops and delivers advanced signal processing algorithms and prototype systems for next-generation radar and electronic warfare technologies.

EWNC fosters a culture of innovation and collaboration. We investigate cutting edge technologies and interface with engineers across sectors and divisions at STR and researchers at academic institutions and industry partners to develop practical and effective solutions to RF sensing and counter-sensing challenges. If you're seeking an opportunity to apply your deep technical knowledge and creativity to make a lasting impact, we invite you to join us.

As a Lead Algorithm & Signal Processing Researcher, you’ll have the opportunity to develop state-of-the‑art algorithms and techniques for sense making and sensor decision making, from signal detection and classification, to electronic support measures, attack, and protection, to cognitive EW and more.

• Design and apply cutting‑edge signal processing and machine learning techniques to solve complex radar and RF sensing and counter‑sensing challenges
• Design and implement models and simulations for advanced RF systems
• Lead small teams and projects
• Support business development and proposal writing efforts
• Collaborate with diverse teams to deploy cutting‑edge capabilities to prototype systems

• This position requires the ability to obtain a Top Secret security clearance, for which U.S. citizenship is needed by U.S. Government
• BS, MS, or PhD in Electrical Engineering, Applied Mathematics, Physics, or related technical discipline
• 5-7+ years of relevant work experience depending on degree (BS +7 years or MS +5 years)
• Experience in two or more of the following areas:
• RF/radar signal processing, optimization, waveform design, electronic warfare, machine learning, adaptive signal processing, AI/ML algorithm development, algorithm development, test & evaluation, model & simulation, or systems engineering, test engineering, radar modelling, or RF systems prototyping
• Proficiency in one or more scientific or mathematical programming languages, such as MATLAB, Python, and C/C++
• Strong mathematical, troubleshooting, written, and verbal communication skills

• Active Security Clearance
• Experience with:
• RF technologies in the defense sector, particularly for sensing and electronic warfare applications including electronic attack, electronic protection, cognitive EW, and advanced electronic support measures techniques and algorithms
• Machine learning tasks such as natural language processing, image recognition, semantic segmentation, reinforcement learning, approaches such as Bayesian, deep convolutional and graph neural network methods, and tools such as PyTorch, Ray, TensorFlow/board, and MLflow
• Interacting with decision‑makers and customers to translate mission needs into an end‑to‑end analytical solution
• Ability to apply novel, innovative and interdisciplinary approaches to challenging engineering problems
• Ability to create and present briefings to customers and senior management to provide both high‑level and deep technical solution explanations

Join EWNC and help shape the future of RF sensing and electronic warfare by developing innovative technologies that transition from advanced research into operational prototype systems. While this position is ideally suited for a Lead Engineer, applicants whose qualifications closely align with the requirements are encouraged to apply. We have opportunities for talented engineers at multiple experience levels in our MA, VA, and OH office.
