About the Job

Requirements

  • A Bachelor of Science, Master of Science, or PhD in Electrical Engineering, Applied Mathematics, Physics, or a related technical discipline is required.
  • Five to seven or more years of relevant work experience is required depending on degree: seven or more years with a BS or five or more years with an MS.
  • Experience in at least two areas such as RF/radar signal processing, optimization, waveform design, electronic warfare, machine learning, adaptive signal processing, AI/ML algorithm development, algorithm development, test and evaluation, model and simulation, systems engineering, test engineering, radar modeling, or RF systems prototyping.
  • Proficiency in one or more scientific or mathematical programming languages such as MATLAB, Python, or C/C++.
  • The ability to obtain a Top Secret security clearance is required; U.S. citizenship is required by the U.S. Government.
  • Strong mathematical, troubleshooting, written, and verbal communication skills are required.

Responsibilities

  • Design and apply signal-processing and machine-learning techniques to solve 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 capabilities to prototype systems.

Desired Qualifications

  • An active security clearance is preferred.
  • Experience with RF technologies in the defense sector, particularly sensing and electronic-warfare applications, including electronic attack, electronic protection, cognitive electronic warfare, and advanced electronic support-measures techniques and algorithms.
  • Experience with machine-learning tasks such as natural-language processing, image recognition, semantic segmentation, and reinforcement learning; approaches such as Bayesian, deep convolutional, and graph neural-network methods; and tools such as PyTorch, Ray, TensorFlow/Board, and MLflow.
  • Experience 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 that explain technical solutions at both high and deep levels.
