About the Role

The Processing, Guidance and Controls (PG&C) Center within the Systems Engineering and Test Capabilities Discipline is seeking a Sr. Systems Engineer specializing in EO/IR or RF Signal Processing to join our team in Tucson, AZ. You will collaborate in the design, development, prototyping, integration, testing, and performance assessment of radio frequency (RF) or electro-optical/infrared (EO/IR) algorithms and models. These algorithms are used across products and new business initiatives to extract and exploit sensor signals for calibrating and denoising raw sensor data, detecting, acquiring, tracking, and classifying objects of interest, and sensor fusion.

Responsibilities

• Act as a seasoned professional with advanced knowledge of signal processing to support development, execution, and completion of complex missile systems program objectives.
• Use and modify simulations for the design, development, prototyping, integration, testing, and performance assessment of signal processing algorithms and models.
• Participate in engineering lab environments to test, verify, and validate sensor models and signal processing algorithm performance in accordance with requirements.
• Focus on integration of algorithms into hardware and collaborate in all development phases from program start-up to live-fire testing.
• Support design reviews, peer reviews, and technical briefings to parties within and outside your discipline.
• Share knowledge and mentor others.

Requirements

• Bachelor’s Degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 5 years of relevant prior experience.
• Signal processing experience in the EO/IR, RF, Sonar, or Acoustic domains.
• Experience with the C programming language, or Object-Oriented Programming experience with C++, C#, or Java.
• Experience with algorithm design, implementation, analysis, testing, and optimization.
• Ability to obtain and maintain an Interim Secret U.S. government-issued Security Clearance prior to start date, with the ability to obtain special program access after start.
• Active and transferable U.S. government-issued security clearance is required prior to start date.

Preferred Qualifications

• Advanced Degree in Electrical Engineering, Computer Engineering, Physics, or Applied Math.
• Experience with missile systems applications supporting customer programs.
• Experience with version control tools such as Azure DevOps and Git.
• Practical experience in multiple EO/IR, RF, sonar, or acoustic algorithms such as edge detection, segmentation, image restoration, adaptive processing, beamforming, angle estimation, synthetic aperture processing, waveform design, tracking, feature extraction, or classification/recognition.
• Proficiency in using MATLAB or Python for analysis of data sets.
• Strong communication skills, capable of presenting analysis to technical and non-technical audiences.
• Experience with hardware/software integration.
• Ability to interface with adjacent engineering disciplines such as Guidance, Navigation, and Control; Software Engineering; Systems Engineering; or Hardware Engineering.

Benefits

• Medical, dental, and vision insurance.
• Life insurance, short-term disability, and long-term disability.
• 401(k) match.
• Flexible spending accounts.
• Flexible work schedules.
• Employee assistance program.
• Employee Scholar Program.
