Specialist, Mechanical Engineer - Dynamics Analyst (Space Optical Systems)

About the role

L3Harris is seeking a highly skilled Dynamics Analyst to perform design, analysis, modeling, and testing of high-performance controls for electro-mechanical and optical-mechanical systems with a focus on Attitude Control Systems, Controls, LOS/Jitter, and/or dynamic testing.

Responsibilities

• Control Theory: Applying classical and modern control theory concepts such as stability, feedback control, and robustness. Utilizing analysis tools like Bode, Nyquist, Nichols, pole-zero plots, root-locus, and frequency-response analysis.
• Control Systems: Conducting analysis, synthesis, development, and implementation of feedback control systems. This includes developing models as state-variable equations, transfer functions, and/or block diagrams to determine dynamic systems characteristics, and analyzing both time and frequency responses.
• Structural Dynamics and Vibration Analysis: Performing structural dynamics and vibration analysis, including random vibration and acoustic analysis, design, measurement, and computation of multi-degree-of-freedom systems.
• Computational Methods: Employing finite-element-based computational methods, dynamic testing methods, and modal analysis (both analytical and experimental).
• Optical Performance Analysis: Evaluating system-level optical performance related to pointing, smear, and jitter.
• Digital Signal Processing: Applying fundamental concepts and techniques of digital signal processing theory and its applications, including discrete-time signals, systems, and modern digital processing algorithms for both time-domain and frequency-domain methods.
