• Design, analyze, and optimize single-loop and multi-loop PID control systems.
• Perform modeling and simulation of actuator systems for aerospace and related applications.
• Validate simulation models against test data and resolve performance discrepancies.
• Develop actuator performance requirements and technical specifications.
• Conduct trade studies to evaluate new actuator system architectures and technologies.
• Support anomaly investigations and root-cause analysis activities.
• Review and analyze actuator system test results and recommend corrective actions.
• Collaborate with systems, mechanical, and electrical engineering teams.
• Perform kinematic analysis and mathematical modeling of 3-bar and 4-bar mechanisms.
• Generate technical reports, analyses, and engineering documentation.
• Support modification and enhancement of existing actuator designs and models.

Must-Have Qualifications

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Controls Engineering, or a related discipline.
• 2+ years (Level 3) or 4+ years (Level 4) of direct actuator modeling experience.
• Experience developing actuator performance requirements and specifications.
• Expertise in electro-mechanical actuation systems.
• Expertise in electro-hydraulic actuation systems.
• Strong experience with MATLAB and Simulink.
