This Adaptive Optics Control Modeling, Simulation, and Analysis Engineer, Steward Observatory position is with University of Arizona in Tucson, AZ.
Advanced Dynamics Modeling and Simulation Development: Using advanced engineering principles and extensive knowledge of system dynamics, independently develop and execute high-fidelity modeling and simulation frameworks for flexible-body space instrumentation and adaptive optics systems. Work is performed with considerable latitude in determining objectives and approaches, and includes deriving transfer functions, state-space, and discrete-time models from first principles, conducting kinematic transform derivations and coordinate system analyses, and implementing simulation environments in MATLAB and Simulink. Problems frequently require the development of novel analytical methods with a high degree of innovation and creativity; the candidate must be able to evaluate multiple approaches and exercise expert judgment in selecting the most appropriate methodology. May provide technical guidance and share simulation best practices with graduate students and junior engineers supporting the project. Complex Analysis and Performance Trades: Applying extensive knowledge of control theory and frequency-domain methods, independently perform time- and frequency-domain analyses to evaluate, predict, and optimize system performance for space-based instruments under development. This includes conducting performance studies examining line-of-sight error budgets as a function of reaction wheel speed combinations, Fine Steering Mirror (FSM) controller analyses and loop closure timing studies, and hardware performance trade studies (e.g., isolator frequency impact, actuator performance, and quantization effects on motion profiles and precision). The candidate will determine the scope and methodology of analyses without appreciable direction and will communicate findings and their design implications to team members, key stakeholders across engineering disciplines, and project sponsors in formal reviews. Assembly, Integration, and Test (AI T) Support: Using thorough knowledge of verification and validation methods, independently provide simulation and analysis support for Assembly, Integration, and Test (AI T) activities at both component and system levels. This includes generating test plans for characterization and verification, working with team members to execute these plans, and correlating test data with analytical models. The candidate will exercise expert judgment in identifying discrepancies between predicted and measured performance and in determining appropriate corrective actions, including cases that require the development of new approaches. Communicate AI T findings and their system-level implications to engineering team members and stakeholders. Knowledge, Skills, and Abilities (KSAs): Extensive knowledge of system dynamics for flexible-body motion applications, including transfer functions, state-space, and discrete-time system modeling. Advanced skill and demonstrated expertise in kinematic transforms, coordinate system analysis, and rigid- and flexible-body mechanics. Thorough knowledge of control theory, including loop closure, stability analysis, and frequency-domain methods. Advanced proficiency with MATLAB and Simulink simulation environments. Ability to apply engineering principles independently to develop novel analytical approaches for complex problems without clear precedents. Ability to exercise expert judgment in selecting and adapting methodologies to meet project needs. Ability to provide technical guidance to graduate students and junior engineers. Ability to communicate complex technical findings clearly to engineering team members and cross-functional stakeholders. Strong analytical and problem-solving skills with a high degree of innovation and creativity. Physical Requirements and Environmental Demands: Lift and transport equipment, tools, and materials (up to 30-50 lbs.) as required. Tolerate exposure to extreme heat, extreme cold, and varying weather conditions. May be required to work in proximity to mechanical and electrical equipment during instrument assembly, integration, testing, and verification activities. May occasionally work at elevated heights, on ladders or platforms, and near moving mechanical systems while supporting telescope and instrumentation operations. May be exposed to chemicals, compressed gases, and other materials commonly found in engineering and research laboratory settings. Follow established safety protocols and personal protective equipment (PPE) requirements.
