Description: The Performance‑Analysis Engineer will own and lead performance‑modeling work‑packages for advanced aerospace and defense systems. The role focuses on developing high‑fidelity analytical and simulation models that predict mechanical‑system performance (e.g., propulsion, launch vehicle dynamics, thermal‑mechanical interaction) throughout the product lifecycle. The engineer will provide technical guidance to junior analysts, interface with multidisciplinary teams, and ensure that performance predictions meet program requirements and schedule milestones. In this role your responsibilities will include: Performance Modeling & Simulation • Build and validate physics‑based performance models using tools such as MATLAB/Simulink. • Conduct steady‑state and transient performance analyses (thrust, torque, power, efficiency, burn‑rate, trajectory, vibration) for propulsion, actuation, and structural subsystems. • Integrate multi‑physics effects (thermal‑mechanical,...

Description: The Senior Thermal Engineer will execute thermal‑analysis activities for aerospace and defense systems under the guidance of senior thermal leads. This role focuses on developing thermal models, performing steady‑state and transient heat‑transfer analyses, supporting design decisions for propulsion subsystem, and cooling solutions. In this role your responsibilities will include: Thermal Modeling & Analysis • Build and validate 2‑D/3‑D thermal FEM models using ANSYS Thermal Desktop • Conduct steady‑state, transient, conductive, convective, and radiative heat‑transfer studies. • Generate temperature, heat‑flux, and thermal‑gradient plots; calculate margins of safety. Design Integration • Work with system and subsystem engineers to incorporate thermal constraints early in the design cycle. • Provide thermal sizing recommendations for subsystem. Verification and Validation • Assist in defining test‑article requirements, instrumentation layout, and...

Description: The Stress Analysis Engineer will own moderate‑to‑complex structural‑analysis work‑packages, mentor junior analysts, and provide technical leadership for propulsion subsystem stress analyses. The role bridges detailed finite‑element modeling with design‑review participation, ensuring that stress analysis meets program performance, reliability, and safety requirements. Advanced Stress Analysis • Lead static, dynamic, and fatigue analyses using linear and non linear solutions in Siemens NX. • Develop and validate high‑fidelity FEM models (meshing strategy, material definition, boundary conditions). • Perform load‑case generation and factor‑of‑safety assessment for critical structures Design Integration & Trade Studies • Translate system‑level requirements into detailed stress‑analysis specifications. • Provide design‑size recommendations, reinforcement concepts, and material substitutions to meet weight‑strength targets. • Participate in multidisciplinary trade...
