In this role, you will work across system architecture, performance analysis, modeling and simulation, supplier collaboration, and certification-ready design to deliver robust aerospace systems for a first-of-its-kind aircraft.\nThis is an opportunity for an experienced systems engineer who thrives in fast moving environments, enjoys solving complex multidisciplanary problems, and can independently drive technical work from concept through execution.\nResponsibilities:\nDevelop, validate, and maintain systems level models for environmental control and hydraulic power systems using Simulink, MATLAB, Python, among other tools.\nPerform analyses related to thermal management, airflow, pressure control, fluid dynamics, and system integration. \nSupport system architecture definition, requirements development, and verification planning. \nInterpret and apply FAA Part 25 regulations to ensure compliance throughout design and development. \nLead technical interactions with suppliers, including reviewing designs, managing deliverables, and ensuring alignment with program requirements. \nCollaborate with cross-functional engineering teams to support aircraft level integration and trade studies, including providing 3D layouts of equipment in CATIA.\nPrepare clear technical documentation, analysis reports, and presentations for internal and external stakeholders. \nRequirements\nRequired Qualifications\nBachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or a related field. \n8+ years of relevant experience in aircraft systems engineering, fluid systems, environmental control systems, hydraulics, thermal systems, or related aerospace systems. \nStrong experience with Simulink, MATLAB, and Python for modeling, simulation, and data analysis. \nSolid understanding of environmental control systems, hydraulic systems, or related aircraft subsystems. \nAbility to work independently, set priorities, and drive tasks to completion with minimal oversight. \nExcellent communication skills and a collaborative mindset. \nPreferred Qualifications\nFamiliarity with FAA Part 25 certification requirements and aircraft development processes. \nExperience managing suppliers or external partners, including technical reviews and schedule oversight. \nExperience supporting aircraft-level integration, system layouts, or equipment placement using CATIA or similar 3D design tools.","description_format":"text","description_chars":2654,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Professional
