You will collaborate across engineering disciplines to deliver manufacturable, maintainable, and reliable aircraft hardware.\nThe ideal candidate has demonstrated experience designing aircraft hardware and installation solutions and enjoys solving multidisciplinary integration challenges involving structures, avionics, propulsion, manufacturing, and production.\nWhat you'll do:\nIndependently design machined, fabricated, composite, and sheet metal components for aircraft applications.\nDevelop aircraft installation layouts that optimize packaging, accessibility, serviceability, manufacturability, and weight.\nDesign routing paths for EWIS, hydraulic, fuel, pneumatic, and ECS systems while coordinating interfaces with adjacent aircraft structures and subsystems.\nDevelop detailed engineering drawings, installation drawings, and assembly documentation in accordance with company drafting standards.\nMaintain CAD assemblies, product structures, BOMs, and engineering releases within PLM systems.\nApply GD&T and tolerance stack-up analyses to ensure manufacturable and interchangeable designs.\nSupport prototype aircraft builds, production integration, and manufacturing issue resolution.\nInvestigate installation and integration issues through structured root cause analysis and implement corrective actions.\nCollaborate with cross-functional teams to integrate avionics and other system components seamlessly within the aircraft\nPerform engineering calculations to support design decisions and evaluate structural adequacy.\nRequired qualifications:\nBachelor's or Master's degree in Mechanical Engineering or related discipline.\n3+ years of professional experience designing and integrating mechanical systems for aircraft, aerospace, defense, robotics, automotive, or other complex electromechanical products.\nDemonstrated experience designing machined, fabricated, composite, and sheet metal components from concept through production release.\nProficiency developing complex 3D CAD models, large assemblies, installation layouts, and detailed engineering drawings using NX, SolidWorks, CATIA, Creo, or equivalent CAD software.\nExperience managing engineering data, product structures, Bills of Material (BOMs), and drawing releases using PLM systems such as Teamcenter, Windchill, or 3DEXPERIENCE.\nWorking knowledge of aircraft installation practices, subsystem packaging, interface management, equipment mounting, and maintainability considerations.\nExperience developing installation layouts and routing solutions for EWIS, hydraulic, fuel, pneumatic, ECS, or similar mechanical systems.\nWorking knowledge of GD&T in accordance with ASME Y14.5 and experience performing tolerance stack-up analyses.\nExperience supporting prototype builds, manufacturing, aircraft assembly, installation, and production issue resolution.\nAbility to investigate integration issues, perform root cause analysis, and implement effective corrective actions.\nExperience collaborating with Manufacturing, Systems Engineering, Stress, Avionics, Supply Chain, Quality, and Test Engineering organizations throughout the product development lifecycle.\nStrong organizational, communication, and project management skills with the ability to manage multiple assignments simultaneously.\nAbility to obtain a S//SAR level security clearance desired.\nPreferred qualifications:\nExperience integrating aircraft subsystems on unmanned aircrafts, fixed wing, eVTOL, or other aerospace platforms.\nExperience leading mechanical work packages or owning subsystem-level hardware from concept through production.\nExperience performing structural hand calculations, free-body diagrams, load path evaluations, or preliminary stress analyses to support mechanical design decisions.\nExperience performing finite element analysis (FEA), including static, modal, vibration, fatigue, or thermal analyses.\nHands-on experience supporting build, production, testing, or hardware validation activities.\nFamiliarity with aircraft configuration management, engineering change processes, and formal product release workflows.\nExperience coordinating engineering activities with suppliers, manufacturing partners, or external engineering organizations.\nFamiliarity with FAA, DoD, MIL-STD, or commercial aerospace design standards.\nExperience mentoring interns or early-career engineers and reviewing engineering documentation for technical accuracy.","description_format":"text","description_chars":4624,"description_truncated":false,"requirements":{"experience_years_min":3,"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":["Military
