In this role, you will provide hands-on mechanical expertise for the integration of ruggedized electronics and mission-critical hardware into ground- and sea-mobile platforms. You will support the design and mechanical integration of military electronics and effector systems, develop and maintain 3D CAD models, perform structural and thermal analyses, and assist with system-level integration and qualification activities. The ideal candidate has a strong foundation in mechanical CAD and design principles, hands-on prototyping experience, and a bachelor's degree in Mechanical Engineering or a related discipline.\nMissions\nSupport the design and mechanical integration of military electronics and effector systems with critical platform structures and mechanisms.\nDevelop and maintain 3D CAD models, assemblies, and interface control documentation (ICDs) to support multi-disciplinary system integration.\nAssist in the design of mechanical structures, frames, mounts, enclosures, and mechanisms subject to shock, vibration, thermal, and environmental constraints.\nProfil recherché\n - The ideal candidate has a strong foundation in mechanical CAD and design principles, hands-on prototyping experience (from coursework, internships, or personal projects), an interest in ruggedized hardware design, and the drive to learn quickly in a fast-paced, cross-disciplinary engineering environment- Exposure to structural analysis methods (hand calculations, FEA) through coursework or projects\n- Coursework, internship, co-op, or project experience in mechanical design, structures, or system integration (aerospace/defense exposure a plus but not required)\n- Bachelor's degree in Mechanical Engineering or a related discipline (completed or expected within the next few months)\n- Foundational understanding of mechanical interfaces, tolerancing, alignment, and installation practices\n- Proficiency with CAD tools (e.g., SolidWorks or equivalent) for assemblies and top-down design\n- Strong communication skills and eagerness to learn from senior engineers in a multi-project environment\n- Ability to obtain and maintain a U.S. security clearance\n- Coursework or project experience related to ruggedized hardware, military standards (e.g., MIL-STD-810), or environmental qualification\n- Experience with mechanisms and actuation systems, including linkages, bearings, motors, hydraulics, pneumatics, gimbals, or rotary joints (e.g., from capstone projects, clubs, or competitions)\n- Familiarity with military-style connectors (e.g., mil-circular 38999, ARINC, micro-D)\n- Familiarity with at least one commercial FEA or multiphysics simulation package (NASTRAN, ABAQUS, ANSYS, CFD codes, COMSOL, etc.)\n- Hands-on prototyping experience, including additive manufacturing, CNC machining, or other fabrication techniques (e.g., through robotics teams, maker clubs, or personal projects)\n- Involvement in relevant engineering clubs, competitions (e.g., SAE, Formula SAE, robotics teams), or research projects","description_format":"text","description_chars":3077,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["C4ISR","Defense
