Mechanical Engineer II

Job Type Full-time Description Description TRI Austin seeks a hands-on Mid-Level Mechanical Engineer to join our multidisciplinary R&D team. This role combines mechanical design and analysis, prototype fabrication and testing, and contributions to technical capture activities, including customer discovery, solution development, and proposal writing. The position is tailored for engineers who have worked on DoD or military programs, have practical materials experience, and are eager to contribute to winning and executing government research projects. Key Responsibilities Contribute to all phases of mechanical design from concept to prototype, including 3D CAD, detailed drawings, BOMs, and manufacturability reviews. Rapidly iterate designs to support fabrication and field testing. Fabricate, assemble, and test prototypes in the lab and at field sites; write and execute test procedures, analyze test data, and document results in technical reports and presentations. Perform engineering analyses using FEA or other tools to support design decisions and risk reduction. Engage in hands-on composite work: fabricate, repair, and test fiber-reinforced systems (layups, curing, NDE, thermomechanical testing) and translate materials behavior into robust designs. Support proposal and capture efforts by developing technical approaches, preparing scopes of work, writing technical sections, and providing inputs for cost and schedule estimates. Integrate mechanical, electrical, and software subsystems where applicable; coordinate with vendors, subcontractors, test resources, and external collaborators under the guidance of senior staff. Assist in mentoring junior engineers/technicians and maintain rigorous engineering documentation (lab notebooks, drawings, test logs). Requirements Required Qualifications B.S. or M.S. in Mechanical Engineering, Aerospace Engineering, or a closely related field. Demonstrated hands-on experience (typically 3-7 years) developing and testing mechanical hardware for defense, aerospace, maritime, or other demanding applications. Experience with composite structures or other advanced materials is strongly preferred. Experience contributing to technical proposals, white papers, statements of work, or research plans for customer-funded technical approaches. Experience contributing to SBIR/STTR, BAA, IRAD or other DoD capture efforts is a plus. Experience supporting DoD, US Navy, or other military programs (program execution or customer interactions). Proficiency in a 3D CAD system and common engineering analysis and simulation tools (FEA, CFD, etc.). Strong technical writing and verbal communication skills; ability to present technical information clearly to stakeholders. Ability to obtain and maintain a U.S. Government security clearance. Preferred Qualifications Direct experience with defense platform or mission areas, such as weapon and launcher systems, missiles or rocket motors, naval shipboard equipment, unmanned maritime systems, aircraft hardware, or platform sustainment. Familiarity with relevant manufacturing methods such as machining, welding, composite processing, additive manufacturing, sheet-metal fabrication, castings, and coatings. Experience taking hardware through requirements development, design reviews, environmental qualification, integration, and field demonstration. Experience designing, fabricating, testing, or repairing fiber-reinforced composite structures. Experience contributing to project planning, including tracking tasks against budgets and schedules. What We Offer Mission-driven R&D supporting the Warfighter and government customers in a collaborative small-business environment. Opportunity to work across a broad portfolio (materials, ocean/vehicle systems, instruments, and advanced components) and to grow your skills in both technical execution and business development. Competitive salary (DOE) and benefits, with hands-on R&D work in Austin, TX. The ability to obtain a US DoD security clearance is mandatory.
