Mechanical Design Engineer

Job description

AST SpaceMobile and our global partners are building the first and only space-based cellular broadband network to be accessible by standard smartphones. Called SpaceMobile, this ultra-powerful network is being designed to provide connectivity at 4G/5G speeds everywhere on the planet – on land, at sea and in flight. Position Overview We are seeking a Mechanical Design Engineer to support satellite mechanical subsystem and payload development programs. This role is responsible for structural architecture layout, primary and secondary structure design, analysis, assembly, and test support, including detailed design definition of parts and assemblies, management of mechanical interfaces between subsystems, and the analysis reports, interface control drawings, and manufacturing documentation that accompany them. The ideal candidate is innovative, hands-on, and thrives in fast-paced, cross-functional technical environments, capable of leading a small team while also executing assignments autonomously. Key Responsibilities: Perform mechanical design and computer-aided modeling of space hardware, including final detailed design definition of parts and assemblies and management of mechanical interfaces between subsystems. Conduct structural, mechanical system, and satellite payload equipment layout studies to determine optimal system architecture in terms of simplicity, performance, mass, and cost. Develop and maintain mechanical and structural design documentation at system and equipment level: mechanical analysis reports, interface control drawings, tooling and fixturing, and manufacturing documentation. Support creation of developmental and qualification test procedures (vibration, shock, TVAC, assembly). Prepare and present the information required to conduct thorough design and readiness reviews with management and peers. Coordinate with manufacturing and production to ensure successful transfer of information and that efficient processes are understood and documented. Evaluate and champion new technologies and methods. Qualifications Education: Bachelor's degree in mechanical engineering, aerospace engineering, or a related technical field; an advanced degree is preferred. Experience: A minimum of 12 years of hands-on experience in mechanical design, integration, and testing of spacecraft and spacecraft components. Preferred Qualifications: Strong technical skill in design of satellite assemblies for launch and on-orbit environments, as well as design for manufacturability. Experience using standard analytical tools and classical structural analysis methods to support sizing and trade studies. Knowledge of, or experience with, launch vehicle integration. Experience operating in a Windchill PLM environment. Advanced degree in mechanical or aerospace engineering. Soft Skills: Innovative and creative approach to problem solving, with a willingness to challenge the status quo. Demonstrated ability to work in a multidisciplinary team with other engineers. Ability to lead a small team while also carrying assignments autonomously. Flexibility and adaptability in a fast-paced, dynamic environment. Excellent English written and verbal communication skills. Technology Stack: CAD: Siemens NX preferred; CATIA, SolidWorks, or CREO also considered. PLM / product data management: Windchill. Standard analytical tools and classical structural analysis methods for sizing and trade studies. Physical Requirements Ability to work in a standard office environment and use a computer for extended periods. Willingness to travel 25%–50% of the time. This job description may not be inclusive to the duties and responsibilities listed. Additional tasks may be assigned to the employee from time to time or the scope of the job may change as needed by business demands .
