AST SpaceMobile • Midland, TX

17d

About The Position

AST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today’s five billion mobile subscribers and finally bring broadband to the billions who remain unconnected. Position Overview We are seeking a Senior Mechanical Engineer to support satellite mechanical systems and payload development across systems engineering, mechanical design, structural analysis, assembly, integration, and test activities. This role requires strong technical expertise, creativity, and the ability to challenge traditional approaches. The engineer will collaborate across multidisciplinary teams, lead small groups when needed, and manage assignments with a high degree of autonomy to advance spacecraft mechanical architecture, performance, and manufacturability.

Requirements

• Master’s degree in mechanical engineering or a related technical discipline.
• A minimum of 10 years of hands-on experience in mechanical design, integration, and testing of spacecraft and spacecraft components.
• Strong interpersonal skills with the ability to collaborate effectively within cross-functional teams.
• Excellent written and verbal communication skills.
• High attention to detail to ensure accuracy in technical documentation and engineering deliverables.
• Adaptability and comfort working in a fast-paced, dynamic environment.
• CAD tools: Autodesk Inventor (preferred), CATIA, SolidWorks, CREO.
• Standard engineering analysis and documentation tools.
• Ability to work in a standard office environment and operate a computer for extended periods.
• Occasional hands-on work in assembly, integration, and testing environments.

Nice To Haves

• Experience with launch vehicle integration.
• Familiarity with Autodesk Inventor (preferred), CATIA, SolidWorks, or CREO.
• Demonstrated ability to design spacecraft assemblies for launch and on-orbit environments, including design for manufacturability.

Responsibilities

• Perform spacecraft mechanical system and payload layout studies to optimize architecture for simplicity, performance, mass, and cost.
• Develop and maintain mechanical and structural design documentation at the system and equipment level, including manufacturing drawings, interface control drawings (ICDs), assembly/process documentation, and test plans.
• Prepare and present technical content for design reviews, readiness reviews, and engineering checkpoints.
• Troubleshoot mechanical anomalies and failures; conduct root-cause analyses and implement corrective actions.
• Collaborate closely with manufacturing and production teams to ensure effective transfer of designs, processes, and technical information.
• Evaluate, promote, and integrate new technologies, methods, and processes to improve mechanical design and production efficiency.
• Track drawing release progress to meet program schedules and business objectives.
