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 The Launch Operations Mechanical Engineer plays a critical role in the final, high-stakes phase of mission success.

This position is responsible for overseeing mechanical processes and equipment at the launch base, ensuring all systems adhere to rigorous aerospace standards. You will bridge the gap between design and flight, managing the physical build, qualification, and configuration of the satellite while supporting the design of the essential Mechanical Ground Support Equipment (MGSE) required for site operations.

Key Responsibilities

: Lead mechanical integration efforts at the launch site, ensuring the satellite is flight-ready and configured according to mission specifications. Design and implement Mechanical Ground Support Equipment (MGSE) tailored for launch site operations, including handling fixtures, transport containers, and integration stands. Oversee the mechanical assembly and qualification testing of satellite hardware, ensuring every component meets safety and performance standards prior to liftoff.

Enforce strict aerospace industry standards across all mechanical operations to mitigate risk and ensure mission reliability. Work closely with integration, systems, and launch vehicle teams to synchronize mechanical activities with the overall launch schedule.

Qualifications

Strong background in mechanical engineering with a focus on aerospace hardware integration and MGSE design. Experience working in high-pressure launch base or cleanroom environments where precision is paramount. , CREO, SolidWorks, or Catia) for developing ground support hardware.

Deep understanding of aerospace mechanical standards and safety protocols. Ability to troubleshoot complex mechanical issues on the fly during critical integration windows. Education: Bachelor's degree in mechanical engineering or aerospace engineering.

Experience: A minimum of 5 years of direct experience in the aerospace industry or a high-flow manufacturing environment. Experience navigating the lifecycle of a product from design/build through to final qualification and deployment.

Preferred Qualifications

: Experience with automated integration systems used in large-scale aerospace assembly. Advanced proficiency in Geometric Dimensioning and Tolerancing (GD&T) to ensure high-precision interfaces between the satellite and MGSE. Previous experience leading small teams or managing specific hardware subsystems through a full launch campaign.

Soft Skills: Strong interpersonal skills. Proven ability to collaborate effectively within cross-functional teams. Excellent written and verbal communication skills are essential.

Meticulous attention to detail to ensure the accuracy of all documentation and project deliverables.

Requirements

Capable of working hands-on with flight hardware, test setups, and precision instruments. Ability to lift and move up to 25 lbs. Availability for occasional extended shifts.
