AST SpaceMobile • Titusville, FL

6d • Remote

About The Position

AST SpaceMobile is building a global cellular broadband network in space that will connect directly with standard, unmodified mobile devices for commercial and government applications. The company’s mission is to address connectivity gaps for mobile subscribers and people who remain unconnected.

The posting describes a Lead Launch Vehicle Systems Engineer who serves as AST’s primary technical interface to launch vehicle providers. Based remotely near Cape Canaveral, Florida, the role owns launch vehicle interface definition and Interface Control Documents (ICDs), integrates spacecraft with multiple launch vehicles, and acts as AST’s technical authority at the launch site through campaign execution and launch. The role requires hands-on spacecraft-launch-vehicle integration experience from interface definition through launch-site operations, and the ability to make real-time technical decisions in the field while coordinating with providers, ranges, and internal teams across multiple sites.

Requirements

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Systems Engineering, or a related technical field.
• At least 8 years of aerospace systems engineering experience.
• At least 3 years in launch vehicle integration, launch vehicle interface management, or launch site operations on at least one spacecraft or payload that has flown.
• Strong interpersonal skills and demonstrated ability to lead and influence launch providers, range and facility personnel, and internal teams without direct authority.
• Excellent written and verbal communication skills, including briefing technical and executive audiences and negotiating technical positions with external partners.
• Sound judgment and composure when making technical decisions under schedule pressure and during launch campaigns.
• Ability to operate in ambiguity and define a path forward when requirements are incomplete or interfaces are still maturing.
• Meticulous attention to detail in ICDs, verification records, and launch documentation.
• Ability to manage multiple providers and competing priorities in a dynamic, fast-moving environment.
• Self-motivated and effective working independently in a remote setting, taking ownership and driving issues to closure without close supervision.
• Ability to work at launch sites and processing facilities, including cleanroom, hazardous-operation, and outdoor environments, and to work extended and irregular hours during launch campaigns.
• Ability to travel up to 20% to launch vehicle provider facilities, AST sites, customer meetings, and non-Florida launch sites, including for extended campaign support.
• Ability to obtain and maintain access to Cape Canaveral Space Force Station and Kennedy Space Center.
• U.S. person status required for access to export-controlled launch vehicle data.
• Dedicated home office and reliable internet required; the remote position must be based within commuting distance of Cape Canaveral, Florida.

Nice To Haves

• Experience with multiple launch vehicles or launch providers.
• Experience serving as launch site or campaign technical lead for a spacecraft or large constellation.
• Familiarity with range safety processes and requirements, such as SSCMAN 91-710, and launch site facilities at Cape Canaveral Space Force Station and Kennedy Space Center.
• Familiarity with CAD viewing tools and structural and thermal analysis outputs, including coupled loads analysis.

Responsibilities

• Serve as the lead technical interface between AST and launch vehicle providers, representing AST in technical interchange meetings, working groups, and mission integration reviews.
• Act as AST’s technical authority at the launch site, leading spacecraft processing, integration, and encapsulation.
• Own, negotiate, and maintain spacecraft-to-launch-vehicle Interface Control Documents (ICDs) and related interface requirements, managing changes through formal configuration control.
• Lead launch vehicle compatibility and coordinate integration analyses, including mass properties, structural loads and coupled loads analysis, environments, thermal, RF, electrical, and separation and deployment.
• Define and track launch-related requirements, verification plans, and mission assurance deliverables, ensuring launch vehicle requirements flow down into spacecraft and ground design.
• Support launch vehicle provider evaluation and selection, including technical assessments and trade studies.
• Lead launch operations with launch vehicle, range, and facility teams.
• Lead technical launch readiness reviews and provide go/no-go technical recommendations to AST leadership.
