Civil Engineer

AST Space Mobile 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.

Lead civil and structural assessments for satellite gateway sites, ensuring that foundations, site layouts, utilities, and construction work meet engineering expectations, local permitting requirements, and overall deployment timelines.

You will own the civil scope from site survey and design review through construction quality, issue resolution, and final turnover, ensuring the site is fully ready for gateway activation.

This role operates at the intersection of civil engineering excellence and satellite technology deployment, requiring engineering precision balanced with business urgency while managing regulatory requirements across diverse markets.

• Conduct civil surveys to understand topography, access, drainage patterns, soil behaviour, utilities, and overall build feasibility
• Identify risks related to site conditions early to support reliable design and construction planning

• Review designs for foundations, antenna/radome supports, equipment pads, shelters, structural frames, and site steel
• Confirm that designs account for expected forces such as wind and seismic and follow widely used US design practices common to building and telecom infrastructure
• Ensure designs are ready for local permitting by aligning with widely adopted building‑safety requirements used across US jurisdictions

• Prepare civil/structural drawings and calculation packages in a format suitable for local building departments
• Coordinate with Authorities Having Jurisdiction (AHJs) to help obtain timely permits
• Support environmental and construction‑site compliance requirements such as stormwater control, erosion control, and proper site‑runoff management (standard requirements for most US construction projects)

• Oversee construction activities including earthworks, foundations, drainage works, trenches and duct banks, and concrete installations
• Ensure contractors maintain proper stormwater controls and follow good environmental practices on site
• Address onsite technical issues such as RFIs, unexpected soil or rock conditions, and field adjustments
• Support safe lifting plans and heavy‑equipment activities, especially for antennas and large components, following widely accepted construction‑safety practices

• Ensure all civil deliverables as‑built drawings, inspection results, soil and concrete test records, redlines, and turnover documentation are complete and accurate
• Identify when tall structures or temporary cranes may require review by aviation authorities and coordinate the necessary documentation
• Prepare the site so it is fully ready for installation of gateway antenna systems, power systems, and related infrastructure

• Work closely with teams including RF/antenna engineering, mechanical and electrical teams, operations, HSE, program management, procurement, legal/permitting, and real estate/site acquisition
• Coordinate with electrical/MEP teams on grounding and lightning‑protection elements, ensuring civil interfaces are properly addressed

• Bachelor's degree in civil engineering or related field
• 5+ years of experience in civil/structural engineering for mission‑critical, telecom, industrial, or similar infrastructure
• Ability to review civil/structural designs for conformance with commonly used US building and structural design practices
• Construction experience including QA/QC, inspection oversight, RFI management, and closeout documentation
• Familiarity with construction stormwater and erosion‑control requirements typically required on US projects
• Abil…
