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 Mid-Level Systems Engineer to join our growing team. This role is designed for a versatile, engineer who can both lead and execute: stepping into project lead roles, driving technical budget development, shaping new concepts, and filling critical gaps across programs as business needs evolve.

The ideal candidate brings demonstrated SE lead experience from prior programs and thrives in a fast-paced, mission-driven environment where no two days look the same.

Key Responsibilities:

• Serve as Systems Engineer Lead on assigned programs, owning technical direction from requirements definition through verification and validation
• Develop, maintain, and track technical budgets (mass, power, link, schedule) across multiple subsystems.
• Lead the development of new mission concepts and system architectures in response to customer or internal needs.
• Translate high-level requirements into actionable subsystem and interface specifications.
• Coordinate across engineering disciplines (RF, software, mechanical, electrical) to drive system-level integration and resolve cross-cutting issues.
• Facilitate and participate in design reviews (SRR, PDR, CDR) and technical interchange meetings (TIMs).

Qualifications

Education:

Bachelor's degree in Systems Engineering, Aerospace Engineering, Electrical Engineering, or a related technical field required;

Experience:

A minimum of 7 years of systems engineering experience, with at least 2 years serving as an SE Lead on a program of record

Preferred Qualifications:

• Master's degree in a relevant engineering discipline.
• Experience in space, satellite, or defense programs.
• Experience with requirements management tools and configuration control processes.

Soft Skills:

• Strong interpersonal skills with proven ability to lead and influence across cross-functional teams.
• Excellent written and verbal communication skills, including ability to brief technical and executive audiences.
• Comfort operating in ambiguity — able to define the path forward when requirements are incomplete or roles are fluid.
• Strong analytical and problem-solving ability with meticulous attention to detail across documentation and deliverables.
• Ability to manage multiple competing priorities in a dynamic, fast-moving environment.
• Self-starter who takes ownership and drives issues to closure without close supervision.

Technology Stack:

• Microsoft Office Suite (Word, Excel, PowerPoint) for documentation, analysis, and reporting.
• Requirements management tools: DOORS, Jama, or equivalent.
• MATLAB / Simulink for analysis and trade studies (preferred).
• STK (Systems Tool Kit) for mission analysis (preferred).

Physical Requirements

• Ability to work in a standard office environment and use a computer for extended periods.
• Occasional travel to other AST SpaceMobile facilities or customer/government sites (up to 20%).
