Original job description

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’re looking for a Principal Systems Engineer - Software to lead the definition, decomposition, and management of software requirements across a complex communications platform. You’ll work at the intersection of software, networking, infrastructure, and systems engineering, turning high-level stakeholder needs into clear, testable, and traceable software requirements that engineering teams can successfully implement.

This is a senior technical leadership role responsible for driving requirements excellence throughout the system lifecycle. You will partner closely with software, hardware, network, systems, and test engineering teams to ensure requirements are properly defined, reviewed, verified, validated, and maintained from concept through deployment.

The ideal candidate brings deep systems engineering expertise, strong communications software knowledge, and a proven ability to lead the development of large-scale, highly integrated technical systems.

Key Responsibilities

Lead development of software system requirements from stakeholder needs and system-level concepts through subsystem and component-level specifications
Define and maintain software requirements for communications software, networking functions, interfaces, and distributed system architectures
Develop and manage interface control documents (ICDs) between software elements, infrastructure components, external systems, and partner interfaces
Own requirements traceability from stakeholder needs through design, implementation, verification, validation, and operational acceptance
Lead requirements reviews and drive resolution of ambiguity, conflicts, risks, and gaps across engineering disciplines
Conduct system-level trade studies and technical analyses to support architecture and requirements decisions
Partner with software development and test teams to define verification strategies, acceptance criteria, and validation approaches
Support system integration activities, anomaly investigations, root-cause analysis, and requirements changes throughout the development lifecycle
Develop and maintain requirements management processes, standards, and best practices
Collaborate with internal and external stakeholders to ensure technical requirements align with business and operational objectives
Mentor engineers and promote strong systems engineering principles across the organization
Provide technical leadership on complex system architecture, integration, and requirements management initiatives

Experience working throughout the systems engineering lifecycle, including requirements analysis, design support, verification, validation, and deployment
Experience using requirements management, configuration management, and traceability processes in complex engineering environments

Preferred Qualifications:

Experience within cellular telecommunications, wireless communications, networking, or related communications technologies
Familiarity with 4G LTE, 5G, radio access networks, core networks, IMS, or related telecommunications architectures
Knowledge of industry standards and specifications development processes
Experience supporting satellite communications, space systems, or non-terrestrial network architectures
Experience with Model-Based Systems Engineering (MBSE)
Experience using SysML, Cameo, or similar MBSE tools
