Principle Systems Engineering- Software

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
• Bachelor’s degree in Systems Engineering, Electrical Engineering, Computer Engineering, Computer Science, Software Engineering, or a related technical field
• Master’s degree in a related engineering discipline preferred
• Minimum 10–15 years of professional engineering experience
• Experience working as a Systems Engineer responsible for writing, managing, and maintaining requirements for complex technical systems
• Experience supporting large-scale software development, systems integration, or communications-based platforms
• Proven experience developing clear, concise, testable, and verifiable requirements
• 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
