## Description

We are seeking an experienced Principal Systems Engineer to provide technical leadership for the design, development, integration, test, verification, and sustainment of advanced space systems and satellite technologies. This individual will play a critical role in shaping system architecture, driving cross-functional engineering efforts, and leading the successful execution of complex aerospace and defense programs from concept development through mission deployment and operations. The ideal candidate combines strong systems engineering expertise with hands-on technical experience across electrical, mechanical, software, and spacecraft subsystems. This role requires a strategic thinker who can effectively lead multidisciplinary teams while remaining engaged in the technical details that drive mission success.
Responsibilities

 * Lead the full systems engineering lifecycle including requirements development, architecture definition, interface management, integration, verification, validation, and mission readiness activities.
 * Develop and maintain system requirements, specifications, Interface Control Documents (ICDs), verification matrices, and technical data packages.
 * Establish system architectures and technical solutions for spacecraft, payloads, ground systems, and mission operations.
 * Support the design, development, assembly, integration, testing, and deployment of satellite systems and related technologies.
 * Lead system-level trade studies and technical assessments to optimize performance, reliability, cost, and schedule objectives.
 * Oversee subsystem integration efforts spanning electrical power systems, communications, avionics, structures, propulsion, software, and payload technologies.
 * Provide technical direction and mentorship to engineers across multiple disciplines.
 * Serve as the primary technical authority for system-level decisions, risk management, and engineering problem resolution.
 * Drive engineering reviews including SRR, PDR, CDR, TRR, FRR, and mission readiness assessments.
 * Develop and execute integration, qualification, acceptance, and environmental test strategies for flight and ground hardware.
 * Lead anomaly investigations, root cause analysis efforts, and corrective action implementation.
 * Ensure traceability between requirements, verification activities, and mission performance objectives.
 * Evaluate emerging technologies and lead research initiatives focused on next-generation spacecraft and mission capabilities.
 * Support rapid prototyping, technology maturation, and transition of innovative concepts into operational systems.
 * Collaborate with internal and external stakeholders, customers, and mission partners to advance program objectives.
 * Maintain accurate engineering documentation throughout the program lifecycle.
 * Present technical information to executive leadership, customers, partners, and review boards.
 * Ensure effective communication across cross-functional teams in a fast-paced development environment.
