 * Experience supporting system level technical reviews and coordinating across multi-disciplinary engineering teams
 * Flight test or field test experience supporting system-level evaluation and data analysis
 * Active and transferable U.S. government issued Secret security clearance is required prior to start date. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance

Qualifications We Prefer:

 * Experience defining system architectures, performance budgets, and interface definitions
 * Model-Based Systems Engineering (MBSE) tools (e.g., Cameo)
 * Agile development tools and workflows (e.g., Jira, Confluence)
 * MATLAB, Ada, C/C++, or DOORS
 * Experience supporting integration, verification, or test activities for complex systems

 * Experience preparing technical documentation or delivering system-level technical outputs to stakeholders

## Description

Raytheon's Systems Engineering and Test Capabilities (SE&TC) Systems Engineering is seeking a Lead Systems Engineer for QRC2 where you'll serve as the technical lead driving complex EO/IR solutions from concept through deployment. In this highly visible role, you'll shape system architecture, lead requirements and integration efforts, collaborate directly with customers, and guide multidisciplinary teams through the full systems engineering lifecycle. This is an On-Site position located in McKinney, Texas.

What You Will Do:

 * Serve as the Lead Systems Engineer focal point for the program
 * Lead the definition, development, and implementation of system architectures, algorithms, and interfaces for EOIR capabilities.
 * Manage configuration process, performs functional analysis, timeline analysis, detail trade studies, requirements allocation and interface definition studies to translate customer requirements into hardware and software specifications
 * Partner with the Program Chief Engineer in ensuring the engineering team aligns to cost/schedule
 * Provide technical directions to multi-disciplinary program teams
Implement and ensure adherence to systems engineering processes throughout the program lifecycle

 * Oversee the development and maintenance of technical documentation, including system specifications, design documents, and test plans
 * Coordinate system engineering activities, including requirements analysis, system design, integration, and testing
 * Conduct system level trade studies and performance analysis
 * Participate in design reviews, technical meetings, and customer presentations
Support program management with technical risk assessments and mitigation strategies

 * Ensure the logical and systematic conversion of product requirements into total systems solutions that acknowledge technical, schedule, and cost constraints.
 * Decomposes customer specifications and system level requirements into sub-system and piece part requirements and generates verification criteria and plans for the requirements
 * Champion systems engineering best practices and ensure adherence to established engineering processes across the program lifecycle
