The Effector RF Design Team at Raytheon is seeking a talented and experienced Senior Principal Engineer to join our innovative and collaborative team in Tucson, AZ. This role offers a unique opportunity to lead the development of a guidance system for a new missile development program that incorporates an advanced RF/Radar subsystem. The selected candidate will lead a cross-functional and cross-discipline team of engineers through the design cycle for development and integration.

What You Will Do:

• Ensure the technical integrity of the Guidance Section (GS), including the development, validation, and integration of the Technical Data Package (TDP).
• Provide technical oversight for GS subsystem and component requirements, design, testing, and performance.
• Collaborate with and provide technical support to critical suppliers to ensure performance goals are met.
• Manage technical risks associated with the Guidance Section to ensure program success.
• Partner with the systems engineering team to capture accurate GS and component-level requirements.
• Work closely with the integration and test team to plan and execute GS acceptance and verification testing.
• Collaborate with the algorithm and signal processing team to align hardware capabilities with their requirements while clarifying hardware limitations.
• Coordinate with other GS teams and subject matter experts (SMEs) on related activities and shared program goals.
• Provide technical oversight and support for failure investigations related to GS components or subsystems.
• Lead and participate in component-level design and test reviews to ensure technical rigor.
• Work directly with suppliers and customers to procure, validate, and demonstrate hardware capabilities.
• Lead teams effectively by understanding team dynamics, leveraging strengths, and addressing skill gaps.
• Deliver high-quality results while consistently meeting or exceeding cost, schedule, and performance objectives.
• Communicate task status on complex technical issues and influence strategic planning across multiple teams, programs, and leadership levels, including customers.
• Proactively identify and take ownership of roles or tasks necessary to ensure the success of the business unit.
