About the Role

Collins Aerospace’s Resilient Connectivity Products (RCP) hardware team is seeking a determined and passionate Senior Mechanical Engineer with emphasis in manufacturing of electronics hardware to support our F16 Modular Mission Computer (MMC) programs in McKinney, TX. This engineer will serve as the Lead Mechanical Engineer as part of a cross-functional team, primarily focused on production and depot sustainment for the F16 MMC. This program provides a critical capability to our domestic and international allied warfighters—and this engineer will play a key role in supporting their readiness through commitment to technical excellence, leadership, and execution.

While the immediate focus is on an established production program, the RCP hardware team also develops next-generation Mission Systems. This role will have opportunities to contribute to new hardware design efforts, including obsolescence-driven redesigns and technology refresh initiatives.

Responsibilities

• Apply mechanical engineering principles and techniques to resolve production issues and maintain the qualified technical baseline for the F-16 MMC.
• Serve as the Lead Mechanical Engineer for the program's Mechanical team, managing daily tasks and priorities.
• Act as the primary Mechanical Engineer interface to Program Management, Chief Engineer, IPT leadership, Operations, and Supply Chain.
• Apply cost and schedule management methods to projects.
• Mentor early-career engineers and contribute to continuous improvement efforts.
• Perform mechanical analyses and validate design changes through review, integration, and test support—leveraging subject matter experts as needed.
• Collaborate across disciplines to ensure requirements are met throughout the product lifecycle, including integration, testing, qualification, production, and sustainment.
• Address obsolescence and supplier-driven changes, oversee supplier verification activities, evaluate non-conformances, and implement design/cost-saving improvements.

What You Will Learn

• Broaden your knowledge about tactical airborne processing systems and other various engineering disciplines.
• Gain depth in manufacturing of ruggedized electronics, including flex circuits, PWBs, CCAs, castings, metal fabrication, coatings, and finishes.
• Apply Design for Manufacturing (DFM) principles through close working experience with complex electronics assemblies.
• Take advantage of opportunities to excel professionally with RTX's exceptional employee scholar programs and continuing education.
• Build experience that has enabled past engineers in this role to advance into IPTLs, Analysts, Systems Engineers, Chief Engineers, Section Managers, Department Managers, and Directors across RTX.

Requirements

• Typically requires a degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 5 years of prior relevant experience, or an Advanced Degree in a related field and a minimum of 3 years of experience.
• Experience with electronic product packaging (Circuit Card Assemblies, Printed Wiring Boards, electronics chassis, etc.).
• Experience with Computer-Aided Design (CAD), including working knowledge of model creation and interrogation with CAD tools like PTC Creo (preferred), NX, or SolidWorks to support mechanical designs.

Preferred Qualifications

• Experience interfacing with internal and external suppliers (SOW generation, experience with RTX Operations/Supply Chain processes).
• Proven experience with machined and sheet metal manufacturing methodologies.
• Knowledge in design for low cost, manufacturability, and small-volume packaging.
• Experience with geometric dimensioning and tolerancing (GD&T).
• Familiarity with bid, proposal, and earned value methods.
• Experience with Finite Element Analysis (FEA) and/or Computational Fluid Dynamics (CFD) and associated analysis methodologies.
• Design experience.
• Lead Mechanical Engineering experience.

Benefits

• Medical, dental, and vision insurance.
• Three weeks of vacation for newly hired employees.
• Generous 401(k) plan that includes employer matching funds and separate employer retirement contribution, including a Lifetime Income Strategy option.
• Tuition reimbursement program.
