Collins Aerospace is seeking a Senior Mechanical Project Engineer to join our team, where you’ll play a key role in designing and delivering the next generation of advanced aerospace, space, and undersea systems. In this role, you’ll bring your expertise in mechanical design, analytics, and project leadership to life—driving projects from concept through production while ensuring compliance with the highest performance, reliability, and safety standards. From rotating machinery and turbines to flight surfaces, pumps, and electronics packaging, your work will directly shape critical technologies that keep people safe and connected around the globe.

As part of a world-class engineering organization, you’ll take ownership of complex projects, lead multi-disciplinary collaboration, and apply cutting-edge tools like NX, ANSYS, and Model-Based Design practices to solve tough challenges. This position offers the opportunity to stretch your technical skills, mentor others, and have a lasting impact on products that matter. If you’re looking to combine your engineering expertise with project leadership in a role that drives innovation across Collins Aerospace, this is the opportunity for you.

What You Will Do:

• Lead and contribute to the design, modeling, and packaging of mechanical and electromechanical systems (e.g., rotating machinery, turbines, pumps, gearboxes, flight surfaces, and electronics packaging), generating drawings, specifications, analyses, and technical documentation throughout the product lifecycle.
• Plan and execute development, acceptance, and qualification testing; define and implement design changes; and support verification, validation, and field issue resolution.
• Drive multi-discipline mechanical analysis, building models, loads, and boundary conditions to support aerospace, space, and undersea applications.
• Apply and advance Model-Based Design (MBD) practices across engineering, fostering knowledge-sharing in design and processing with metals, composites, and non-metallic materials.
• Manage projects aligned with your expertise, take on stretch assignments for larger efforts, and support proposals with system designs, BOMs, and cost/schedule estimates.
• Partner with vendors and cross-functional teams to ensure product quality, vendor qualification, issue resolution, and successful product acceptance.
• Lead or support Relentless Root Cause Corrective Action (RRCCA) investigations, ensuring effective solutions to complex engineering problems.
• Work independently with minimal guidance while contributing to the development and improvement of departmental processes, standards, and work instructions.
