Collins Aerospace is seeking a Principal Materials & Process Specialist to serve as a technical leader and subject matter expert (SME) in supplier manufacturing compliance, special processes, advanced materials evaluations, and REACH activities. This position requires broad expertise across metallurgy, chemical/materials science, and manufacturing processes, with the ability to assess both metallurgical and chemical process-related risks while providing support across the Materials team.

The Principal Materials & Process Specialist will lead complex supplier reviews, evaluate critical manufacturing and chemical/thermal processes, support compliance with REACH and other regulatory frameworks, and provide technical guidance to internal teams, leadership, and customers. The role will also define best practices for materials process reviews, mentor less experienced engineers, and may support other activities depending on business needs. This position may require up to 10% travel.

This position will sit at our Aguadilla, PR location. You must be residing in Puerto Rico at the time of starting employment. Relocation is not offered.

This role is categorized as hybrid, with 3 days onsite and 2 days remote following the schedule assigned by the Manager.

What YOU will do:

• Conduct comprehensive reviews of supplier processes, including forging, machining, heat treatment, surface finishing/plating, chemical processing, coating operations, and material certifications.
• Evaluate detailed materials and metallurgical data, such as hardness, tensile properties, chemical composition, grain flow, microstructures, coating quality, and surface chemistry for compliance with requirements.
• Assess supplier special processes using digital records, process data, chemical process parameters, and thermal/chemical modeling outputs.
• Apply engineering fundamentals and chemical reaction or thermodynamic modeling to evaluate process capability and compliance risks.
• Provide support for REACH compliance and other regulatory activities, including evaluating materials and processes to ensure conformity with environmental and safety standards.
• Summarize findings and prepare technical reports and presentations for leadership and customer-facing engagements.
• Provide technical guidance to suppliers to resolve compliance gaps and recommend process and documentation improvements.
• Collaborate with design, quality, and materials engineering teams to interpret specifications, align process requirements, and resolve technical questions.
• Develop, maintain, and continuously improve internal standards, review methodologies, and process compliance tools.
• Mentor and support engineers performing MPS reviews with leadership and deep subject matter expertise.

What YOU will learn:

• You will learn about our growing engineering team in Puerto Rico; What we do? Who we support? How we work?
