About The Position

Collins Aerospace is seeking a Principal Systems Engineer to serve as a technical leader and subject matter expert (SME) in Model-Based Systems Engineering (MBSE), embedded control systems, and system‑level architecture and requirements development. This role requires broad expertise in aerospace systems, safety‑critical development processes, systems architecture, requirements flow-down, modeling, simulation, and verification. The Principal Systems Engineer will lead complex system architecture efforts, guide MBSE methodologies, ensure compliance with aerospace standards, and provide technical mentorship to engineers across the organization. The position requires strong communication skills, cross‑functional collaboration, and the ability to evaluate technical risk across system interfaces and development phases. This role may require limited travel (up to 10%). 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.

Requirements

Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and 8 years prior relevant experience or an Advanced Degree in a related field and minimum 5 years of experience.
Demonstrated professional experience communicating in English across all levels of an organization (verbal and written).
Demonstrated experience with modeling, simulation, and system analysis.
Experience leading electronic or embedded system design and development.
Strong stakeholder management and cross‑functional leadership skills.
Experience developing system architectures and system requirements for aerospace or safety‑critical products.
U.S. citizenship is required, as only U.S. citizens are authorized to access information under this program/contract.
