Explore Principal Metrology Engineer jobs and discover a pivotal senior-level career at the intersection of precision engineering, quality assurance, and advanced manufacturing. A Principal Metrology Engineer is a technical leader and subject matter expert responsible for the entire measurement science framework within an organization, typically in high-stakes industries like aerospace, automotive, semiconductor, and medical devices. This role transcends routine inspection; it involves architecting, validating, and governing the metrology systems that ensure products are built to exact design specifications, performance standards, and regulatory requirements. Professionals in these jobs are the strategic architects of measurement. Common responsibilities include developing and overseeing the corporate metrology program, defining quality requirements, and establishing process controls. They lead the selection, deployment, and calibration of sophisticated measurement equipment such as Coordinate Measuring Machines (CMMs), laser trackers, optical scanners, and articulated arms. A core duty is creating and standardizing inspection plans and techniques, often employing a risk-based approach to focus on critical features and complex geometries. They execute and oversee verification processes, including detailed tolerance stack-up analyses and design reviews to ensure manufacturability. Furthermore, Principal Metrology Engineers play a crucial role in training and mentoring inspection teams, writing technical procedures, and driving continuous improvement in measurement accuracy and efficiency. Typical skills and requirements for these high-level jobs are extensive. A deep, practical knowledge of metrology software (e.g., PC-DMIS, Calypso, PolyWorks) and Geometric Dimensioning and Tolerancing (GD&T) is fundamental. Candidates usually possess 10+ years of progressive experience in a manufacturing or R&D environment, with a proven track record in a highly regulated sector. Expertise in model-based engineering and experience with quality management standards like AS9100 or ISO 9001 are common prerequisites. Beyond technical prowess, success demands strong leadership, project management, and cross-functional collaboration skills to influence design and manufacturing teams, integrating quality and precision into every phase of the product lifecycle. For those seeking to lead the science of measurement and ensure unparalleled product integrity, Principal Metrology Engineer jobs represent the apex of a technical quality career.
