Dimensional Metrology Quality Engineer

About OpenTrainOpenTrain is the centralized, open platform where AI training and data-labeling freelancers find work, consolidate opportunities across platforms, and build a unified AI training portfolio they control. We make specialized AI training work easier to track, apply for, and grow into a durable freelance career. About this roleOpenTrain is recruiting a Dimensional Metrology Quality Engineer to provide expert inspection and measurement input for AI system development. You will evaluate and produce first-article inspection deliverables using 3D scan data and advanced metrology software, with a focus on scan-to-CAD accuracy, datum structures, profile and position callouts, and sound dimensional reasoning. The work is suited to a contractor with practical manufacturing or quality experience who can make careful sign-off judgments and explain the evidence behind them. What you will doYou will review and validate first-article inspection reports derived from 3D scan data, conduct scan-to-CAD comparisons, and analyze the sources of measurement deviations. You will set up, interpret, and document datum structures, profiles, and position callouts according to industry standards. You will apply CMM measurement techniques and uncertainty analysis to assess dimensional integrity, distinguish genuine part deviations from artefacts introduced by fixturing or alignment, and provide clear written and verbal feedback that supports FAI sign-off decisions and high‐quality AI training inputs. Required skillsCandidates should have strong expertise in Geometric Dimensioning and Tolerancing and first‐article inspection processes, along with practical experience in manufacturing or quality environments, including producing or approving FAI reports. Proficiency with 3D scanning devices and inspection software such as PolyWorks, GOM Inspect, or similar tools is required. You should have strong knowledge of CMM measurement techniques and uncertainty analysis, the ability to interpret engineering drawings, CAD models, and technical specifications, analytical judgment for distinguishing true quality issues from measurement‐setup artefacts, and clear written and verbal communication with careful explanatory detail. Experience with AS9102 first articles, varied scan hardware, or CMM programming can further support the work. Why work with OpenTrainOpenTrain gives freelancers one place to manage AI training opportunities instead of rebuilding proof of work on every platform. A stronger OpenTrain profile helps you show credible experience, discover roles that match your skills, and turn AI training and data‐labeling work into a long‐term portfolio. Use calibration and metrology experience to write practical questions and assess AI‐generated technical responses. Remote U.
