Mechanical Engineer, AI Integration

Xometry is seeking a talented Mechanical Engineer to join our Generative AI and Geometric Integration team. In this role, you will apply your foundational knowledge of mechanical design, manufacturing processes, and 3D CAD data to support high-stakes strategic initiatives—specifically DFM AI + IQE integration. Working closely with our Data Science and Product teams, you will act as a hands-on domain expert to translate physical manufacturing constraints, 2D technical drawings, and 3D geometry into structured inputs that train and improve Xometry’s proprietary AI engine. This position bridges the gap between traditional mechanical engineering and modern software automation, helping build a real-time digital thread directly inside our partner’s ecosystem (NX, Designcenter, and Teamcenter). This role requires a hybrid schedule (3 days a week) at our Waltham, MA or North Bethesda, MD office location.

Responsibilities

Analyze native 3D CAD models to identify complex geometric topologies, specific features, and GD&T annotations; Assist in testing and validating real-time manufacturability (DFM) and pricing feedback loops embedded within Siemens NX and Teamcenter workflows; Provide ground-truth engineering logic to Data Scientists and Machine Learning engineers for training Generative AI models; Create, review, and structured-label datasets from 2D technical drawings, PDFs, and purchase orders; Document and map standardized manufacturing constraints across processes into discrete rules for software consumption; Conduct regression testing on software outputs comparing AI-generated pricing and lead times against real-world manufacturing metrics; Act as technical point of contact across internal engineering, operations, and external partner development tracks

Requirements

2-5+ years of hands-on experience in mechanical design, manufacturing engineering, or a closely related industrial environment; Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, or a related technical discipline; Solid working knowledge of enterprise CAD/PLM systems; Strong foundational understanding of standard manufacturing methods, particularly multi-axis CNC milling/turning and sheet metal fabrication; Ability to interpret ASME Y14.5 GD&T prints; Strong capability to communicate technical engineering concepts clearly to non-mechanical peers; High attention to detail; Strong spatial reasoning; Agile mindset comfortable with rapid experimentation and iterating

Nice to have

Direct experience using Siemens NX and Teamcenter; Basic proficiency in Python or a strong willingness to learn it for automated data analysis and geometric manipulation

Benefits

401(k) match; medical, dental and vision insurance; life and disability insurance; generous paid time off including vacation, sick leave, floating and fixed holidays, maternity and bonding leave; EAP and other wellbeing resources
