Mechanical CAD Designer

Mechanical Cad DesignerEssnova Solutions is seeking an experienced Mechanical Cad Designer to support the Advanced Light Source Upgrade (ALS-U) Project at Lawrence Berkeley National Laboratory. You will turn engineering concepts into detailed mechanical models, complex assemblies, and manufacturing-ready drawing packages. Working closely with engineers, scientists, and project personnel, you will support the fabrication, assembly, and installation of systems for a major scientific facility upgrade.Key ResponsibilitiesCreate and maintain detailed three-dimensional mechanical part and assembly models using PTC Creo Parametric or other project-approved CAD software.Develop and refine mechanical designs that meet functional requirements while accounting for schedule, cost, materials, and integration constraints.Build and manage complex assemblies using parent-child relationships, patterns, sweeps and trajectories, simplified representations, and top-down design techniques.Prepare manufacturing- and assembly-ready drawing packages, including detailed fabrication drawings, multi-sheet assembly drawings, and bills of materials.Apply geometric dimensioning and tolerancing (GD&T) and project drafting standards to clearly communicate design intent.Collaborate with engineers, scientists, project managers, and other disciplines to resolve technical issues, evaluate design alternatives, and coordinate mechanical interfaces.Participate in design reviews and incorporate engineering feedback and approved changes into models and documentation.Maintain organized, revision-controlled models, drawings, libraries, and design files within Windchill or other designated engineering systems.Complete assigned work in accordance with project schedules, quality requirements, applicable standards, and LBNL engineering practices.Follow applicable site access, safety, security, cybersecurity, work control, and confidentiality requirements.
