Mechanical CAD Designer

Mechanical CAD Designer Requisition ID: ASKUSR0147202 Location: Berkeley, CA | Primarily onsite at Lawrence Berkeley National Laboratory Pay Rate: $73.00 per hour Anticipated Assignment: November 2, 2026–October 29, 2027, with a potential additional one-year option subject to customer approval, project needs, funding, and performance. About Essnova Solutions At Essnova Solutions, Inc., we connect talented professionals with meaningful work supporting government and scientific missions. We value collaboration, thoughtful problem-solving, and the expertise each person brings to the team. Join us in supporting engineering work that helps advance groundbreaking research. About the Role Essnova 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 Responsibilities Create 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. Required Qualifications Knowledge or experience equivalent to a bachelor’s-degree level in mechanical design, engineering technology, drafting/design, or a closely related specialty, including equivalent computer-aided drafting experience. At least five years of current or recent professional experience using PTC Creo Parametric , formerly Pro/ENGINEER/Wildfire, for mechanical CAD design. Demonstrated ability to build and manage complex assemblies, understand parent-child relationships, and apply advanced Creo modeling methods. Experience producing manufacturing-ready Creo drawing packages that include GD&T, multi-sheet assembly drawings, detailed fabrication drawings, and bills of materials . Significant technical expertise in mechanical engineering principles and practices, including translating functional requirements into technical designs and evaluating alternatives within schedule, cost, and material limitations. Ability to collaborate effectively with engineers, scientists, and project teams. Strong verbal and written communication skills, accurate technical documentation practices, and the ability to meet task schedules and technical performance requirements. Preferred Qualifications Experience supporting DOE national laboratories, research facilities, particle accelerators, or other complex scientific or industrial engineering projects. Experience with Windchill or another Product Lifecycle Management/Product Data Management system. Experience supporting synchrotron or beamline design activities. Experience supporting fabrication, assembly, installation, or commissioning of complex engineered systems.11366666666663292 #J-18808-Ljbffr
