About The Position

Delart is hiring a mid-to-senior mechanical design engineer for a hardware team developing autonomous vehicle and robotics systems in Sunnyvale, California. The role designs metal structures, sensor brackets, and electronics enclosures, ranging from small PCBA housings with heat sinks to large structural enclosures, and takes designs from 3D CAD through released 2D drawings. Structural and thermal judgment are important alongside CAD capability. This is a long-term contract position. The designer develops electronics and sensor enclosures, mostly from sheet metal, machined parts, or castings, with some plastic parts. The role also designs PCBA enclosures, heat sinks, and thermal paths at the box level; sensor brackets and mounts; and designs that withstand vibration, shock, and thermal loads. Designs are checked using hand calculations and structural and thermal FEA, then revised as needed. The designer creates 3D parts and assemblies, releases production drawings with GD&T to ASME Y14.5, and works with mechanical, electrical, and test engineers while maintaining clean CAD data, revisions, and documentation.

Requirements

At least 5 years of experience designing mechanical hardware, such as enclosures, brackets, or structures, that reached production.
Hands-on structural and thermal design experience, including sizing parts for loads and stiffness and designing heat paths and heat sinks for electronics.
Strong 3D CAD and 2D drawing skills with GD&T.
Design-for-manufacturing experience with sheet metal, machined parts, and castings, and some molded plastics.
Examples of past work that can be discussed in detail, such as a portfolio, drawings, or a design.

Nice To Haves

Advanced CATIA V5 or 3DEXPERIENCE experience, used daily.
Automotive, EV, autonomous vehicle, robotics, or drone hardware experience.
Experience with FEA tools such as ANSYS, Abaqus, or simulation tools built into CATIA, SolidWorks, or NX.
PLM experience with Enovia, 3DEXPERIENCE, or Teamcenter.
Test fixture design experience.
Comfort working from incomplete specifications at startup pace.
CATIA V5 or 3DEXPERIENCE is preferred; experts in SolidWorks, NX, or Creo will also be considered.

Responsibilities

Design small and large enclosures for electronics and sensor hardware, primarily using sheet metal, machined parts, and castings, with some plastic components.
Design PCBA enclosures with heat sinks and thermal paths to keep electronics within temperature limits.
Design sensor brackets and mounts that maintain alignment under vibration, shock, and thermal loads.
Evaluate designs with hand calculations and structural and thermal FEA, and revise designs based on findings.
Build 3D parts and assemblies and release 2D production drawings with GD&T to ASME Y14.5.
Collaborate with mechanical, electrical, and test engineers.
Maintain CAD data, revisions, and documentation.
