What will you do?

As a Mechanical Engineer II, you will design and develop robust mechanical systems for high-performance applications. You will work as part of a team of creative, cross-disciplinary engineers to meet project and customer requirements, with exposure to a wide variety of systems across metrology, semiconductor equipment, and industrial automation. At Quartus, you will be involved in the entire project lifecycle, from concept and design to build, test, and integration.

Essential Job Functions:

• Design and develop precision mechanical assemblies and subsystems
• Select, specify, and integrate motion and automation components such as linear and rotary stages, hexapods, actuators, and sensors
• Design and build prototypes; create detailed drawings and instructions for production
• Support assembly, integration, and testing in the lab or at customer sites
• Perform risk and tolerance analyses and lead subsystem FMEAs
• Develop tolerance budgets and drive design decisions at the component and assembly level
• Perform structural and thermal analyses to validate designs
• Own technical documentation (models, CAD drawings, simulations, BOMs, etc.)
• Work directly with program managers and customers to define and flow down technical requirements
• Execute projects independently and as part of a multidisciplinary team of engineers and technicians
• Mentor junior engineers and contribute to design reviews

Location

Position is based in San Diego, CA with a hybrid schedule.*
*The hybrid work arrangement is subject to change based on business needs including but not limited to training, performance, or other operational requirements. Any physical location change may impact future employment.
