Staff Mechanical Engineer

Company: Onto Innovation
Location: Milpitas
Posted on: August 2, 2022

Job Description:

Onto Innovation is a leader in process control, combining global scale with an expanded portfolio of leading-edge technologies that include: 3D metrology spanning the chip from nanometer-scale transistors to micron-level die-interconnects; macro defect inspection of wafers and packages; metal interconnect composition; factory analytics; and lithography for advanced semiconductor packaging. Our breadth of offerings across the entire semiconductor value chain helps our customers solve their most difficult yield, device performance, quality, and reliability issues. Onto Innovation strives to optimize customers' critical path of progress by making them smarter, faster and more efficient.
Job Summary & ResponsibilitiesOnto Innovation is seeking an experienced Mechanical Engineer with expertise in motion control to support the R&D team. Gearheads, makers, and hands on craftsmen with a high tech thinking cap desired. This is a great position for someone truly passionate about mechatronics and precision engineering. If you love Wayne Moore's book, "Foundations of Mechanical Accuracy" this job is for you. We are looking for the kind of engineer that plans for the manufacturing process, thinks about how the welder is going to get a torch down into that hard to reach corner, knows the appropriate machine tool his parts should be manufactured on and their capabilities, and understands when, and how to apply GD&T, but designs systems that tolerate applying it sparingly. Bonus points for disciples of Carroll Smith.
The engineer will be responsible for developing hardware and tooling concepts, performing detailed design calculations and analyses, performing detailed design of optical mounts, sub-micron precision adjustment, and positioning mechanisms, assembly, and test of prototype systems, and finalizing the design through product release for current and future metrology instruments. Depending on the size and scope of the project, this work may be done by the engineer alone, or by a small team of engineers and designers.
