About the role
As a Senior Mechanical Engineer at MKS Instruments on the Irvine Central Mechanical Engineering Team, you will plan, conceptualize, design, document, procure, and test high-precision opto-mechanical products, tooling, and fixtures. The role supports the design and documentation of products for the semiconductor fabrication industry and delivers fixturing used to manufacture precision optics and optical assemblies.
What you'll do
- Utilize NX and SolidWorks to analyze, design, and document mechanical systems, equipment, fixturing, and packaging.
- Conduct feasibility studies and test new and modified designs, including RSS tolerance analysis and FEA.
- Design, model, procure, assemble, and validate optical-mechanical fixturing and tooling for production equipment.
- Manage multiple projects across product design, fabrication, cleaning, coating, and testing of optics and opto-mechanical assemblies.
- Update CAD drawings, submit Engineering Change Orders (ECOs), and lead design reviews from definition to implementation.
What you'll need
- Bachelor of Science in Engineering degree.
- 5 or more years of related experience designing tooling, fixtures, or systems incorporating repeatable precision mechanisms.
- Proficiency with NX and SolidWorks CAD software as design and documentation tools.
- Familiarity with metal fabrication methods including CNC, lathe, and EDM.
- Ability to perform tolerance analysis to verify the fit and function of designs.
- Familiarity with product life cycle management, including product development processes and ECO processes.
Nice to have
- Experience with laser systems, optical components, and optics mounting in a production environment.
- Working knowledge of FEA, with experience in ANSYS, PDMWorks vault, SolidWorks PDM vault, or ZEMAX.
- Familiarity with motion control, optical power generation, and detection instrumentation.
- Experience with complex high-precision opto-mechanical components.
- Experience with Agile, SAP, or DFMEA risk assessment and mitigations.
- Master of Science degree or equivalent advanced training.

How we counted: 1150 open Hardware Systems Engineering (AI ML Hardware) roles from 109 employers tracked in the SemiconductorJobs index, counted 11 Nov 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there, and is counted in the wider Software, Firmware & Systems family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
