Introduction to the job

Responsible for the hands on assembly, debug, and verification of electronics,electromechanical, mechanical, vacuum, high pressure gas, optical systems and prototypes in support of Research activities such as design, test, evaluation of existing and new products. Responsible for assembly, maintenance, operation, and upgrading all equipment including but not limited to test programs, oscilloscopes, signal generators, analyzers, meters, solder assembly tools, specialized test apparatus, and laser systems. Performs operational test and fault isolation on systems and equipment. Works from schematics, diagrams, written and verbal descriptions, layouts or defined plans to perform fabrication, modifications, testing, checkout and trouble-shooting functions.

This position requires access to controlled technology, as defined in the Export Administration Regulations (15 C.F.R. § 730, et seq.). Qualified candidates must be legally authorized to access such controlled technology prior to beginning work. These questions assist the Company in determining whether an individual qualifies for the position.Business demands may require ASML to proceed with candidates who are immediately eligible to access controlled technology.

Role and responsibilities

  • Builds electrical, optical, vacuum, high pressure gas and mechanical assemblies in strict accordance with procedures.
