 * Experience working on prototype systems in a hands-on laboratory setting
 * New product development and support in the semiconductor space
 * Must be able to travel internationally to customer sites at least 20% of the time, with additional travel as business needs require.

## Description

The core responsibilities of the Senior Systems Engineer are to develop new optical metrology technologies, to optimize the performance of existing metrology products, and to communicate those optimization results and methods to the field. The successful candidate will interface with cross functional engineering teams, e.g. software, hardware, and applications scientists, to generate specifications and performance requirements that guide systems development. They will also design and perform experiments that validate those requirements have been met and provide guidance on implementation improvements where needed. Additional responsibilities include support for on site installation of first in fab metrology tools, initial tool matching efforts of those systems, and the generation of procedures and training documents to educate local engineering teams. This will require international travel of <20%.

Roles & Responsibilities

 * Alignment, optimization, and validation of complex optical systems
 * Development of best operational methods for tool performance optimization
 * Design and conduct experiments to characterize, troubleshoot, and improve optical metrology systems
 * Develop plans of action, and execute in a timely manner
 * Generate both internal and external technical presentations
 * Clearly communicate requirements and specifications to cross functional teams
