Reports to: Director of Management Operations

Quantum Computing Inc. (QCi) (Nasdaq: QUBT) is an innovative, integrated photonics company that provides accessible and affordable quantum machines to the world today. QCi products are designed to operate at room temperature and low power at an affordable cost. The Company's portfolio of core technology and products offer unique capabilities in the areas of high-performance computing, artificial intelligence, cyber security as well as remote sensing applications.

This position is responsible for overseeing the development of a 150 mm wafer line based on QCi's thin film lithium niobate (TELN) technology. The successful candidate will work in close collaboration with both the process development and integration team as well as the quantum optics team to develop and continuously improve high volume manufacturable metrology and test point processes for our TFLN products. These processes are designed to monitor line health, feed forward critical process and equipment data to optimize product yields, This candidate also plays a key role in facilitating short term SWAT teams when urgent line impacting defect investigations arise. The candidate will be responsible for designing, developing, deploying and optimizing metrology processes for measuring TFLN devices to achieve safety, quality, cost, and delivery goals for QCi and its customer products. The candidate will work closely with a team of process and equipment engineers and technicians to continuously improve their workflow with the goal of enhancing yield of TFLN devices and creating robust reliable manufacturing processes. Furthermore, the candidate will coordinate the factory metrology and diagnostic equipment calibration program.
