About the role

Introduction ASML US, including its affiliates and subsidiaries, bring together the most creative minds in science and technology to develop lithography machines that are key to producing faster, cheaper, more energy-efficient microchips.

We design, develop, integrate, market and service these advanced machines, which enable our customers - the world's leading chipmakers - to reduce the size and increase the functionality of their microchips, which in turn leads to smaller, more powerful consumer electronics.

Our headquarters are in Veldhoven, Netherlands and we have 18 office locations around the United States including main offices in Chandler, Arizona, San Jose and San Diego, California, Wilton, Connecticut, and Hillsboro, Oregon. Job Mission ASML's Wafer Alignment Sensor department in Wilton CT is seeking a Design Engineer to support and develop complex optical/photonic sensor systems used within ASML's photolithography tools.

These systems typically include light sources, detectors, optical/electro-optical components, fiber optics, electronics and signal processing software functioning in close collaboration with the rest of the lithography system. As a design engineer, you will design, develop, build and integrate optical sensor systems.

This position may require access to controlled technology, as defined in the Export Administration Regulations (15 C.F.R. § 730, et seq.). As a condition of employment, qualified candidates must be legally authorized to access such controlled technology prior to beginning work. Business demands may require the Company to proceed with candidates who are immediately eligible to access controlled technology.

Role and Responsibilities Use general Physics, Optics, Software knowledge and an understanding of the sensor systems and tools to develop optical alignment sensors in lithography machines Have hands-on skills of building optical systems (e.g. imaging, testing, alignment, detector system, etc.)

Have strong data analysis skills to evaluate sensor performance and troubleshooting Leadership Lead executing activities for determining problem root cause, execute complex tests, gather data, and effectively communicate results on different levels of abstraction (from technical colleagues to high level managers) Lead engineers in various competencies, eg software, electronics, equipment engineering, manufacturing engineering in support of feature delivery for alignment sensors Problem Solving Troubleshooting complex technical problems Develop/debug data signal processing algorithms Develop and execute test plans in order to determine problem root cause Communications/Teamwork Good communication skills during brainstorm/troubleshooting sessions Good listening skills Good analytical skills Draw conclusions based on the input from different stakeholders Capability to clearly communicate the information on different level of abstraction Programming Implement data analysis techniques into functioning MATLAB codes Optimization skills GUI building experience Familiarly with LabView and Python Some travel (up to 10%) to Europe, Asia and within the US can be expected Scope / Level of Impact JG07: Leads complex technical design work within a discipline or owns a module-level area requiring input from multiple engineers.

Works autonomously on complex assignments and interfaces with suppliers or customers as part of a broader team. JG08: Leads development of complex parts of modules, owns technically complex solutions, considers industrialization and cross-team impact, and may guide a small group of peers through technical execution.

JG09: Takes full technical ownership of multiple complex designs end-to-end, manages system impacts and cross-functional dependencies, and drives solutions through significant technical uncertainty. Education and Experience JG07: BS degree in a technical field and 2+ years of solid experience; MS preferred.

The current base annual salary range for this role is currently: $93,750 - $137,000 JG08: BS degree in a technical field and 5+ years of thorough experience; MS or PhD preferred.
