Vacuum System Engineer - ASML

Introduction to the Job

ASML is seeking a Vacuum Systems Engineer to join our Wilton, Connecticut location in the Defectivity Module Delivery Unit (MDU). Within ASML, the Development and Engineering (D&E) sector is responsible for the specification and design of ASML products throughout a product lifecycle. The Defectivity MDU department is responsible for creating and maintaining the critical environment, including molecular and particle cleanliness, within the vacuum reticle modules inside cutting-edge Extreme Ultraviolet (EUV) lithography machines. As a Vacuum Systems Engineer, you will play a key role in enabling next-generation EUV lithography by creating contamination-free vacuum environments for some of the world's most advanced semiconductor manufacturing systems.

In this role, you will help model and design gas flow from atmosphere to deep vacuum, select appropriate materials, and design cleanliness processes that support vacuum-grade performance in scanner and test-rig environments. The solutions developed in this role directly impact wafer yield, machine availability, and customer productivity.

Scope / Level of Impact

JG08

Leads technically complex vacuum and gas-flow work packages, supports hardware projects and lead designers, owns defined architecture or subsystem deliverables, and drives cross-functional alignment with architects, projects, competences, customer support, and research partners. Focuses on ownership of subsystem-level vacuum and gas-flow solutions while developing broader architecture expertise across the Defectivity domain.

JG09

Takes full technical ownership for complex vacuum systems or gas-flow architectures, manages system impacts and cross-functional dependencies, drives resolution through technical uncertainty, and contributes standards, procedures, and evidence-based recommendations across ASML units. Identifies and mitigates risks that could impact customer performance and reliability. Serves as a recognized subject matter expert who influences vacuum and gas-flow strategy across projects, products, and ASML sites.

Role and Responsibilities

As a Vacuum Systems Engineer in the Defectivity group, you will work closely with Veldhoven machine conditioning architects, Defectivity MDU architects and leadership to specify vacuum systems and gas flows in scanners and test rigs. Partner with hardware project teams and lead designers to ensure vacuum and gas-flow requirements are successfully integrated throughout the product development lifecycle. Lead the ASML Wilton Engineer guild for machine conditioning architecture and vacuum systems competence onsite.

• Translate the overall system design into a gas-flow and vacuum architecture that meets system requirements.
