Introduction: ASML brings together the most creative minds in science and technology to develop lithography systems that are key to producing faster, cheaper, more energy-efficient microchips. As a Mechatronics Engineer in Wilton, you will specify, design, develop, realize, integrate, and test modules, tools, and system-level solutions in close collaboration with cross-functional teams, suppliers, and internal stakeholders. Role and Responsibilities: In this role, you will contribute to mechatronics engineering deliverables that scale by job grade, from executing defined technical work to leading complex module development, shaping technical direction, and driving system-level integration across multiple designs. Identify, analyze, document, and manage technical requirements, including traceability and verification criteria. Develop engineering concepts, design solutions, and technical tradeoffs to meet performance, cost, schedule, safety, and compliance needs. Define specifications and high-level designs, align interfaces, and support design reviews and approvals. Support system and product integration by coordinating dependencies, managing configuration needs, and enabling smooth execution across functions. Plan and execute verification and validation activities, improve test methods, and ensure qualification evidence supports release readiness. Estimate effort, plan and track work, manage risks and dependencies, and deliver assigned work packages or projects to agreed quality and timelines. Maintain accurate technical documentation, share knowledge, coach or mentor others as appropriate for the role level, and follow EHS policies while identifying and mitigating safety risks. Skills: Technical and Functional Skills Requirements, interfaces, and technical specification management: Ability to identify, analyze, document, and manage requirements with traceability, translate them into clear specifications, and align interfaces for reliable downstream design, integration, and verification. Engineering solution development: Ability to develop mechatronics concepts and solutions, make sound technical tradeoffs, resolve issues, and realize designs that meet functionality, performance, cost, compliance, and schedule constraints, including a deep understanding of control theory, structural dynamics, mechanical design and vibrational analysis. Integration, verification, and validation: Ability to plan and execute verification and validation, ensure qualification evidence supports release readiness, and coordinate dependencies to deliver working, testable solutions. Behavioral and Leadership Skills Drives results by translating technical goals into clear priorities, execution plans, and measurable outcomes. Demonstrates self-awareness by seeking feedback, adapting behavior, and improving collaboration in complex environments. Values differences by seeking and integrating diverse perspectives and working styles. Builds effective teams by establishing clear goals, roles, ways of working, trust, and accountability. Drives vision and purpose by communicating direction, aligning people on priorities, and sustaining focus through ambiguity and change. Other Information: This position is based on-site in Wilton, CT. May require domestic and/or international travel up to 10%, depending on business needs. Role may involve routine sitting, walking, talking, hearing, keyboard use, reaching, stretching, and occasional movement around campus. Occasionally required to lift and/or move up to 20 pounds. Specific vision abilities may include close vision, color vision, peripheral vision, depth perception, and ability to adjust focus. There is potential for exposure to strong magnetic fields, high voltage, and currents. Additional Responsibilities:: There is potential for exposure to strong magnetic fields, high voltage and currents. This position requires access to controlled technology, as defined in the United States 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. Business demands may require ASML to proceed with candidates who are immediately eligible to access controlled technology.
