Senior Mechanical Engineer – Electronics Packaging

ASML is looking for a Senior Mechanical Engineer focused on Electronics Packaging to support the end-to-end creation of modules and tools. In a multi-disciplined environment, you will specify, design, develop, realize, integrate, and test deliverables while coordinating closely with cross-functional partners and suppliers from early feasibility through sustainment and customer issue resolution.

This onsite role in Wilton, CT involves owning technically complex scope across the product life cycle, including electrical infrastructure and enclosure design, validation and test execution, and technically leading interfaces where requirements and integration constraints evolve.

Role focus

• Specify, design, develop, realize, integrate, and test modules and tools as part of a multi-disciplined team.
• Deliver solutions that fit system specifications, cost targets, and project schedules.
• Provide discipline-specific expertise across the product life cycle, including concept feasibility, new product introduction, existing product sustainment, and customer-facing problem resolution.
• Lead development of complex parts within modules, with ownership that considers industrialization and cross-team impacts.
• Collaborate across multiple teams, lead interfaces with suppliers and other disciplines, and guide peers through technical execution.

Responsibilities

• Identify, analyze, document, and manage requirements with traceability; coordinate verification criteria to confirm deliverables meet intent.
• Conduct research and feasibility studies, document findings, and translate results into recommendations, tradeoffs, and decision inputs.
• Develop engineering concepts and solutions, make technical choices, and resolve issues to meet functionality, performance, cost, and compliance needs.
• Define and communicate specifications and high-level designs, align interfaces, and support reviews and approvals for quality execution.
• Support system or product integration by coordinating dependencies, applying configuration management, and enabling smooth project execution.
• Define and execute validation and test approaches; improve methods and procedures; ensure qualification evidence supports release of 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 through coaching and mentoring as applicable, and follow EHS policies while identifying and mitigating safety risks.

Core design and electrical infrastructure scope

• Design and document electrical infrastructure including AC/DC and main power distribution (panel boards, boxes, and cabinets).
• Design and document interconnect cables, bundles, connectors, and harnessing.
• Design and document electronic racks, cabinets, and control consoles.
• Support interfacing with printed circuit board designs.
• Design electronic enclosure assemblies and perform sheet metal design.
• Apply design-for-manufacturability (DFM) and develop assembly work instructions for low to medium volume products.
• Use 3D solid modeling for design conceptualization and realization (NX preferred).
• Support design fit check during integration and testing at the module, sub-system, and system level.
• Apply industry codes and standards (including NEC 70, NFPA 79, and Machine Tool Standards).
• Perform dimensional and tolerance analysis as needed, including knowledge of design drafting best practices and geometric dimensioning.

Test and integration scope

• Design, develop, and build product-specific test tooling.
• Execute Test Validation and Verification (V&V) of product requirements.
• Plan and execute component level testing and sub-module integration.
• Plan and execute module level and system level integration.
• Write and define test procedures and test reports.

Qualifications

• Bachelor's degree in Mechanical or Electrical Engineering (MS or PhD preferred).
• Minimum 4 years of relevant work experience.
• Ability to manage requirements with traceability, translate them into clear specifications, and align interfaces for reliable downstream design, integration, and verification.
• Ability to develop concepts, make technical tradeoffs, resolve issues, and realize designs meeting functionality, performance, cost, compliance, and schedule constraints within system/module specifications.
• Ability to plan and execute verification and validation, ensure qualification evidence supports release readiness, and support integration through disciplined configuration and traceability.
• Experience across electrical infrastructure design, flex and rigid PWB modeling (including volumes and critical part locations), and electronic enclosure assemblies.
• Knowledge and hands-on familiarity with wiring and schematic diagrams.
• FEA knowledge is a plus.
• Experience requirements aligned to technical writing for specifications, design decisions, test procedures, and test reports.

Technologies

• NX, 3D CAD, FEA, Teamcenter, SAP
• NEC 70, NFPA 79
• AC, DC

Benefits

• Medical, dental, vision, and basic life insurance
• 401k plan
