Senior Mechanical Analysis Engineer

Introduction of the job

As a Senior Mechanical Analysis Engineer, you will apply advanced analytical and numerical methods to predict and optimize complex opto-mechanical and electromechanical systems throughout feasibility, design, integration, qualification, and troubleshooting.

You will bring deep expertise in finite element methods, solid mechanics, structural dynamics, heat transfer, fluid dynamics, numerical methods, or Multiphysics simulation. You will develop models of appropriate fidelity, evaluate technical risks, correlate predictions with test data, and translate complex results into clear engineering recommendations.

This is a senior technical role requiring analytical rigor, sound judgment, autonomy, and collaborative leadership. You will build trusted relationships across disciplines, influence decisions through expertise and credibility, mentor others, and advance ASML’s analysis methods and capabilities.

Role and Responsibilities

• Translate system and module requirements into analysis objectives, assumptions, load cases, acceptance criteria, and verification strategies.
• Develop analytical, finite element, reduced-order, and system-level models to predict performance and optimize complex mechanical and Multiphysics systems.
• Perform advanced linear and nonlinear structural, thermal, dynamic, vibration, fluid, or coupled-physics analyses.
• Select and defend modeling assumptions, material properties, interfaces, boundary conditions, mesh strategies, solver settings, and convergence criteria.
• Verify and validate results through first-principles calculations, benchmarks, sensitivity and uncertainty assessments, independent checks, and test correlation.
• Guide concept selection, detailed design, integration, and qualification by identifying performance drivers, technical risks, margins, and practical improvements.
• Resolve test, manufacturing, and field issues through physics-based root-cause analysis and computational modeling.
• Define the analysis, testing, measurements, and risk-retirement activities required to establish confidence in proposed designs.
• Communicate methods, results, uncertainties, risks, and recommendations clearly to technical and nontechnical stakeholders.
• Build trusted cross-functional relationships, actively consider alternative perspectives, and influence decisions through expertise, listening, and constructive collaboration.
• Provide technical direction, peer review, and mentoring to engineers, suppliers, consultants, and external partners.
• Improve organizational capability through reusable methods, modeling standards, automation tools, and computational workflows.
• Plan and deliver analysis activities while managing quality, schedules, dependencies, documentation, configuration traceability, and applicable EHS requirements.

Education & Experience

• Master’s degree or PhD in Mechanical Engineering, Aerospace Engineering, Applied Mechanics, Computational Engineering, Engineering Science, or a closely related discipline is strongly preferred. A bachelor’s degree with substantial directly relevant analysis experience may be considered.
• Minimum of five years of progressive experience in engineering analysis, computational mechanics, complex mechanical-system development, physical sciences, or a related technical field.
• Demonstrated expertise in finite element methods, solid mechanics, numerical methods, computational modeling, and physics-based problem solving.
• Advanced experience in linear or nonlinear structural analysis, including contact, material or geometric nonlinearities, joints, stability, fatigue, or fracture.
• Expertise in one or more additional areas, such as structural dynamics, vibration, transient response, heat transfer, thermal distortion, computational fluid dynamics, or Multiphysics simulation.
• Experience verifying and correlating analytical models with experimental or qualification-test data.
• Experience with high-precision equipment, semiconductor equipment, opto-mechanical systems, mechatronics, aerospace systems, scientific instruments, or similarly complex products is preferred.
• Experience with optimization, sensitivity analysis, uncertainty quantification, probabilistic methods, or reduced-order modeling is beneficial.
• Experience with ANSYS, Siemens NX/Simcenter, Abaqus, Nastran, or equivalent tools, together with Python, MATLAB, Mathematica, or similar technical computing environments, is preferred.
• Demonstrated collaborative leadership through technical direction, peer review, mentoring, or coordination across multidisciplinary teams.

Skills

Technical & functional skills

• World-class command of engineering mechanics, finite element methods, numerical methods, and physics-based modeling within one or more relevant technical disciplines.
• Ability to identify dominant physical mechanisms and convert complex behavior into models appropriate to the engineering decision, technical risk, available data, and schedule.
• Ability to establish, verify, validate, and clearly defend modeling assumptions, methods, uncertainties, limitations, and conclusions.
• Strong mechanical intuition regarding load paths, interfaces, sensitivities, performance drivers, and failure modes.
• Ability to solve multidisciplinary problems involving mechanical, thermal, fluid, electromagnetic, optical, or controls interactions.
• Ability to evaluate tradeoffs and recommend practical solutions considering performance, manufacturability, serviceability, cost, safety, compliance, and schedule.
• Ability to recognize technical gaps and define the additional analysis, testing, or research required to resolve them.
• Ability to communicate complex technical information clearly and credibly to audiences with different levels of expertise.
• Ability to lead through technical competence, relationships, and influence rather than relying solely on formal authority.
• Strong customer focus, attention to detail, technical integrity, and commitment to quality and timely delivery.
• Ability to work autonomously and collaboratively in a demanding environment with changing priorities.

Behavioral & leadership skills

• Drives Results: Establishes clear priorities, takes ownership, manages tradeoffs, and delivers technically sound results with the required quality and timing.
• Demonstrates Self-Awareness: Understands personal strengths, limitations, and impact on others; seeks feedback; and adapts behavior to improve collaboration and results.
• Values Differences: Seeks, respects, and integrates different perspectives, disciplines, cultures, and working styles.
• Builds trusted relationships through humility, credibility, active listening, clear communication, and respect for others’ expertise.
• Demonstrates intellectual curiosity, constructively challenges assumptions, and remains open to alternative methods and conclusions.
• Communicates uncertainty, limitations, risks, and unfavorable findings objectively and with technical integrity.
• Works effectively across organizational and disciplinary boundaries to resolve complex problems.
• Develops other engineers, strengthens the broader technical organization, and demonstrates the potential to become a senior technical leader or analysis architect.
