The site will provide a **state-of-the-art cleanroom environment for assembly & testing of our high-end systems** and will contribute to engineering for the **next generation of products**. Operations are planned to start in 2027 with a rapid ramp-up. Beyond technology, the new location is designed as a **modern workplace** with state-of-the art office and amenities —built to foster collaboration and a strong focus on people's wellbeing. **Who we are looking for** We are looking for **purpose-driven builders**: hands-on professionals with entrepreneurial spirit who enjoy setting up structures, improving processes and taking ownership in a fast-moving environment. As pioneers of our Malaysia site, you will help to shape not only your function, but also how we work together locally — while being connected to a global team of around **1,000 employees from ~60 nationalities** across Asia, Europe and the US. We offer competitive benefits, outstanding technical expertise, development opportunities and training. **About the role** We are looking for Engineers of varying experience to join our team in Malaysia. As part of our Engineering team, you will develop and design mechanical systems and functions for next-generation semiconductor systems. You will lead the development of complex mechanical architectures that significantly shape the performance and reliability of our systems. You will take ownership of cross-functional challenges, drive critical system-level decisions and trade-offs, and shape the technical direction across disciplines. You will ensure compliance, enhance performance, and embed robustness throughout the entire lifecycle — from concept through production. With strong systems thinking and sound engineering judgment, you will identify risks across interfaces at an early stage, confidently navigate uncertainty, and guide high-impact technical decisions that move our technology forward. **** **Responsibilities** - Develop and Design of mechanical system architectures, define interfaces and manage clear, testable requirements - Leads FEM interpretation for complex structures across multiple regions, performs sensitivity and correlation studies, resolves critical design issues, and adapts load case definitions to region-specific parameters (e.g. Seismic). Apply regional safety factors and ensure compliance with international engineering and safety standards - Develop robust tolerance concepts and geometric dimensioning strategies for large-scale assemblies - Conduct structured problem solving and risk assessments to prevent integration and field failures - Drive design for manufacturing, cost optimization and distortion control initiatives - Manage technical documentation, configuration changes, engineering changes and lifecycle impacts - Provide technical leadership, mentor engineers and align cross-functional stakeholders - Technical management of new manufacturing suppliers from prototyping to series production. - Integrate exhaust, vacuum, heating and temperature control components according to requirements into already developed products and projects - Create and review-ready technical drawings, specifications and change project and product documentation **Qualifications & Skills** - Degree in Mechanical Engineering or related discipline with 2–10 years of relevant experience - Strong expertise in mechanical design of structures for complex equipment (e.g. vacuum technology, frame, cladding, cooling automation, etc.) - Experience in finite element simulation and interpretation - Strong experience with common manufacturing methods in equipment design - Solid knowledge of geometric dimensioning and tolerance stack-up in multi-interface systems and GD&T - Experience in requirements engineering, risk assessment and structured change management - Advanced proficiency in 3D computer-aided design and product lifecycle management systems - Advantage to be proficient in CREO/Pro-E and ERP systems such as SAP - Strong analytical mindset - Proven ability to lead technical decisions, manage risks and align cross-functional teams - Fluent English communication skills (written and spoken) **Working Conditions** - Role based at AIXTRON Malaysia Sdn.
