AIXTRON's new manufacturing & engineering hub in Malaysia
We are building a new greenfield manufacturing and engineering hub in Batu Kawan, Penang. 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
As a Senior Mechanical Engineer specialising in Vacuum Design, you shape the heart of our deposition platforms. You will architect and optimize highly complex vacuum and exhaust systems that enable cutting-edge technology to perform at its limits.
With deep technical expertise and a strong system-level mindset, you will turn challenging requirements into robust, high-performance solutions. You will ensure not only peak performance, but also compliance, manufacturability, and long-term lifecycle stability — balancing innovation with reliability.
In this role, you don't just design components — you define system architectures, solve critical cross-functional challenges, and drive engineering excellence from concept to implementation.
Responsibilities
- Design and optimize complex vacuum architectures including pumps, sealing concepts, pressure control and contamination mitigation
- Lead exhaust and gas handling system design for demanding chemistries and tight packaging conditions
- Perform vacuum calculations and simulations (pump-down, conductance, pressure distribution, outgassing) and validate models against measurement data
- Develop mechanical system architectures, define interfaces and manage clear, testable requirements
- Apply structured problem solving, root cause analysis and risk assessment to resolve cross-functional issues
- Drive design for manufacturing, cost optimization and tolerance strategies including geometric dimensioning
- Ensure compliance with international standards and proactively steer documentation quality and configuration changes
- Provide technical leadership, mentor engineers and align stakeholders across disciplines and regions
- Technical management of new manufacturing suppliers from prototyping to series production.
Qualifications & Skills
- Degree in Mechanical Engineering or related discipline with 5–10 years of relevant experience
- Strong expertise in vacuum system design, simulation and engineering calculations
- Solid understanding of pressure, flow and thermal systems, with hands-on troubleshooting capability
- Solid knowledge of geometric dimensioning and tolerance stack-up in multi-interface systems and GD&T
- Experience in system architecture definition, requirements engineering, failure mode and effects analysis, and change management processes
- 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
- High learning agility and ability to adapt to new technologies and complex environments
- Fluent English
Working Conditions
- Role based at AIXTRON Malaysia Sdn. Bhd.
- Majority of work at the Batu Kawan site.
- Occasional travel to Headquarters in Germany or other regional sites.
