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 engineer 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 Reactor design, you are at the heart of our reactor innovation. You will lead the development of complex mechanical architectures that define the performance and reliability of our systems.

Taking ownership of cross-functional challenges, you will drive critical system-level trade-offs and shape technical direction across disciplines. You ensure compliance, elevate performance, and embed lifecycle robustness from concept through production.

With strong systems thinking and a sharp engineering mindset, you anticipate risks across interfaces, navigate uncertainty with confidence, and guide high-impact technical decisions that move our technology forward.
