Maintenance Engineer - Plasma
As part of building our new Maintenance Engineering organization, we are expanding our team with several Maintenance Engineers—this role focused on our Plasma Area. This is a key position where you will take ownership of critical equipment performance, drive strategic improvements, and play a central role in maximizing uptime in one of the most advanced areas of our production.
The team and the area
You will be part of a Maintenance Engineering team of seven engineers, led by our Maintenance Manager.
The Plasma area is a critical part of our production, where thin films are deposited on or etched from silicon wafers. The equipment landscape includes PVD, PECVD, ALD, plasma etch systems, and evaporators—all operating in high-vacuum environments, with most processes relying on high-energy plasma to achieve precise material transformations. Working closely with the Plasma team, you will collaborate with ten engineers and ten technicians. Together, you take ownership of the plasma equipment and processes—continuously monitoring performance, troubleshooting complex issues, and driving improvements.
About the role
As a Maintenance Engineer, your main responsibility will be to improve equipment uptime within the Plasma area. A key part of this is developing how we collect and use equipment data, as well as defining relevant KPIs and SPC methods related to uptime.
You will also standardize work routines and support service technicians in adopting a consistent and structured way of working. As we continue to expand, new equipment is constantly being purchased and installed—you will play an active role in supplier discussions as well as in collaboration with the Area Manager and Process Engineers.
In this role, you will:
Perform maintenance activities, including documentation and continuous improvement of maintenance routines.
Define and implement KPIs and SPCs for equipment performance.
Coordinate with equipment vendors to plan service interventions.
Drive improvements in equipment uptime.
Lead root cause analysis together with the service team and document findings.
Support the facility team with installations, modifications, and upgrades of existing tools.
Ensure safety in all maintenance-related activities within the area.
Drive improvement projects locally and contribute to cross-functional initiatives.
We are looking for someone who has:
A Master’s degree in engineering, specializing in Mechanical, Electrical, Applied Physics, Materials Science, or a related field.
At least three years of industry experience, including a minimum of one year working with plasma tools.
Strong problem-solving skills and a data-driven mindset.
A willingness and ability to learn and develop new skills.
The ability to take ownership and drive projects to completion in a structured way.
Strong communication skills and the ability to collaborate effectively with relevant stakeholders.
At least a basic understanding of written Swedish, along with a willingness to further develop this skill if not already fluent.
