Silex Microsystems is the world’s leading pure-play MEMS foundry, partnering with global clients to develop some of the most advanced MEMS products in the world. As a Product Manager in our Product Development team, you will play a key role in pushing the boundaries of what is technically possible — working hands-on with cutting-edge processes while driving complex development projects forward. This is a highly technical, project-driven role where you combine microfabrication expertise with strong project management to take products from concept to market. Read more about Silex here. The Team You will join our Product Development team of around 40 colleagues, including Product Managers, Process Design Engineers and CAD Engineers, and you’ll be reporting to a Group Manager. The team works at the core of Silex’s offering — translating customer designs into manufacturable MEMS products. Collaboration is key, and you will work closely with both internal experts and international customers in a highly knowledge-driven environment. The role In this role, you will lead the development of MEMS products from early concept through prototype, combining technical depth with structured project management. Customers typically come to Silex with a design concept, and together with our CAD Engineers and technical experts, you will evaluate and shape that design to ensure it is manufacturable. Early in the process, you will bring together specialists from different process areas to define a robust concept and create a scalable process flow, and a recipe for the new product. In this concept phase, you will be ensuring that all critical aspects are considered before the customer approves the concept, and the project moves into prototyping. As the project progresses into the prototype phase, you will own the overall execution — ensuring timelines are met, risks are managed, and technical challenges are solved along the way. A part of the role is hands-on work in the cleanroom. After each process step, you will evaluate the outcome using tools such as SEM analysis to determine whether the desired result has been achieved. Based on your findings, you will work closely with Process Engineers to tweak parameters in processes to achieve the desired result. Finally, you’re responsible for the delivery of the final prototype to the client. To ensure a strong start, you’ll receive hands-on training from an experienced colleague to familiarize you with our development process and tools before being in client discussions. After a while, you will start acting as the technical interface towards customers, leading discussions around progress, challenges, and next steps. In this role, you will Drive MEMS development projects from concept to the delivery of a final prototype. Evaluate customer designs and ensure manufacturability together with CAD and process experts. Define process flows and build fabrication recipes for new products. Bring together cross-functional experts early in the project to ensure a robust concept. Analyze process results using SEM and other characterization methods. Collaborate with Process Engineers to achieve desired results after each fabrication step. Own project timelines, order portfolios, progress, and delivery. Identify risks, troubleshoot issues, and ensure forward momentum. Act as the technical lead towards customers. Lead technical discussions, reporting, and planning. What We’re Looking For A Master’s degree or PhD with coursework in microfabrication/ nanotechnology. Experience with microfabrication through work or academic research, ideally using processes like lithography, plasma deposition and plasma etching. Strong communication skills and the ability to discuss technical topics in English. Swedish is considered highly beneficial as a lot of internal documentation is written in Swedish. Previous experience with customer interaction. Several years of industry experience in production environments, leading technical projects. To succeed in the role, we also think that you are A clear and adaptable communicator, able to engage both colleagues and customers. Organized and methodical in how you drive projects forward. Curious and eager to deepen your expertise in MEMS. Business-minded and focused on delivering value to customers. About the recruitment process We review applications on a rolling basis, so we encourage you to apply as soon as possible. To apply, please attach your CV or LinkedIn-profile, and answer a few questions. If you progress through the full process, you will start with a digital interview with one of our Talent Acquisition Partners, followed by a personality and logical ability test. Next, you will meet with one of our Group Managers together with a Talent Acquisition Partner for an in-person interview, and finally with our VP of Product Development for a concluding interview. Before an offer, we also conduct reference checks, a background check, and a drug test. Randomized alcohol- and drug testing is conducted for all of our employees during the employment.
