Marketing Working Student (m/f/d)

Spectroplast is the silicone manufacturing partner from first prototype to full production. We 3D print production-grade parts in true silicone (not TPU, TPE, or flexible resin), on demand, with no tooling and no minimum order. Engineering teams in medical devices, robotics and precision manufacturing choose how they work with us: order parts online, co-develop an application with our engineers, or print in-house with our silicone materials. An ETH Zurich spin-off based in Munich, with 700+ customers and 120,000+ parts shipped.

Help us keep our content, social and paid channels running and make them better.

In a time when more and more is digital and generated by AI, we offer something you can hold in your hand: parts made from true silicone. Customers regularly give us excellent feedback on their quality. Now we want to take the next big step, and we need a reliable team behind our channels.

Our marketing team is small, and our channels need someone who looks after them day to day. You keep our content, social posts, newsletter and Google Ads running, improve what can work better and bring your fresh ideas.

You report to our Head of Business Development & Marketing, who sets the priorities and guides you. You get your own tasks from the start, and we want to hear your ideas.

AI is part of how we work every day. Agents and AI tools help with research, drafts and analysis. You use them too and check the results: people decide what goes out.
