Why work with us?
At ABN Cleanroom Technology, we combine the best of three worlds:
Family Business
A warm, engaged atmosphere focused on long-term growth and autonomy.
Financially Sound
Stability and room for growth, innovation, and ambition.
Growth Company
Opportunities to develop yourself in a dynamic, international context.
Through our Helium Talent Management platform, we support continuous learning and talent development. This is how we ensure our employees’ well-being, share strong values, and create impact together.
The HELIUM Talent Management Platform
Wondering why Helium? At ABN Cleanroom Technology, we love innovation and digitalization. Helium is therefore a small nod to the cryptocurrency of the same name. Additionally, helium is known as laughing gas – a reference to the fun we have in the workplace. But above all, the abbreviation stands for the noble gas (He). Within ABN Cleanroom Technology, we see He as Human Empowering. Because empowering people is what we strive for with this platform.
Below you’ll discover the exact meaning of each letter in our HELIUM acronym.
Humble
Humility doesn’t mean minimizing our achievements. It means maintaining a balanced and realistic view of ourselves while showing genuine appreciation for others.
Entrepreneurial
We encourage behavior that contributes to innovation and growth. Embrace an innovative mindset, stay curious and committed, and take initiative to identify problems, inefficiencies, or areas for improvement.
Loyal
We value building strong relationships, maintaining open communication, and fostering a culture of appreciation. This contributes to a mutually loyal and valuable relationship within our company.
Innovative
We believe that by encouraging a mindset of continuous improvement and creative thinking, we bring fresh ideas and solutions to the organization. Stay curious, be open to change, and dare to challenge the status quo.
United
We experience that connection creates a sense of belonging, strengthens morale, and contributes to overall success. That’s why we embrace diversity and inclusion, participate in team-building activities, and encourage training and knowledge sharing.
Mastering
Mastery is an ongoing journey, not a final destination. It encompasses continuous development, sharpening skills, and a commitment to excellence. Stay up-to-date with industry trends, innovations, and best practices.
