Our environment is a vibrant research and development hub where professionals from diverse disciplines collaborate to tackle complex challenges and create solutions to relevant problems—especially in health, energy, renewable materials, and sustainability. We are a Social Organization supervised by the Ministry of Science, Technology and Innovation (MCTI), at the forefront of scientific research in Brazil. We operate Sirius—the largest scientific infrastructure ever built in the country—and are currently developing the Orion project: a dedicated laboratory complex for advanced pathogen research, which will be available to the national and international scientific communities. We offer a wide range of career opportunities for professionals with diverse backgrounds. At CNPEM, we conduct cutting-edge research spanning nanotechnology, biosciences, biotechnology, bio-renewables, scientific instrumentation, and accelerator physics—carried out respectively by the National Nanotechnology Laboratory (LNNano), Biosciences Laboratory (LNBio), Bio-renewables Laboratory (LNBR), and Synchrotron Light Laboratory (LNLS). These initiatives are strengthened by challenging technology projects and frontier-engineering solutions led by the Adjunct Directorate of Technology (DAT). This entire ecosystem is supported by an integrated network of strategic areas—including information technology, communications, project management, legal & compliance advisory, human resources, finance, procurement, sustainability, and innovation—distributed across the General Directorate (DG) and the Shared Services Directorate (DSC). The Adjunct Infrastructure Directorate (DAI) ensures facility maintenance, engineering support, and architectural development, providing optimal conditions for all activities. Ilum School of Science complements these efforts with a Bachelor’s program in Science and Technology, delivering innovative training to prepare future generations of scientists for tomorrow’s challenges. We believe success is achieved through dedication, collaboration, and clear purpose. We value continuous development of our professionals and students, offering an inspiring and supportive environment for professional and personal growth. We are committed to sustainability and seek solutions that promote a greener future. We prioritize the care and well-being of our staff while valuing diversity and fostering an inclusive environment where everyone is welcome and respected. **If you are passionate about science and seeking a place where you can make a difference, join us at CNPEM.**
