To work in the Simulation and Artificial Intelligence Group of the National Laboratory for Nanotechnology (LNNANO) We operate at the fascinating intersection of nanoscience, computational materials science, condensed matter physics, and artificial intelligence, where we seek to unravel the complex behaviors and properties of materials at atomic and molecular levels. Leveraging high-performance computing infrastructure, we apply state-of-the-art computational techniques—including density functional theory, molecular dynamics, and machine learning—to investigate and design new materials with specific properties. Our focus lies on understanding the fundamental physics governing material behavior at the nanoscale and harnessing this knowledge to develop materials for next-generation applications in electronics, quantum technologies, energy storage, sustainability, and beyond. Through close collaborations with experimental groups and industrial partners, we are particularly interested in exploring machine learning and deep learning algorithms to accelerate the discovery of new materials, predict their properties, and optimize their performance—significantly reducing development costs. By bridging the gap between theoretical predictions and practical applications, we aim to expand the frontiers of materials science and contribute to the development of transformative technologies and innovative solutions for global challenges in energy, environment, and health. **Responsibilities and Duties** * Provide technical support to users of HPC environments and scientific computing systems; * Assist researchers and users of laboratory facilities; * Perform preliminary diagnosis and resolution of issues related to jobs, environments, and access; * Open detailed service tickets and provide technical follow-up on solutions; * Administer Linux systems in scientific computing environments; * Manage and support scientific software and computational environments; * Support scientific storage infrastructure; * Interact with users to guide best practices; * Produce technical documentation and support process standardization; * Support implementation and improvement of services and projects; * Interface with internal IT teams and third-party service providers. **Requirements and Qualifications** **Requirements** * Completed undergraduate degree in: Computer Science, Computer Engineering, Information Systems, or related fields; * Candidates from scientific disciplines (e.g., Physics, Engineering) with strong, proven computational experience will also be considered; * Experience with Linux systems (intermediate to advanced user level); * File manipulation, permissions management, process handling, and terminal usage; * Basic knowledge of Linux system administration; * Fundamental user, service, and environment configuration management; * Experience with shell scripting (bash) for task automation; * Familiarity with scientific computing or compute-intensive environments; * Execution of scripts, pipelines, or technical workloads; * Basic knowledge of networks and distributed systems; * Ability to diagnose technical issues (logs, errors, basic performance analysis). **Desirable:** * Prior experience with HPC (High Performance Computing); * Experience using or administering clusters; * Familiarity with job schedulers (e.g., Slurm); * Experience with high-performance storage (NFS, BeeGFS, Lustre, or similar); * Knowledge of containers (Singularity/Apptainer, Docker); * Experience installing and maintaining scientific software; * Basic knowledge of Python or another language for automation/analysis; * Experience in scientific research environments (universities, laboratories, research centers); * Familiarity with GPU computing (CUDA, NVIDIA drivers); * Knowledge of performance monitoring and troubleshooting tools. **Additional Information** **Our Benefits** Health Insurance – Unimed Dental Insurance – Uniodonto Psychological Support – Telavita Life Insurance – Allianz Private Pension Plan – BrasilPrev Maternity Leave (extended to 6 months) Paternity Leave (25 days) Childcare Allowance On-site Restaurant Meal and/or Food Allowance – Pluxee (R$1\.020,00/mouth) Shuttle Service Transportation Voucher On-site Parking Club – Telecamp Club – Free SESC Association Membership Wellhub – Gym Discounts Partnerships with companies offering discounts **We reaffirm our commitment to diversity, equity, and inclusion, encouraging applications from people with disabilities, neurodiverse individuals, women, LGBTI\+, people of diverse ethnicities, generations, and body types, as well as other socially marginalized groups.** At the Brazilian Center for Research in Energy and Materials (CNPEM), we are driven by a passion for science. Our environment is a vibrant hub for research and development, where professionals from diverse specialties collaborate to tackle complex challenges and create solutions for pressing issues—particularly 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 community. We offer a wide range of career opportunities for professionals with diverse profiles. At CNPEM, we conduct cutting-edge research spanning nanotechnology, biosciences, biotechnology, biofuels, scientific instrumentation, and accelerator physics—carried out respectively by the National Laboratories of Nanotechnology (LNNano), Biosciences (LNBio), Biofuels (LNBR), and Synchrotron Light (LNLS). These initiatives are reinforced by challenging technology projects and frontier engineering solutions led by the Deputy Directorate for 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 Deputy Directorate for Infrastructure (DAI) ensures facility maintenance, engineering support, and architectural development, creating optimal conditions for advancing all activities. Ilum School of Science complements these efforts with a Bachelor’s program in Science and Technology, offering an innovative curriculum that prepares future generations of scientists for tomorrow’s challenges. We believe success is achieved through dedication, collaboration, and a clear sense of purpose. We value continuous development for our professionals and students, providing an inspiring and supportive environment for both professional and personal growth. We are committed to sustainability and actively seek solutions that foster a greener future. We prioritize the care and well-being of our staff while valuing diversity and promoting an inclusive environment where everyone is welcome and respected. **If you are passionate about science and seek a place where you can make a difference, join us at CNPEM.**
