Graduate (Year-Round) Internship - Digital Twin Development for Biorefinery Processes

Graduate (Year-Round) Internship – Digital Twin Development for Biorefinery Processes Location: Golden, Colorado Position Type: Intern (Fixed Term) Hours per Week: 40 (full‑time) Job Overview The Integrated Carbon Conversion Processes (ICCP) Group within NREL's Catalytic Carbon Transformation and Scale‑Up (CCTS) Center has an opening for a Graduate Internship position. The selected candidate will support senior process engineers, modelers, and data scientists in developing a digital twin for an experimental biological and thermocatalytic conversion platform. The goal of the project is to create a virtual representation of key unit operations, enabling real‑time monitoring, dynamic simulation, and predictive analytics for biomass and waste conversion to produce biofuels and bioproducts. Responsibilities Design and implement process models representing biomass conversion, upgrading, and separation units. Integrate sensor data and historical process data into the digital twin architecture. Develop simulation tools and dashboards for visualization, control, and scenario analysis. Contribute to model validation using pilot‑scale data and collaborate on experimental feedback loops. Document assumptions, system architecture, and modeling workflows for reproducibility and team collaboration. Participate in team meetings and present regular progress updates. Contribute toward peer‑reviewed manuscripts and other technical documentation. Basic Qualifications Minimum 3.0 cumulative GPA. Enrolled as a full‑time student in a bachelor’s, master’s, PhD, or recent graduate program, with eligibility to work for up to one year. Additional Required Qualifications Currently pursuing or recently completed a master’s or PhD in computational sciences, computational engineering, mechanical engineering, chemical engineering, biological engineering, chemistry, biology, or a related field. Experience programming in Python and/or C++. Experience modeling chemical reactors (e.g., using Cantera) and integrating with computational fluid dynamics (CFD) frameworks. Preferred Qualifications Experience building techno‑economic models using software platforms (e.g., Aspen Plus). Exposure to artificial intelligence/machine learning methods for process optimization or anomaly detection. Experience with digital twin platforms (e.g., AnyLogic, TwinCAT, Siemens Xcelerator). Interest in bioprocessing, energy systems, or sustainable technology development. Strong problem‑solving, communication, and collaboration skills. Salary Range $44,500 – $71,200 for a 40‑hour per week, full‑time position. Benefits Summary Benefits include medical, dental, and vision insurance; a 403(b) Employee Savings Plan with employer match; and sick leave where required by law. Some positions may be eligible for relocation expense reimbursement. Equal Opportunity Employer All qualified applicants will receive consideration for employment without regard to age, color, disability, gender identity, genetic information, marital status, domestic partner status, military or veteran status, national origin/ancestry, race, religion, creed, sex (including pregnancy, childbirth, breastfeeding), sexual orientation, and any other applicable status protected by federal, state, or local laws. #J-18808-Ljbffr National Renewable Energy Laboratory
