**Overview** PNNL's Earth System Science Division enables energy independence and national security through leadership in earth systems science, engineering, and decision analytics. Our work focuses on solving complex problems in the dynamic Earth system. Our interdisciplinary scientists steward a breadth of efforts that encompass research on plants to groundwater science and coastal zones, to storm prediction. Our research focuses on understanding and mitigating operational risks at the interface of human and natural environments. This includes predicting the impacts of natural hazards and extreme climate events on Earth and human systems, along with the impacts of wildfire, flooding, sea level rise and storm surges. We focus on understanding and mitigating environmental contamination and increasing the resiliency, security and sustainability of water resources. We provide geointelligence through advanced sensing and data analytics to forecast complex system behaviors and operational performance to understand human-natural systems. This includes informed decision making and enhanced community resilience, advanced monitoring, and remote sensing of environmental systems for energy and national security. It also includes developing energy systems, including geothermal energy, sustainable oil and gas production, storage and utilization, along with carbon sequestration. Driven by a “science-to-solutions” philosophy, we provide scientific leadership and technology to enhance national security, mitigate natural hazards and optimize disaster response. In the critical areas of energy, environment, intelligence, and defense, we deliver insights and decision support through the development of tools and solutions. **Responsibilities** The Energy and Critical Materials team at the Pacific Northwest National Laboratory (PNNL) is seeking a Materials Scientist 2 to support research and development of advanced cement, composites, and alloys for building and transportation infrastructure as well as subsurface applications. We are specifically interested in a highly motivated, capable individual with significant training in novel materials engineering, performance evaluation, and their physical and chemical characterization under ambient and extreme conditions such as those encountered in geothermal applications. The primary job responsibility will be to design, prepare, and evaluate cement, concrete, and casing materials including the development of supplementary cementitious materials, carbon-storing cementitious materials and composites, self-healing concrete, and corrosion-resistant alloys towards optimizing their chemical and thermal stability, structural integrity, and mechanical performance in complex environments. The research is aimed at developing environmentally friendly, smart materials for enhanced geothermal systems, carbon storage, as well as for concrete-based construction. Project work will include both computational and experimental aspects, including working with high temperature/pressure reactors and will be performed by a team of collaborators. Analytical techniques used include x-ray micro-tomography, thermogravimetric analysis, calorimetry, high-resolution optical and scanning electron microscopy, high-pressure & high-temperature viscosity analysis and material mechanical strength analysis. Spans fundamental materials science to applied materials engineering. Synthesizes and studies the structures and physical/chemical properties of various natural, synthetic, and composite materials including metals, alloys, ceramics, semiconductors, polymers, rubber, glass, and combinations of these materials. Studies the structures of materials from atomic to large length scales and performs short- and long-term characterization, modeling, or testing of these materials to understand their behavior and determine ways to improve them or develop new materials with specific properties. Develops individual steps and combined processes for manufacturing, joining, finishing, treating, and strengthening materials. Develops computational models of materials that describe structures, properties, and performance of materials. Specific research areas include physics, chemistry, materials science, materials engineering, glass science, ceramic science, metallurgy, manufacturing and process engineering, corrosion science, and polymer science. **Qualifications** Minimum Qualifications: + BS/BA and 2 years of relevant experience -OR- + MS/MA -OR- + PhD Preferred Qualifications: + Candidate must have a PhD in Mechanical Engineering, Materials Science or closely related field within the past ten years from an accredited college or university. + Candidates must have in-depth knowledge and practical experience in complex materials mechanics, cementitious materials, polymer-cement, and biopolymer-cement materials with emphasis in low-carbon, self-healing, and/or nanoreinforcing cement and concrete materials, alloys, and their interaction with formation rock, fluids, under different physicochemical environments. A background in materials chemistry, particularly as it relates to changes in physical and chemical properties is desirable. Experience with high pressure/temperature systems would be highly beneficial. + The candidate will be expected to utilize and/or interpret characterization techniques such as X-ray microtomography, permeability analysis, rheology analysis, compressive, tensile, and flexural strength. + Candidate must be a team player with excellent written and oral communication skills + Candidate must display an outstanding ability to effectively plan, perform, and communicate scientific research, with demonstrated ability to conduct original scientific research and publish results in peer-reviewed journals as well as writing proposals towards funding opportunities in the above-described areas. **Hazardous Working Conditions/Environment** Lab Work **Additional Information** Not Applicable. **Testing Designated Position** Not a Testing Designated Position. **About PNNL** Pacific Northwest National Laboratory (PNNL) is a world-class research institution powered by a highly educated, diverse workforce committed to the values of Integrity, Creativity, Collaboration, Impact, and Courage.
