M&P at CFS is organized around three primary thrusts: engineering, test and characterization, and development programs. The work is undertaken in support of delivering SPARC, the net energy tokamak under construction in Devens, MA, and ultimately in designing the ARC fusion power plant. These devices pose unique materials challenges including neutron fluxes produced by deuterium-tritium fusion, high heat loads, molten salt coolant systems, complex component topologies, high magnetic fields, and high mechanical loading in cryogenic conditions.\nTo support this mission, the CFS Materials Department is seeking a Computational Materials Scientist with expertise in process-structure-properties relationships, physics informed modeling, and materials in extreme environments. The ideal candidate would have a background in both computational materials simulation methods, and materials science and/or physical chemistry. The responsibilities will include physics-based modeling, synthetic data generation, and first-principles modeling and simulation to support development of CFS materials. They will collaborate with other engineers and subject matter experts to identify highest sensitivity parameters and prioritize experimental work for greatest impact to decreasing uncertainty\nWhat you'll do:\nUse and build computational toolsets, workflows, and methods to generate predicted material properties in extreme environments including temperature, radiation, and magnetic field with uncertainty bounds informed by physical mechanisms\nIdentify chemical and microstructural features that strongly impact material performance in extreme environments, and quantify the relationships for use in optimization for engineering application\nInform design of experiments for materials in extreme environments, including simultaneous corrosion, stress, and irradiation. As well as magnetic field, electric field, and high temperature.\nIn collaboration with design and analysis engineers, develop material design curves methodology capable of determining statistically significant minimum properties for tokamak applications such as low and high cycle fatigue, dielectric breakdown, radiation effects.\nIdentify gaps in knowledge and experimental capability which can be filled via simulation or model building\nAssist in benchmarking and creating metrics for material property variability and sources of variability in manufacturing, fabrication, assembly, and processes\nCollaborate with other M&P Engineers to create workflows to enable the appropriate capture, storage, data visualization and analysis of data generated within the materials domain.\nSupport writing materials standard specifications\nStay current with the evolving technology and modeling techniques\nWhat we’re looking for:\nMaterials Science and Engineering, Applied Physics, Applied Mathematics, Physical Chemistry, Computer Science or related field\nMinimum of 7+ years experience in experimental or computational materials science\nExperience using computational materials science tools and integrated computational materials engineering (ICME) tools to answer specific scientific or engineering questions across length scales\nImplementation and/or authorship of codes for calculation and analyses of material properties and microstructures\nPredictive models for material properties and microstructure evolution in extreme environments\nValidation of models with experimental data or physical mechanism bounds\nUnderstanding process-structure-properties-performance principles and fundamental mechanisms responsible for property changes in extreme environments\nUnderstanding of the underlying models that enable materials simulation methods across length scales including; Atomistic, molecular dynamics, density functional theory, Monte Carlo, phase field, crystal plasticity, dislocation dynamics, and computational thermodynamics, finite element\nScientific computing, numerical algorithms, FEM, FD, FVM, BEM, eigen/linear/PDE solvers, convex optimization, computational geometry, advanced statistical methods\nHigh-performance computing: distributed processing, message parsing interface, gpu acceleration\nUnderstanding of the sensitivity to uncertainty in the inputs and outputs of those calculations or models\nDemonstrated ability to work effectively cross-functionally\nExcellent organizational skills including prioritization of multiple concurrent projects\nAbility to break down complex problems into smaller deliverables that add value\nBonus points for:\nExperience displaying complex quantitative data in a simple, intuitive format and presenting findings clearly and concisely\nExperience making and justifying decisions in fast paced engineering settings\nWritten and verbal communication with technical teams\nTaking under-defined problems and driving them to a state of completion\nOperating in a flexible, service-oriented engineering domain team\nMust-have Requirements:\nPerform activities such as typing and sitting for extended periods of time\nDedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics\nWillingness to travel or work required nights/weekends/on-call occasionally.
