Materials Scientist

Position Overview Solid Power is seeking a Multiphysics Modeling Scientist to join our talented team working to revolutionize the battery industry through the development of next‑generation, all‑solid‑state rechargeable batteries. The preferred candidate will have significant experience working with and using multiphysics simulations to model chemical systems, heat transfer dynamics, and electrochemical device behavior. The candidate will be expected to guide synthetic approaches for dry, inorganic powders by modeling conditions in high‑throughput powder reactors. They will also work to update existing thermal abuse models that integrate atom‑scale reaction kinetics with continuum‑scale heat transfer dynamics. The candidate should be comfortable building P2D/P4D DFN models and using the approaches to guide experimental planning, especially as it relates to battery formulation improvements. Job Duties Develop continuum‑scale reactor models for dry inorganic powder synthesis, coupling heat transfer, gas flow, mass transport, and reaction kinetics to guide reactor conditions and experimental planning. Upgrade existing COMSOL‑based implementations for thermal abuse modeling of ASSB cells. Develop and validate mathematical models (both fundamental physics‑based and data‑driven) to predict thermal, mechanical, and electrochemical behavior of ASSB materials, sub‑assemblies, and finished cells. Work with subject matter experts to develop experimental plans to isolate and quantify key model parameters, while producing minimal solvers that can be used by scientists/engineers. Collaborate with subject‑matter experts to refine and continually validate modeling approaches, while employing best‑practice workflows (e.g., mesh sensitivity analysis, ablation testing, unit testing, parameter sensitivity quantification). Clearly explain to internal stakeholders the uncertainty in modeling predictions and write documentation on proposed upgrades that could be used to improve certainty. Collaborate with data scientists on strategies to accelerate multiphysics modeling solvers and guide virtual experiment prioritization (e.g., Bayesian approaches). Collaborate with atomic‑scale and coarse‑grained modeling teammates to translate their outputs into continuum‑scale model inputs, assumptions, parameters, and validation targets. Qualifications & Requirements Master’s or Ph.D. in Computational Chemistry, Materials Engineering, Chemical Engineering, or a related electrochemical discipline. 2+ years of professional experience using commercial software to develop multiphysics models of lithium‑ion batteries. Deep understanding of electrochemistry, preferably with at least some experience in battery systems. Proficiency with Python and common data science libraries such as Pandas, NumPy, and SciPy. Strong analytical and statistical problem‑solving skills, with specific experience configuring solvers for regression and parameterization tasks. Experience working with COMSOL is necessary. Experience working in Ansys, PyBaMM, and general Python knowledge are strong pluses. Previous experience building 1D PDE/ODE models from first principles and manually implementing them is a strong plus (e.g., NumPy implementation for Gummel iteration, Newton iteration, segregated solver). Ability to formulate coupled multiphysics models from first principles, including governing equations, assumptions, constitutive relationships, source terms, and boundary/initial conditions, prior to software implementation is a must. Familiarity with agentic code development concepts and the limitations of LLMs is a plus. The candidate should be someone who stays up to date on the latest continuum‑scale modeling approaches. Rapid learner and self‑motivated individual who takes ownership in a collaborative start‑up environment. Excellent communication, negotiation, and organizational skills with strong attention to detail. Physical Requirements Prolonged periods of time in front of a computer. Some physical data retrieval (e.g., from non‑networked computers located within the Solid Power buildings). Salary Range $105,000 - $140,000 annually Benefits Solid Power offers a comprehensive benefit package that includes medical, dental, and vision insurance; employer paid Life/AD&D/STD/LTD insurance; 401(k) with company match; 8 paid holidays plus the week between Christmas and New Years off; Unlimited PTO; up to six weeks paid FMLA leave; cell phone reimbursement; and eligibility to participate in bonus and equity plans. Export Control Requirements This position could require access to technology, software, and other information that is subject to governmental access control restrictions, due to export controls. Employment in this position is conditioned on the continued availability of government authorization to authorize release of such items, to the extent required, including without limitation an export license or other documentation required to establish authorization to receive such items. Equal Opportunity Employer As set forth in Solid Power’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law. #J-18808-Ljbffr
