ROLE DESCRIPTION As a Senior Fluids Analysis Engineer specializing in Computational Fluid Dynamics (CFD), you will play a critical role in bringing Form Energy's multi-day energy storage systems from R&D and pilot stages to full-scale commercial utility deployment. You will own physics-based modeling to inform architectural strategies and design details for our Electrolyte, Thermal, Hydrogen, and Air Delivery Systems within our 100-hour iron-air battery systems. Your technical ownership will directly enable the optimization of system-level architectures, ensuring safe, predictable operation and long-term grid stability. Relocation assistance is available. Relocation assistance is available. WHAT YOU'LL DO: - Build high-fidelity computational fluid dynamics (CFD) and transient thermal modeling strategies across multiple physical scales, spanning from micro-scale electrochemical cell fields to macro-scale containerized systems. - Validate and anchor numerical physics-based models against empirical data, collaborating with test and instrumentation teams to close the gap between simulation and physical testing. - Support the development of automated simulation and optimization workflows to systematically evaluate fluid routing, pressure drops, and cooling loop efficiencies. - Partner with electrochemical, mechanical, and power electronics teams to resolve complex, multi-factor thermal-fluid anomalies during product integration. - Suggest and exercise judgment in selecting simulation methodologies, mesh structures, and boundary condition assumptions to proactively identify hot spots and thermal risks. - Drive the standardization of internal modeling workflows and establish rigorous peer design reviews to ensure technical simulation excellence. - Model initiative by identifying limitations in our physics-based toolsets and building customized, robust tools to eliminate engineering development blocks. WHAT YOU'LL BRING: - Experience with a Bachelor's degree and 5+ years of related work experience, or a Master's degree and multiple years of experience, or a PhD with deep focus on thermal-fluid sciences and some industry experience. - Deep technical expertise in commercial computational fluid dynamics codes and meshing software, such as Ansys Fluent, Star-CCM+, or Comsol Multiphysics. - Strong foundational knowledge of conjugate heat transfer, fluid dynamics, multiphase flow, and closed-loop cooling systems. - Applied experience using scripting languages like Python or MATLAB to post-process, visualize, and automate massive multi-physics datasets. - Demonstrated track record of translating complex simulation results into actionable, physical system-level requirements that guide design decisions. - Ability to build formal networks outside your immediate area of expertise to achieve technical alignment on multi-variable design trade-offs. - Intellectual curiosity that drives a continuous pursuit of understanding novel, complex physical phenomena from the microscale to complete grid integration. - Pragmatic problem-solving skills to navigate design ambiguity and balance modeling fidelity with rapid execution speed. - Thriving on complexity and enjoying the challenge of decomposing abstract, highly integrated physical problems into clean, high-performing thermal systems. #LI-Onsite #LI-EH1 Humanity is a cornerstone of Form Energy’s culture, and we make sure our compensation and benefits reflect that.
