Job summary

Form Energy is seeking a Staff Simulation Engineer specializing in CFD and thermal systems to guide the modeling framework from R&D to pilot to full-scale deployment. You will own the thermal-fluid strategy, multi-scale simulations, and predictive modeling standards ensuring safety, durability, and grid readiness of 100-hour iron-air systems.

Relocation assistance is available. You will lead high-fidelity CFD development, validate models with empirical data, and drive automated workflows across

Qualifications

• Bachelor's or higher in thermal-fluid sciences with 8+ years of related work experience, or advanced degrees with relevant industry exposure.
• Deep technical expertise in CFD codes and meshing software such as Ansys Fluent, Star-CCM+, or Comsol Multiphysics.
• Strong grounding in conjugate heat transfer, fluid dynamics, multiphase flow, and closed-loop cooling systems.
• Proficient in Python or MATLAB to post-process, visualize, and automate large multi-physics datasets.
• Experience translating simulation results into actionable hardware-level requirements.
• Ability to build cross-functional networks for design trade-offs alignment.
• Curiosity and drive to understand complex physical phenomena from microscale to grid integration.
• Pragmatic, fast-iteration problem solving for design ambiguity.

Responsibilities

• Architect high-fidelity CFD and transient thermal modeling across scales from micro-cell fields to macro containerized systems.
• Validate physics-based models against empirical data with test and instrumentation teams.
• Develop automated simulation and optimization workflows to evaluate fluid routing, pressure drops, and cooling loop efficiencies.
• Collaborate with electrochemical, mechanical, and power electronics teams to resolve thermal-fluid anomalies.
• Select methodologies, mesh structures, and boundary conditions to identify hot spots and thermal risks.
• Standardize internal modeling workflows and conduct peer design reviews for simulation excellence.
• Identify toolset limitations and build robust, custom tools to remove engineering blockers.
