Senior Reactor Modeling Engineer

Senior Reactor Modeling Engineer

Lydian is looking for a Senior Reactor Modeling Engineer to conduct multi-physics modeling/simulation and data analysis. You will develop thermofluid models of Lydian's reactors and apply to them to various design, optimization, and experimental troubleshooting challenges. You will collaborate with experimentalists to gather data to validate your models, and will work with teams across the company as a lead for data handling and advanced data analysis.

We are looking for someone with strong fundamentals in heat transfer, fluid mechanics, thermodynamics, and chemical reaction kinetics who can confidently synthesize multi-physics models. Our ideal candidate can reliably assess a physical system and then craft CFD and/or analytical models that accurately capture its behavior. You need to have a strong background in data analysis and experience providing data and model-driven insights to designers and experimentalists.

• Develop thermofluid/reaction models of Lydian's custom-designed reactors
• Perform detailed analyses (hand calculations, FEA, CFD, etc.) to support design and optimization of critical reactor components
• Leverage models to sharpen our understanding of experimental systems, aiding with troubleshooting, design of experiments, and selection of process parameters
• Collaborate with teammates to design, build, and execute tests to obtain experimental data for model validation and parameter extraction
• Develop data analysis methods to support teams across Lydian
• Collaborate with process engineers to implement parametrized reactor models in plant-level simulations

• BS, MS, or Ph.D. in Mechanical Engineering, Chemical Engineering, or similar. MS or Ph.D. are preferred
• 5+ years of experience in analysis of thermal fluid, reactor, or catalytic systems
• Experience using CFD software (Ansys, COMSOL, OpenFOAM, STAR-CCM+, etc.) to analyze physical systems and guide product design
• Skilled at analyzing experimental data, drawing meaningful conclusions, and presenting findings to a broader team
• Strong ability to apply engineering principles—including thermodynamics, fluid mechanics, and heat and mass transport—to systematically approach complex design problems
• Experience modeling reactors and chemical kinetics
• Comfortable working independently to define and execute projects

• Challenging, collaborative, and meaningful work and an important voice in company development
• Competitive salary commensurate with experience
• Meaningful equity compensation
• Unlimited PTO and expectation that all employees take significant time off to rest, recharge, and enjoy life outside work
• Excellent insurance with 100% of healthcare, vision, and dental premiums covered for the employee, and 80% coverage for dependents
• 401(k) with company match
