Platform-Integrated Process Modeling Engineer

Riven Systems; New York (NY); On-site; USD 120,000 - 190,000; Full time

Job summary

Riven Systems seeks a Process Modeling Engineer to build the layer connecting the platform to operating plants. You will collaborate with experts in thermodynamics, hydrometallurgy, ML, and autonomous experimentation to model flowsheets with industry-leading rigor.

Responsibilities include developing the programmatic modeling layer, designing a composable architecture with validation, and systematizing initialization, scaling, and solving of models.

Qualifications

• PhD or equivalent in Chemical Engineering, Operations Research, or related field.
• Experience building process models, including unit operation models and diagnosing convergence failures.
• Fluency with equation-oriented modeling and large-scale nonlinear optimization, including initialization, scaling, and degrees of freedom.
• Working knowledge of hydrometallurgical unit operations, or comparable separations experience.
• Views on how process modeling changes when the caller is an agent rather than an engineer at a terminal.
• Comfortable with the tools and processes for building large software systems.
• Clear interdisciplinary communication and the curiosity to learn quickly in new domains.

Responsibilities

• Develop Riven’s programmatic process modeling layer where models can be written by humans or agents.
• Design a composable model architecture with rigorous flowsheet validation.
• Systematize the initialization, scaling, and solving of process models.
• Connect the process layer to thermodynamic modeling.
• Build the paths that carry operational data from pilots and customer deployments back into the platform.
• Establish continuous validation and regression testing across a growing model library.
