Model & Applications Developer
AVEVA•Lake Forest, CA
•$87,400 - $153,900•Hybrid
About The Position
The Model & Applications team is responsible for developing and maintaining the first-principles mathematical models at the core of AVEVA Process Simulation. Using an equation-oriented solver architecture, we deliver rigorous equipment models that serve customers across refining, chemicals, renewables, and beyond. As part of this team, you will work at the intersection of chemical engineering, applied mathematics, and software development contributing to models that run in steady-state, dynamic, flow-driven, and pressure-driven simulation modes.
Requirements
- B.S., M.S., or Ph.D. in Chemical Engineering (or equivalent demonstrated experience in process modeling)
- Ability to derive and formulate systems of equations from first principles (mass, energy, and momentum balances)
- Strong foundation in transport phenomena and thermodynamics
- Familiarity with equation-oriented or simultaneous-equation solving approaches
Nice To Haves
- Experience with process simulation platforms (AVEVA, Aspen, etc.) and understanding solver convergence behavior
- Programming (Python, C++, C#, or similar) with experience working in a shared codebase using version control (e.g., Git)
- Breadth across multiple process domains (separations, reaction systems, heat exchange, pressure networks) with the ability to develop expertise in unfamiliar areas
- Ability to communicate complex mathematical and engineering concepts clearly to cross-functional stakeholders including developers, product managers, and customers
- A record of initiative and independent problem-solving: research contributions, open-source development, or self-directed technical projects
Responsibilities
- Develop, maintain, and improve first-principles mathematical models for simulating chemical process equipment in both steady-state and dynamic modes
- Implement model equations within a collaborative environment using standard Agile software development practices including version control, pull requests, and automated testing
- Diagnose and resolve complex simulation issues escalated from technical support, applying subject matter expertise to identify root causes
- Collaborate within multidisciplinary squads alongside software developers, thermodynamicists, and solver/optimization engineers to deliver new simulation capabilities
Benefits
- Flex work hours
- 20 days PTO rising to 25 with service
- three paid volunteering days
- primary and secondary parental leave
- well-being support
- medical
- dental
