Job Title: Model & Applications Developer

Location: Lake Forest, CA / Houston, TX

Employment Type: Full-time

The Job

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.

Key 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

Essential 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

Desired Skills and Competencies

• 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

USA Benefits include:

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, vision, and 401K.

It's possible we're hiring for this position in multiple countries, in which case the above benefits apply to the primary location. Specific benefits vary by country, but our packages are similarly comprehensive.

Hybrid working

We work in a hybrid way at AVEVA. Most roles are based at a local AVEVA office, with an expectation of being on-site 50% of your working hours to support collaboration and connection. Some positions are fully office-based depending on the nature of the work, and certain roles that support specific customers or markets may be remote. The working arrangement for this position will be confirmed during the hiring process.
