Job summary

Invisix is seeking a Geometry Modeling Engineer to define how our modeling tool describes 3D structures and evolves: from requirements to geometry engine changes. You’ll work across application, algorithm, and software teams, translating use cases into specifications and guiding implementations through reviews and acceptance.

You will shape how geometry models are handed to simulation software and assess the impact on measurement results.

Qualifications

• MSc or PhD (or comparable experience) in a relevant field with 3–5 years of experience.
• Experience with computational geometry and geometry engines or CAD kernels.
• Hands-on work building 3D parametric models used in simulations or device modeling.
• Experience preparing geometric models for physics solvers (FEM/TCAD).
• Python proficiency for prototyping and collaboration with software teams.
• Fluent English.
• Active use of AI tooling to enhance workflows.

Responsibilities

• Translate application use cases into modeling requirements and specify supported structures and features.
• Identify gaps in the modeling tool and propose extensions to the geometry engine.
• Add geometric freedom (rounded corners, freeform profiles) while keeping models valid for simulation.
• Evaluate whether extending the current tool or building a new one is more viable.
• Define how geometry models are handed over to simulation software and how choices affect results.
• Prototype new capabilities and guide implementation through specs, reviews, and acceptance.
