Responsibilities
You'll own the design, implementation, and delivery of the APIs that connect our implicit modeling and simulation application with the ecosystem of tools our customers use to map their workflows—from third-party enterprise systems and automation scripts to custom integrations and ML/generative AI training pipelines. These APIs integrate directly with our core geometry and modeling system as well as our UI layer. You'll own critical parts of these systems and collaborate closely with engineers focused on the core engine and UI development. As technical owner of these strategically critical interfaces, you'll understand customer workflows, identify integration opportunities, and translate requirements into robust, scalable C/C++ solutions
You'll work within an established desktop application codebase while helping modularize it toward a more open, service-oriented architecture. This means balancing the immediate delivery of user-facing features with thoughtful consideration of long-term architectural improvements
You'll participate in technical design discussions, code reviews, and knowledge-sharing sessions, helping to elevate the team's collective expertise and establish best practices for integration development and architectural modernization
