As a Senior Software Developer at Vention…

• Support and mentor team members, elevating engineering standards and driving excellence in front-end craftsmanship.
• Analyze and refactor legacy code, improving architecture, performance and maintainability of MachineBuilder’s codebase.
• Provide clear APIs and interfaces for other teams (e.g., Simulation, MachineLogic) and support internal product-engineering partnerships.
• Utilize linear algebra and 3D tools to support model manipulation, snapping, selection, layering and real-time performance.
• Collaborate with Design, Product and Engineering teams to prioritize new features and drive innovation in user experience.
