Interested in leading the UI architecture for a SaaS platform powering the future of web-based engineering and simulation? This role is focused on leading the architecture of React/TypeScript-based frontend systems that can support complex simulation workflows, real-time data visualization, plugin extensibility, and future AI/ML integrations. The platform enables engineers to upload CAD models, run simulations in the cloud, visualize results directly in the browser, and integrate AI-driven optimization into their workflows. Your experience building front-end systems, strong state management practices, and maintaining system clarity is critical. You should be passionate about building extensible UI platforms and thinking systematically about how front-end architecture supports a growing technological ecosystem. Experience in simulation environments, CAD, 3D visualization, or scientific data workflows is a plus but not required. What matters most is strong front-end system design experience, a clear understanding of scalable web application architecture, and excitement about building modern interfaces for technical users. This is a full-time, hybrid position based in the San Francisco Bay Area. Compensation is dependent on experience and expectations, with a base salary range of $200K–$275K plus equity. No resume required. No C2C.
