Software Engineer - Full Stack (Frontend Focus)

Software Engineer - Full Stack (Frontend Focus) Location Team What we're looking for We’re looking for a creative, product-minded engineer who thrives at the intersection of frontend engineering and AI developer experience. You’ll lead the design and implementation of intuitive, powerful interfaces that make training, fine-tuning, and evaluating AI models seamless and engaging. The ideal candidate obsesses over the details that make complex systems feel approachable — from thoughtful data visualizations to smooth real-time interactions. You care deeply about usability, accessibility, and creating delightful workflows that empower both expert AI engineers and newcomers alike. Responsibilities Lead the design and development of user-facing features for our AI training, fine-tuning, and RL platforms. Collaborate with product, design, and ML teams to translate complex workflows into intuitive, elegant interfaces. Implement real-time dashboards, visualizations, and interactive tools for model training and evaluation. Build and maintain performant, accessible, and responsive UIs that scale to handle large datasets and rich visual components. Develop frontend infrastructure — component libraries, design systems, and developer tooling — that speed up feature delivery. Integrate backend APIs and optimize data flow between frontend and ML systems. Stay ahead of modern frontend technologies and advocate for UX best practices across the company. Qualifications Strong experience with modern frontend frameworks (React preferred, Vue/Angular acceptable) and TypeScript. Proven track record of designing and implementing complex, data-rich web applications. Proficiency in crafting responsive, accessible, and pixel-perfect UIs. Experience integrating with REST or GraphQL APIs and handling real-time data (WebSockets, streaming APIs). Strong understanding of state management, component architecture, and performance optimization in large applications. Comfort working with backend services (Node.js, Python, or Go) to support full-stack feature development. Bonus: Experience building developer tools, visualization dashboards (D3.js, Plotly, ECharts), or AI/ML interfaces. Bonus: Familiarity with AI workflows, LLM fine-tuning, or reinforcement learning concepts.
