Senior Frontend Engineer at zaimler.ai

Join a senior team founded by data veterans from Visa and LinkedIn to build the semantic context layer for autonomous AI agents. As a core frontend engineer, you will design and implement complex data visualizations and graph interfaces, transforming fragmented enterprise data into actionable domain intelligence for the next generation of AI.

Location: San Mateo, USA

Salary: $180k-$220k + Equity

Why this role is remarkable:

• Work directly with founders who built world-class data infrastructure at Visa and LinkedIn, tackling the "reasoning gap" that causes enterprise AI to fail.
• Massive technical ownership as a founding-era engineer, shaping the product architecture and UI/UX for a platform already deploying with major enterprise partners.
• High-growth trajectory at the intersection of Knowledge Graphs and Agentic AI, backed by top-tier VCs and solving a critical bottleneck in the AI stack.

What you will do:

• Architect and build the frontend Graph Semantic Layer using React and TypeScript to enable seamless interaction with complex network data.
• Collaborate with the CPO and lead designer to translate user research into high-fidelity, aesthetic interfaces for enterprise data discovery.
• Develop sophisticated data visualization components using D3 or similar libraries to help users map and understand domain relationships at scale.

The ideal candidate:

• 5+ years of industry experience with a proven track record of shipping high-quality data products or analytics dashboards in a fast-paced startup environment.
• Deep expertise in React, TypeScript, and modern data visualization libraries like D3, Recharts, or ECharts to handle complex client-side performance.
• Entrepreneurial mindset with the ability to drive technical decisions independently and a strong eye for detail in both code and aesthetic design.
