Senior Frontend Engineer ($180k-$220k + Equity) at zaimler.ai

Jack & Jill/External ATS • San Francisco, CA

3d • $180,000 - $220,000

About The Position

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.

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.

Requirements

• 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.

Responsibilities

• 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.
