Zingle AI Research Lab is a San Francisco based deep-tech startup building an AI-native platform for modern analytics teams. We are backed by Accel and Nexus, two of the world's leading data and enterprise investors.

Our team includes AI PhDs, researchers, senior technologists, and serial entrepreneurs.

We're looking for a Founding Frontend Engineer who wants to own the entire user-facing surface of a complex AI product and shape how modern data teams interact with it.

This is a builder role. You will translate product ideas into polished, production-grade interfaces - not stitch together templates or component libraries.

Responsibilities:

Build clean, responsive, and reusable frontend interfaces using React
Own the full frontend stack - from component architecture to API integration to deployment
Work closely with backend and AI engineers to design frontend data flows for complex, real-time systems
Turn product requirements and rough ideas into clear, usable UI concepts
Create wireframes or Figma mockups for new features before writing code
Build internal tools, dashboards, and workflows that make the platform intuitive for data and analytics teams
Contribute to small backend features in Python and CRUD API operations when needed

Requirements:

2 - 4 years of hands-on frontend development experience
Strong proficiency in React and component-based architecture
Comfortable working with REST APIs and managing frontend data flows
Good eye for responsive UI, layout, and interaction design
Plus: Can write Python and handle basic CRUD API operations
Big plus: Ability to create wireframes or Figma designs and translate ideas into clear UI concepts before building them

Location: Bengaluru (in-person)

Compensation & Benefits:

Competitive compensation with meaningful ESOPs
Work directly with founders, AI researchers, and senior engineers
Opportunity to build core IP at an early-stage, high-bar deep-tech startup
Long-term ownership and visibility across product, AI, and engineering
