About The Position

We are looking for a Frontend Engineer who thrives in a fast-paced, high-ownership startup environment. This is a hands-on role for a self-starter who can take ownership of the user experience from concept to deployment, iterate quickly based on feedback, and optimize for speed, usability, and performance. You will design and build sophisticated UI components, interactive dashboards, and data visualizations that directly impact end users. If you love solving challenging UI problems, shipping polished interfaces at startup speed, and working in a collaborative, low-ego environment, this role is for you.

Requirements

3–5 years of React development with advanced patterns (custom hooks, complex state management, performance optimization, client/server-side separation).
Expertise in TypeScript (complex generics, utility types, strict typing in production applications).
Strong experience with the modern React ecosystem (Next.js App Router, SSR, data fetching and global state management libraries).
Proven track record in enterprise UI development (component libraries, design systems, accessibility standards).
Performance optimization skills (memoization strategies, render optimization, virtualization).
Strong problem-solving skills and ability to execute quickly with minimal guidance.
Experience working in agile, fast-paced startup teams.

Nice To Haves

Experience with data visualization (charts, graphs, interactive dashboards).
Real-time UI patterns (WebSocket integration, live updates, optimistic UI).
Enterprise authentication (SSO, role-based access control, session management).
Experience integrating AI/ML models into production applications.
Familiarity with building developer-facing tools (code editor integrations, syntax highlighting, diff viewers).

Responsibilities

Rapid Feature Development & Deployment Build sophisticated data visualization interfaces, workflow management UIs, and real-time dashboards.
Design and maintain scalable component libraries with consistent design patterns.
Implement complex client-side state with optimistic updates and real-time synchronization.
Create intuitive UIs for AI model interactions, data pipeline management, and enterprise system integrations.
Optimize for speed, usability, and performance without compromising quality.
Performance Optimization & Scalability Continuously identify and fix performance bottlenecks in frontend systems.
Startup Mindset: Autonomy & Execution Speed Take initiative—identify problems and build solutions without waiting for direction.
Make trade-offs between speed and long-term maintainability based on business needs.
Work in a high-ownership environment, making architectural and UI design decisions as needed.
Quickly adapt to changing priorities, tight deadlines, and startup pivots.
