About the Role:

Unico Connect is an AI-first technology partner that builds custom mobile, web, and AI products for clients across multiple geographies.

We are hiring a Frontend Engineer who will build production-grade web applications across customer engagements, partnering closely with designers, backend engineers, and AI engineers.

The mandatory requirement for this role is hands-on production experience shipping React applications, with ownership of at least one feature area end to end including state, API integration, and testing.

The role is hands-on.

Expect to implement complex flows, integrate with backend and AI services, contribute to a shared design system, write tests, and review the work of others.

A typical week includes a design handoff review, implementation of a new flow, a code review session, and a working call with a backend engineer on API contracts.

Responsibilities:

Production UI Development

Build production-grade React UI for customer engagements, including complex forms, dashboards, data-dense views, and AI-driven interactions.

API Integration

Integrate with REST and GraphQL APIs.

Handle authentication, streaming responses (Server-Sent Events, WebSockets), retries, and graceful error states.

State Management

Build state architecture using Redux, Zustand, Jotai, or equivalent.

Handle async state, optimistic updates, and cross-component coordination.

Design System Contribution

Implement components within an established design system.

Maintain token discipline and contribute back to shared components.

Testing

Write unit, integration, and end-to-end tests using Jest, React Testing Library, and Playwright or Cypress.

Performance and Accessibility

Profile and optimise rendering and bundle size.

Apply WCAG 2.1 AA practices in everyday work.

AI-Assisted Development

Use Claude, Cursor, and similar tools day to day.

Build discipline for reviewing and validating AI-generated code.

Requirements:

Hands-on Production React Experience (Mandatory)
