Your responsibilities:

Frontend (~80-90%)

• Build and iterate on React 19 interfaces-admin consoles, data grids, forms, workflow builders, and AI chat experiences.

• Implement real-time features using SignalR client for live chat streaming and data updates.

• Work with DevExtreme components for enterprise-grade data grids and UI elements.

• Build visual workflow editors using React Flow for diagram and node-based interfaces.

• Write clean component code with React Hooks (useState, useEffect, useCallback) and Context API for state management.

• Consume RESTful APIs with proper error handling, loading states, and optimistic updates.

• Style components with SASS/SCSS while maintaining responsive, accessible designs.

• Handle JWT authentication flows on the client side-login, token refresh, and protected routes.

Collaboration (10-20%)

• Work closely with backend engineers to define API contracts and data shapes.

• Debug integration issues across the stack-understanding how your UI connects to .NET services.

• Participate in code reviews and contribute to frontend architecture decisions.

• Ship via Docker and GitHub Actions; contribute to CI/CD improvements as needed.

Our expectations:

• 1-3 years of frontend development experience

• Solid React experience: hooks, component architecture, state management

• JavaScript ES6+ fluency-destructuring, async/await, array methods, modules

• CSS/SASS proficiency-you can style components, handle responsive layouts, and debug styling issues

• RESTful API consumption-fetching data, handling errors, managing loading states.

• Git version control-branching, merging, pull requests.

• Understanding of JWT authentication on the client side-login flows, token storage, protected routes

• Clear async communication skills-critical for remote collaboration

• Curiosity about AI and willingness to learn

What company offers you:

• Work on AI that ships

• Learn and grow fast. Work alongside senior engineers who will mentor you

• High ownership, low bureaucracy, small team, direct founder access

• Fully remote, async-first

• Competitive compensation

• Build real AI products
