Frontend Developer (UI/UX)

VAST Data is the data platform company for the AI era. We are building the enterprise software infrastructure to capture, catalog, refine, enrich, and protect massive datasets and make them available for real-time data analysis and AI training and inference.

This is a great opportunity to be part of one of the fastest-growing infrastructure companies in history, an organization at the center of the revolution in artificial intelligence.

*"VAST's data management vision is the future of the market."* — Forbes

Our Iceland team is developing a next-generation cloud resource management platform that provides a unified API surface for managing infrastructure across multiple cloud providers. We're building systems that abstract complexity while maintaining the power and flexibility that enterprise customers demand.

Join us and discover just how VAST the possibilities are.

We're looking for a Frontend Developer to join our engineering team in Iceland and help build the administrative interface for our cloud resource management platform.

You'll work on a modern React application using the latest web technologies—React, TypeScript, and a custom design system. You'll translate complex backend APIs into intuitive user experiences, working closely with backend engineers to ensure the frontend is performant, type-safe, and delightful to use.

This is a highly hands-on role with significant autonomy. You'll own key features end-to-end, influence UI/UX decisions, and help define what "great" looks like for enterprise cloud management interfaces. You'll also be encouraged to leverage modern tooling—including AI-assisted workflows—to accelerate development while maintaining code quality.

What You'll Do:

- Build and maintain a modern React application with TypeScript for managing cloud resources and infrastructure

- Develop complex, data-heavy interfaces for enterprise-level resource management

- Work with OpenAPI specifications to generate type-safe API clients and integrate with backend services

- Design and implement reusable UI components following established design patterns and accessibility standards

- Collaborate with backend engineers to shape API contracts and ensure seamless frontend integration

- Implement secure authentication flows and session management

- Build responsive, performant interfaces that handle real-time data updates and large datasets

- Write comprehensive tests to ensure code quality and prevent regressions

- Optimize build performance and bundle size using modern development tools

- Contribute to the design system and component library to improve developer experience across the platform

- Participate in code reviews and help maintain high standards for code quality and consistency

- Leverage AI tools to accelerate development, debug issues, and explore solutions efficiently

Requirements

Required:

- Strong hands-on experience with React and modern JavaScript/TypeScript

- Solid TypeScript skills with understanding of advanced types and type safety

- Experience building data-heavy, enterprise-grade web applications

- Familiarity with modern state management patterns and data fetching strategies

- Understanding of RESTful APIs and asynchronous programming

- Experience with component-driven development and design systems

- Good eye for UI/UX and ability to translate designs into functional interfaces

- Comfortable taking ownership and driving features independently

- Good communication skills in English

Preferred:

- Experience with modern React patterns (hooks, context, server state management)

- Familiarity with OpenAPI/Swagger and API-first development

- Experience with modern build tools and development workflows

- Knowledge of OAuth2/OIDC authentication flows

- Experience with frontend testing strategies and tools

- Understanding of accessibility standards (WCAG, ARIA)

- Familiarity with monorepo structures and workspace management

- Experience working in early-stage or evolving product environments

- Strong comfort using AI-assisted development tools (GitHub Copilot, Claude Code, Cursor, or similar)

- Using AI for rapid prototyping, component scaffolding, and API integration

- Applying AI tools pragmatically to accelerate feature development while maintaining code quality

- Curiosity and openness toward integrating AI into day-to-day development workflows

- Full-stack capabilities (Go, Node.js, or similar backend experience)
