Job description

We're looking for a sharp, curious frontend engineer who loves solving problems and building intuitive, reliable user experiences. Whether you're early in your career or have years under your belt doesn't matter—what matters is that you're smart, you learn fast, and you genuinely enjoy the craft of building software. This isn't a role where you'll be siloed. You'll own frontend features from implementation through deployment, collaborate closely with product and backend engineers, and have real ownership over the experiences you build.

Our frontend stack revolves around React and TypeScript. You'll be building and maintaining web applications that turn complex workflows and data into clear, responsive, accessible interfaces, backed by services running on Azure.

Key responsibilities

Build and maintain frontend features using React and TypeScript

Translate product requirements into intuitive, responsive, accessible user interfaces

Develop reusable components and help maintain consistent UI patterns

Integrate backend APIs and collaborate with backend engineers on contracts and behavior

Own the quality of your work through testing, code reviews, and performance checks

Troubleshoot frontend issues and contribute to product support

Contribute to frontend deployments and delivery workflows

Support the team through collaboration, knowledge sharing, and constructive feedback

About you

React — you understand components, hooks, composition, and how to build maintainable applications

State management and data fetching — you know how to manage local and shared state, fetch and cache server data, and handle loading, error, and empty states

API integration — you can work with RESTful APIs, collaborate on API contracts, and handle authentication and failures gracefully

Component architecture — you build reusable components and consistent UI patterns without overengineering

Accessibility — you consider keyboard navigation, focus management, semantic HTML, and accessible interactions as part of building a good product

Frontend tooling and delivery — you're comfortable with package managers, build tools, Git, and CI/CD workflows

English is a must

Good to have

Tailwind CSS and design systems - a big plus - experience building and maintaining reusable component libraries and consistent UI patterns

Experience with tools such as React Testing Library, Vitest, or Storybook

Progressive Web Apps (PWAs) and offline-first experiences - experiences using service workers, caching, localStorage, and IndexedDB to keep apps useful without a connection, with reliable data synchronization when connectivity returns

Fronted observability, including error tracking an real-user performance monitoring

Experience with real-time updates, data-heavy interfaces, or complex forms

Familiarity with Azure, Docker, or backend development in C# or another object-oriented language
