Senior React Front-End Developer to build a PWS offline-cabable mobile applications using React, TypeScript, and AWS

This role is % remote and requires you to work MST hours.

About the Role

We're looking for a Senior React Front-End Developer to join a high-performing engineering team building a React-based mobile application that extends an existing enterprise platform used by plant operations.

The application must support offline operation, allowing users to continue working when network connectivity is unavailable and seamlessly synchronize data once connectivity is restored.

This is an opportunity to work on a technically challenging enterprise application where performance, reliability, and user experience are critical.

Must Have

  • 8+ years of front-end software development experience.
  • Expert-level React and TypeScript development.
  • Experience building production-grade React mobile applications.
  • Demonstrated experience developing offline-capable mobile applications, including local data persistence, synchronization when connectivity is restored, conflict handling, and resilient user experiences in environments with intermittent or no network connectivity and PWA
  • Experience integrating RESTful APIs.
  • Experience developing enterprise applications hosted within AWS.
  • Experience with AG Grid.
  • Strong JavaScript, HTML, CSS, Git, and GitHub experience.
  • Excellent communication skills and the ability to thrive within a collaborative, high-performing engineering team.

Nice to Have

  • Experience using AI-assisted development tools such as GitHub Copilot or Claude Code as part of modern software development practices.
  • Experience with React Query.
  • Experience with Material UI (MUI).
  • Experience with AWS Cognito and/or AWS Amplify.
  • Experience with GitHub Actions or CI/CD pipelines.
  • Experience supporting manufacturing, industrial, or plant operations environments.
