Senior ReactJS Developer - SaaS Product

Are you an expert with ReactJS and its ecosystem?

Are you available immediately?

If yes to both, your ReactJS expertise is needed within this South West London based SaaS company!

As Senior ReactJS Developer, you will be able to make decisions such as which libraries to use, how state management should work, be able to build flexible React components, build state management and API layers, and help the company identify patterns and common functionality.

This SaaS company are breaking boundaries with technology in order to improve the customer experience for millions. They are rapidly growing and are a completely self-funded company producing state of the art, multi-channel SaaS products for their customers, with over 2 million users every month.

They need a highly technical Senior ReactJS Developer to help them build a flexible, tested, and well-documented framework for the admin interface of their customisable SaaS product. The admin interface includes elements such as filterable and sortable tables, grouped lists, data-heavy grids with inline editing, dynamic forms, and more.

This project is being shipped in 6 weeks and will be a success when you have built a fully functioning, fast, stable and testable admin interface for their product that can be easily maintained and built upon, with a finite set of flexible components and models that they can use everywhere.

Other developers will be able to take these components to build new product features very easily and new developers can join the team and be immediately productive without a steep learning curve.

You will need to be comfortable working independently with a high level of responsibility, as most of the team are backend focused. A background in a start-up environment would be beneficial.


  • Expert with ReactJS and the ecosystem. Your expertise will be needed to make decisions such as which libraries to use, how state management should work, etc.
  • Good written skills. You will help write documentation on how to use the components and framework you build.
  • Expert with testing and TDD. They expect their codebase to be highly testable and expect the developer experience to be based on TDD.
  • This project will be written in TypeScript. Prior experience with TypeScript is a plus.
