Full job description

Aim high, go beyond!

At Open Cosmos we are solving the world’s biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before - ready for the challenge? Then read on…

Working in our Data Division

At Open Cosmos, our Data division transforms satellite data into meaningful insights that drive real-world impact. The team delivers all data products generated by Open Cosmos and its partners, curates and develops DataCosmos (our geospatial data platform) and builds integrations that make satellite imagery easy to access and act on.

What will you be doing?

As a Senior React Fronted Developer in the Data Team you will lead the design and development of the interfaces that bring the DataCosmos platform to life — building performant, scalable UI components and data visualisations that make complex satellite data clear, accessible, and actionable for users across the platform.

You’ll be:

Designing, developing, and maintaining React-based user interfaces for data exploration, visualisation, and delivery
Building intuitive and performant UI components to handle large and complex datasets
Implementing reusable, scalable front-end architecture and component libraries
Translating data requirements into clear, accessible, and user-friendly interfaces
Working closely with data and backend engineers to integrate APIs and data services effectively
Optimising front-end performance when handling high-volume or real-time data
Writing and maintain unit and integration tests to ensure reliability and robustness
Participating in code reviews, ensuring adherence to front-end best practices and coding standards
Contributing to CI/CD pipelines for front-end deployment and release
Providing technical guidance on React architecture, state management, and data handling patterns
Acting as a subject matter expert for front-end development within data-driven applications
Identifying opportunities to simplify, optimise, and enhance data visualisation and UI performance
Ensuring front-end solutions support clarity, usability, and efficiency for both technical and non-technical users

What You’ll bring

Strong proficiency in React and TypeScript, with the ability to design scalable and maintainable front-end systems
Deep understanding of modern front-end development practices, including HTML, CSS, and component-based architecture
Strong capability in building data-driven interfaces and working with APIs and asynchronous data flows
Confident use of state management approaches like Redux, Zustand, Context, or similar
Familiarity with data visualisation libraries (e.g. D3.js, Recharts, or similar)
Strong understanding of front-end performance optimisation, particularly for large or complex datasets
Understanding of CI/CD concepts and cloud-native environments
Ability to structure, transform, and present complex data effectively in the front end
Strong understanding of version control systems (Git) and collaborative development practices
Clear and effective communication, with the ability to work across technical and non-technical teams
Ability to take ownership of front-end architecture, overall user experience and setting high standards for code quality, usability, and performance.
Proactivity in identifying and driving improvements across systems and workflows and providing guidance and support to other engineers, contributing to team capability
A collaborative and solution-oriented approach, working effectively across disciplines, operating in a fast-paced, scaling environment with evolving priorities

This role can be based in any of our locations.

To apply, you must have the legal right to work in our chosen location.

When applying, please submit your CV in English.
