Full job description

Aim high, go beyond!

At Open Cosmos we are solving the world’s biggest challenges fro 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 Chief Technology Office (CTO)

The CTO division is where Open Cosmos technology comes to life. Covering engineering, product development, and technical innovation, the team designs, builds, and operates the satellites, systems, and platforms that make our missions possible. It’s a highly collaborative environment where ideas become real hardware, software, and data solutions that deliver impact from space.

Our Ground Segment team builds and runs the software that powers Open Cosmos missions. From our cloud-native Mission Operations Centre (MOC) to customer-facing tools, they design, deploy, and operate the systems that keep multi-satellite constellations flying.

Working with modern technologies — microservices, Kubernetes, Go, RabbitMQ, Postgres, and Terraform — they follow an agile, DevOps-driven approach. Every engineer owns their work end-to-end, from design and code to testing and operations, with plenty of space to suggest improvements and shape how they work.

What You'll Be Doing

As a Junior Front End Engineer, you’ll design, build, and optimise the mission operations user interface that powers Open Cosmos satellite missions. You’ll write and ship production-ready React code, implementing features that improve usability, performance, and scalability.

You’ll work closely with operators, designers, and product owners to turn requirements into clear, intuitive user interfaces. You’ll review code, champion React best practices. As our software grows, you’ll tackle performance challenges, improve reliability, and continuously enhance our tools, processes, and CI/CD workflows.

What You’ll Bring

We care more about what you can do than where you learned it — if you’re excited by the mission, we’d love to hear from you even if you don’t tick every box.

To thrive in this role, you’ll bring:

Programming skills in React and TypeScript, with a focus on building clean, maintainable, and scalable applications.
Exposure of working with state management solutions like Redux, Zust and, or Context API.
The ability to write and maintain unit and integration tests to keep components reliable.
A understanding of front-end performance optimisation techniques and when to apply them.
Working with CI/CD pipelines to support smooth and reliable deployments.
The ability of promoting React-specific best practices and improving front-end workflows.
Clear, collaborative communication — able to partner effectively with designers, product owners, and backend engineers.

For this role you can be based in any of our locations:

Harwell, UK
Barcelona, Spain
Porto, Portugal
Athens, Greece
Tenerife, Canaries

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

Why Open Cosmos?

Work at the cutting edge of space technology with customers around the globe.
A mission-driven company making space accessible to help solve real-world challenges.
A diverse, ambitious, and supportive team.
