We design products focused on impact, fast delivery, and continuous improvement. Inspired by the digital world, we are firmly customer-oriented and driven by an entrepreneurial spirit.

We manage risks to push boundaries and achieve results that would not be possible within a traditional space model.

We deploy every necessary resource to support the development of our products, whether in propulsion or in-orbit services. Strengthened by an innovative mindset inherited from our early days, we are preparing to grow into an ambitious industrial company.

📌Contribute to Frontend Development - Participate in the development of modern web interfaces (React) to visualize data, analysis results, and operational indicators in a clear and usable way ;

📌 Own Tooling & Delivery Pipelines - Contribute to the CI/CD ecosystem (GitLab, GitLab CI), containerization (Docker), and deployment environments (Kubernetes), ensuring smooth development, testing, and deployment cycles.

In this mission you will use technologies such as ClickHouse, PostgreSQL, Pandas, NumPy, Apache Arrow, Prefect, and Flink to build scalable data processing and analysis workflows.

Preferred Experience 💁‍♀️

📌 3–5 years of experience as a software developer, with a strong focus on Python.

📌 Experience (or strong interest) in React and modern frontend development.

📌 Solid understanding of data processing and analysis workflows, as well as ability to design clean APIs and maintainable software architectures.

📌 Hands-on experience with databases (ClickHouse, PostgreSQL) and data-oriented libraries (Pandas, NumPy).

📌 Familiarity with CI/CD pipelines, GitLab, Docker, and Kubernetes.

📌 Comfortable working in English (B2) in a technical, multicultural environment.
