Indra Space – Leading the Next Generation of Space Systems
At Indra Space, we are on a mission to redefine the European space industry by delivering high‐performance small satellite solutions for LEO missions. Our ambition is to become a leading company in end‐to‐end satellite systems, driving innovation in Space Domain Awareness, Space Traffic Management, Science & space exploration.
As the Space Business Unit of Indra Group, we combine cutting‐edge technology with a full value chain approach—from satellite design and integration to ground segment and operations. With the integration of Deimos and strategic participation in Hispasat and Hisdesat, we are scaling Europe's space autonomy and contributing to flagship programs like IRIS2, Galileo, EGNOS, and Copernicus.
What are we looking for?
Experience of at least 5 years in the following:
Developing or using simulation frameworks for complex systems in the space domain
Developing SSA algorithms: sensor simulation, cataloguing, KPI analysis and deep knowledge of orbital mechanics




Hands‐on experience with end‐to‐end simulation workflows
Supporting system validation, verification, and performance analysis through simulations
Development in Java, Python, Fortran, C
Knowledge of Continuous Integration/Continuous Delivery
Experience in new technologies such as Artificial Intelligence and high‐availability systems
Experience with numerical methods, stochastic modelling, and performance analysis
Experience with CCSDS standards
Experience with event‐driven and time‐step simulations
Experience with sensor modelling, including noise, detection thresholds, FOV, and observation uncertainties
Experience with data cataloguing and tracking systems: storing, querying, and updating object catalogues
Familiarity with API development / integration for simulation systems
Use of tools like Git, Gitlab pipelines, Jira and Confluence
Don't worry if you don't meet 100% of the requirements. Apply, learn about our proposal, and show us what y
