Space Situational Awareness Engineer

About the Position

Space Situational Awareness Engineer

OKAPI:Orbits GmbH is at the forefront of space sustainability, addressing some of the most pressing challenges of the space industry: the growing problem of crowded orbital regimes, and the need for more efficient satellite operations. We are seeking a Space Situational Awareness Engineer to join our team in Barcelona or Madrid. In this role, you will develop cutting-edge algorithms for space sustainability, ensuring safe and sustainable space exploration.

Responsibilities

• Collaborate with a multidisciplinary team of aerospace engineers, data scientists, and software developers to integrate and optimize third-party sensor data sources within our SSA platform.
• Integrate third-party data sources into our platform, working closely with providers to seamlessly onboard their data.
• Develop, implement, and optimize high-precision algorithms for orbit propagation, orbit determination (OD), sensor fusion, covariance modelling, and uncertainty quantification.
• Develop methods to fuse data from diverse sources into one common image of the space debris environment.
• Conduct validation and verification (V&V) campaigns to benchmark and refine algorithmic performance against ground truth datasets.
• Work closely with software engineers to transition prototype algorithms into scalable, production-ready solutions.

Requirements

Must-have:

• M.Sc. or higher in Aerospace Engineering, Space Engineering, Applied Mathematics, Applied Physics, or a closely related field, or have prior work experience in the field of SSA/SST and related.
• A minimum of 5 years of relevant work experience is required. However, candidates with outstanding profiles may be considered with at least 3 years of experience.
• Strong theoretical and practical knowledge of astrodynamics, orbital mechanics, and flight dynamics.
• Experience in scientific programming using at least one of the following languages: Java, Fortran (90+) or Python.
• Ability to work in a fast-paced, collaborative, and research-driven environment.
• Valid working permit for Spain/EU.

Nice-to-have:

• Hands-on experience with space surveillance and tracking (SST) systems, including sensor tasking and catalog maintenance.
• Experience working with space agencies or private space companies in the SSA/SST field.
• Familiarity with space surveillance and tracking systems.
• Understanding of space policy and compliance frameworks.
• Experience with AI/ML applications for anomaly detection, pattern recognition, or orbit prediction in SSA applications.
• Interest in contributing to the sustainability of space and long-term spaceflight operations.

We Offer

• Work on groundbreaking space sustainability challenges with a team of top-tier engineers and scientists.
• Flexible work hours and the ability to choose between working from our office in Braunschweig, Madrid, or Barcelona.
• Enjoy technical freedom. Influence system architecture, research methodologies, and data integration approaches.
• Grow continuously with access to training budgets, industry conferences, and networking opportunities.
• Be part of a strong engineering culture, with regular knowledge-sharing sessions, technical deep dives, and innovation sprints.
• Great team spirit, with company-wide events and social activities like laser tag, dinners, and team-building outings.
