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

Our Data Division transforms satellite data into meaningful insights that drive real-world impact. Bringing together our Delivery, Image Processing, Data Platform, and Commercial teams, we develop and deliver high-quality data products, power DataCosmos - our geospatial platform - and ensure our solutions are accessible, valuable, and easy to use. By combining space technology, data science, and customer insight, the team helps organisations turn complex data into action and create positive change on Earth.

What will you be doing?

• Designing, implementing, validating, and maintaining satellite flight software
• Supporting ground tools, ensuring software is robust, traceable, and fit for the reliability demands of space missions
• Developing features for Linux and RTOS-based systems in line with mission and system requirements
• Participating in code reviews, testing campaigns, and CI/CD processes to ensure high software quality standards are maintained consistently throughout the development lifecycle
• Maintaining configuration control, documentation, and full software traceability throughout the development lifecycle
• Collaborating closely with Systems, Electronics, and Mission Operations teams to integrate and test subsystems, contributing technical expertise that supports effective cross-functional alignment and problem resolution
• Contributing to post-launch operations and build and integration activities
• Driving continuous improvement in architecture, design, and engineering processes, identifying and implementing changes that enhance software reliability, maintainability, and delivery efficiency

What You'll Bring

• Strong programming capability in Rust, or solid understanding in C or C++ with the motivation and ability to transition to Rust in a production environment
• Proficiency in compiled and object-oriented programming paradigms, with an emphasis on performance, reliability, and correctness
• Ability to work in Linux development environments, including scripting and command-line tooling, as part of day-to-day engineering work
• Familiarity with CI/CD pipelines and automation tools such as GitLab, Jenkins, Docker, and pytest, supporting consistent and efficient software delivery
• Ability to apply secure coding and fault-tolerant design principles to software development, ensuring reliability and resilience in mission-critical contexts
• Working knowledge of spacecraft subsystems including ADCS, EPS, communications, and payload systems, and how software interfaces with and supports each
• Awareness of European space engineering standards such as ECSS, and their practical implications for software development, documentation, and compliance
• Understanding of RTOS concepts and their application in embedded and space software environments
• Demonstrated familiarity with software verification and validation processes, including testing strategies and traceability requirements for mission-critical systems
• Awareness of fault detection, isolation, and recovery principles, and how these inform robust software design in space applications
