Senior Software Engineer - Space Systems

We continually strive to help our workforce achieve their professional and personal goals, engaging them in challenging and inspiring projects.

The Software Engineer will design, develop, and support advanced software systems for space telescope and laser platforms within EOS’s Space Systems division. This role focuses on delivering high-performance, reliable, and scalable software that enables precision space observation, tracking, and laser operations.
Working within a multidisciplinary engineering environment, the role contributes across the full software lifecycle, including development, integration, testing, and deployment, ensuring systems meet the demands of mission-critical observatory and space applications.
The position requires strong technical capability, adaptability to complex problem domains, and the ability to deliver robust solutions both independently and collaboratively within small, high-performing teams.

Primary duties

• Design, develop, integrate, and maintain high-performance software systems supporting space telescope and laser operations, ensuring reliable and efficient functionality through rigorous testing, system verification, and close collaboration with multidisciplinary engineering teams.

Key Responsibilities

• Design, develop, and maintain software systems supporting space telescope and laser operations
• Deliver high-quality, reliable, and high-availability software solutions for mission-critical environments
• Support system integration, verification, and validation within observatory and space systems
• Collaborate with multidisciplinary teams across software, hardware, optical, and systems engineering
• Implement and enhance DevOps practices, including CI/CD pipelines and system automation
• Perform troubleshooting, debugging, and root-cause analysis of complex software and system issues
• Contribute to distributed processing and real-time systems
• Develop and enhance visualisation tools and user interfaces for operational use
• Ensure software meets the requirements of safety-critical systems
• Support continuous improvement of software quality, performance, and engineering standards

Experience

• A least 3 years’ experience
• Strong experience in C++ development on Windows and Linux platforms within complex engineering environments
• Experience with Python or similar programming languages for system development, automation, and data processing
• Proven experience applying software testing methodologies and frameworks, including unit, integration, and system-level testing
• Experience developing and supporting high-availability, mission-critical software systems
• Exposure to distributed processing and real-time systems, particularly in scientific or observatory environments
• Experience with DevOps practices, including CI/CD pipelines, version control, and automated deployment
• Knowledge of safety-critical software and systems automation, including interaction with hardware or bespoke firmware
• Experience contributing to visualisation tools, user interfaces, and data-driven applications (desirable)
• Familiarity with space systems, astronomical observatories, or laser-based platforms (desirable)
