Our cutting-edge technology fuels significant growth in climate, sustainability, and defence & intelligence/national security markets, with HotSat-1 launched in 2023 and HotSat-2 and HotSat-3 planned for 2026.

At SatVu, we value Cybersecurity as the first—and last—line of defence, safeguarding our sensitive data from cyberattacks. We're seeking an experienced and vigilant Cyber Security Engineer who can take full ownership of securing our entire digital estate, ensuring best practices are implemented across the board. This is a unique opportunity to join a dynamic, high-growth organisation and directly influence SatVu's future success.

The Role

As our Cyber Security Engineer, you will be at the forefront of protecting SatVu's critical data and systems. You will proactively monitor our digital infrastructure, identify and mitigate threats such as malware and ransomware, and implement robust solutions to address vulnerabilities, with a focus on prevention and swift remediation.

You will have a deep understanding of cybersecurity standards, certifications, and the evolving tactics of cybercriminal groups, along with an unwavering determination to keep them out.  

This position sits within our dedicated DevSecOps team and offers the opportunity for professional growth and impact within a dynamic, high-growth organisation where you will directly influence SatVu's future success.
