Cyber Security Engineer – Space Technology (London, UK)
Technology · London, United Kingdom · Full-time
Our client, a rapidly expanding UK-based space technology company backed by leading institutional investors, is seeking an experienced Cyber Security Engineer to join their London team.
The company develops advanced space-based data capabilities serving climate, sustainability, defence, and national security markets. Following successful in-orbit missions and with additional launches planned, they are scaling both their space and ground infrastructure - making cybersecurity a critical strategic priority.
This is a unique opportunity to take ownership of securing a high-value digital estate within a dynamic, high-growth environment. Cybersecurity is treated as both the first and last line of defence, protecting mission-critical systems and sensitive data from increasingly sophisticated threats.
The Role
As Cyber Security Engineer, you will sit within a dedicated DevSecOps function and play a central role in safeguarding the organisation’s infrastructure, systems, and data.
You will proactively monitor digital infrastructure, identify and mitigate threats (including malware and ransomware), and implement preventative and corrective controls. The role requires deep familiarity with cybersecurity standards, certifications, compliance frameworks, and modern threat actor tactics.
You will report to the Senior DevOps leadership and collaborate closely with DevSecOps, engineering, and wider business teams to continuously improve the organisation’s security posture.
Candidate Profile
We are looking for a proactive and detail-oriented cybersecurity professional who is motivated to make a tangible impact within a mission-driven organisation.
You understand the responsibility involved in securing systems that may be targeted by sophisticated threat actors, and you value strong team collaboration to deliver resilient, world-class security services.
You are a continuous learner who takes initiative, leads where appropriate, and shares knowledge with colleagues. You also recognise that strong cybersecurity extends beyond technical controls to include compliance, documentation, and certification.
