Are you a seasoned Security Engineer with a passion for protecting infrastructure at scale? A rapidly growing technology-driven organisation is looking for a Senior Security Engineer to play a pivotal role in safeguarding critical systems, networks, and data in a fast-paced and innovation-led environment.
You'll join a high-performing Platform Engineering team, working alongside cloud specialists, DevOps professionals, and software engineers to build secure, scalable platforms. This is more than a pure security role - it's an opportunity to be hands-on in architecture, engineering, and compliance, while leading the charge on modern, cloud-first security strategy.
Responsibilties:
Designing and implementing robust security policies, controls, and infrastructure protection strategies.
Leading vulnerability management efforts, penetration testing, and remediation plans.
Monitoring and investigating security events, managing incident response processes end-to-end.
Ensuring compliance with security standards such as ISO 27001 and supporting audits and certifications.
Collaborating across teams to embed security into the core of platform and product development.
Delivering internal security awareness initiatives to strengthen company-wide security culture.
Evaluating and integrating new security tooling across a modern tech stack.
Supporting business continuity and disaster recovery planning from a security lens.
You'll Bring:
Strong background as a Security Engineer or similar role within fast-paced technical environments (ideally with experience in regulated or high-trust industries).
Hands-on expertise in cloud security (preferably AWS), including securing hybrid and multi-region architectures.
Practical knowledge of security tooling: IDS/IPS, SIEM, vulnerability scanners, encryption, SAST/DAST tools, OWASP ZAP, etc.
Strong understanding of network security protocols and best practices.
Scripting and automation experience (eg Python).
Proven experience with incident response and threat mitigation.
Familiarity with security compliance frameworks (ISO 27001, SOC 2, etc.).
Security certifications (eg Security+, CISSP, or equivalent) are a plus.
You'll Thrive If You Are:
Comfortable taking ownership and working autonomously in a high-accountability environment.
Eager to learn and keep up with the latest in security practices and technologies.
A confident communicator who can bridge the gap between technical and non-technical stakeholders.
Passionate about secure-by-design principles and building secure systems from the ground up.
