• You systematically analyze how Yekta IT appears in common LLMs and AI search systems and identify optimization opportunities • You develop strategies and implement measures for LLM optimization • You create structured, technically accurate content on topics such as penetration testing, OT security, KRITIS and the NIS-2 directive • You use specialized GEO-/AEO tools to measure success and derive concrete actions • You investigate the behavior of AI crawlers and optimize the technical infrastructure • You document methodology, results and recommendations for sustainable use by the team

• Own & Evolve Security Standards - Take ownership of security standards across Phorest, ensuring they are practical, up-to-date, and consistently applied. Continuously improve them in line with evolving threats, business needs, and industry best practice. • Protect Our Cloud & Infrastructure - Configure, maintain, and optimise security tooling across our AWS environment. Lead threat monitoring, improve alert quality, and proactively identify gaps in our security coverage. • Drive Risk Reduction - Lead security assessments across infrastructure and applications. Prioritise vulnerabilities based on risk and work closely with teams to ensure effective remediation. Facilitate threat modelling to catch risks early in the development lifecycle. • Embed Security into Engineering (Shift-Left) - Partner with engineering teams to integrate security into CI/CD pipelines and development workflows — enabling secure-by-default practices without slowing delivery. • Incident Response & Triage - Lead the triage and analysis of security alerts and incidents. Provide clear guidance on remediation and identify patterns to reduce recurring risks. • Be a Trusted Security Partner - Act as a go-to security point of contact across the business. Support teams in making secure decisions, balancing risk with practicality and speed. • Build Security Awareness & Culture - Contribute to internal security education and secure coding initiatives, helping teams understand not just the “what” but the “why” behind security. • Continuously Improve Our Security Posture - Identify opportunities to strengthen our tools, processes, and ways of working — and take ownership of driving those improvements forward.
