About the role

  • Conduct security assessments and build a prioritized remediation roadmap across infrastructure and services
  • Harden AWS and Kubernetes environments: IAM, network policies, workload isolation, secrets management
  • Secure AI-specific attack surfaces: prompt injection defenses, PII handling in LLM pipelines, model interaction data leakage
  • Embed automated security into CI/CD: dependency scanning, container image scanning, code analysis, secrets detection
  • Design secure-by-default patterns for service communication, authentication, and data handling
  • Build incident response capabilities: detection, alerting, response workflows, and post-incident review
  • Partner with engineering teams to improve security posture without becoming a bottleneck

Requirements

  • 6-10+ years of professional security engineering experience in production environments
  • Deep hands-on expertise in cloud security (AWS strongly preferred) and container/Kubernetes security
  • Strong application security skills: securing APIs, microservices, auth flows, and data pipelines
  • Experience with automated security tooling in CI/CD (SAST, DAST, dependency scanning, container scanning)
  • Offensive security mindset: ability to think like an attacker, identify non-obvious vulnerabilities, and validate defenses
  • Track record of building or significantly maturing security programs, not just operating existing ones
  • Nice to have AI/LLM security experience (prompt injection, model security, PII in AI pipelines)
  • CTF participation, bug bounty track record, or formal red team experience
  • Offensive security certifications (OSCP, OSWE, CRTP)
  • Incident response and digital forensics
  • SOC2/ISO27001 compliance implementation (not just audit management)
Benefits
  • Compensation: above typical backend band for Greek/EU market
  • Remote: fully remote within EU, or hybrid from Athens
  • Ownership: first dedicated security hire, define security standards from day one
  • AI-native: real security challenges at the intersection of LLMs, enterprise data, and distributed infrastructure
  • Growth: budget for conferences/courses/certifications, path to security lead / head of security
  • Culture: engineering-first, low meetings, high autonomy, async-first
