We are looking for talented Senior Cybersecurity R\&D Engineer who can bridge the worlds of AI and information‑security. The ideal candidate will have relevant R\&D experience in either or both 1\) applying state‑of‑the‑art **AI techniques to strengthen cyber‑defense** (e.g. Deep Learning\-based intrusion detection) and/or 2\) in **securing AI systems themselves** (adversarial robustness, LLM guardrails, model privacy, data‑exfiltration detection, etc.). This role will lead cutting‑edge research projects, translate findings into production‑grade solutions, and mentor a growing team of security researchers. **Key Responsibilities:** * Conceive, design, and execute advanced R\&D initiatives that fuse AI/ML with cybersecurity, including but not limited to: adversarial attack/defense, LLM prompt guardrails, privacy preserving inference, and zero trust micro service security. * Work closely with cross\-functional teams, including software developers, network engineers, data scientists or AI engineers, to integrate research insights into practical applications. * Contribute to multiple projects simultaneously, ensuring timely delivery and achievement of project goals. * Provide guidance and mentorship to junior researchers and team members, fostering their professional growth and development. **Qualifications:** * Master's degree in Computer Science, Software Engineering, Electrical Engineering, Applied Mathematics or a closely related discipline. * A PhD in relevant field will be highly valued. **Experience:** * Minimum of 3\-5 years of relevant experience in academia or industry. * Proven track record of successfully leading or contributing to R\&D activities. **Skills:** * Proficient in Python (with TensorFlow, PyTorch, JAX), C/C\+\+ or Rust for security tooling. * Experience with Docker, Kubernetes, and CI/CD pipelines for ML model deployment. * Familiarity with network protocols, cryptographic primitives, secure coding practices, and threat modeling frameworks (e.g. STRIDE). * Understanding of compliance standards (e.g. ISO 27001, NIST CSF, GDPR, CCPA) as they relate to AI systems. * Proefficiency in statistical analysis, hypothesis testing, and rigorous reproducibility practices. * Ability to design controlled adversarial experiments, evaluate model robustness, and conduct systematic security assessments. * Strong interpersonal skills to work effectively within a multidisciplinary team environment. * Innovative and critical thinking abilities to address research and technical challenges in modern Telecommunications systems, including the integration of AI\-enabled solutions. * Ability to design controlled adversarial experiments, evaluate model robustness, and conduct systematic security assessments. * Very good written and verbal communication; ability to translate complex security concepts for non technical stakeholders. * Strong teamwork mindset, comfortable leading interdisciplinary groups and mentoring early career researchers. **Application:** Send your application to \ Poderá encontrar o anúncio original publicado em: https://www.itjobs.pt/oferta/506671/senior\-cybersecurity\-r\-d\-engineer
