Full Stack AI Engineer - Security

Build the Future of Intelligent Defense at arrivia

At arrivia, we don’t just facilitate world-class travel; we are redefining the intersection of technology and exploration. As we accelerate our investment in AI and next-gen IT infrastructure, we are looking for a Full Stack AI Engineer - Security to help lead the charge in protecting our global platforms.

This role sits at the intersection of machine learning, cybersecurity, and full-stack engineering. You won't just be monitoring dashboards; you’ll be architecting intelligent defenses that keep our members and data safe from evolving digital threats.

The Opportunity

As a core member of our IT Operations team, you will design, build, and deploy AI-driven systems that detect and neutralize fraud, abuse, and intrusion. You will have the opportunity to apply anomaly detection, graph analysis, and NLP to real-world security challenges, ensuring our "customer-first" culture is backed by reliable, high-performance safety measures.

What You’ll Do

• Design & Architect: Implement AI/ML models to proactively respond to security threats like identity risk, malware, and insider anomalies.
• System Reliability: Build and maintain robust pipelines for data ingestion, feature engineering, and model deployment within production systems.
• Adversarial Research: Stay current on adversarial ML techniques and adapt our defenses to stay ahead of emerging risks.
• Collaborative Impact: Partner with DevSecOps and Platform teams to embed AI protections directly into our core workflows.
• Automate Response: Enhance incident response by providing AI-based insights and automated remediation strategies.

Who You Are

• Skilled in Modern Tech: You have a solid foundation in Python and frameworks like PyTorch, TensorFlow, or scikit-learn. You’re comfortable navigating large-scale data systems (SQL/NoSQL) and MLOps practices.
• Security Experienced: You bring 3–5 years of experience in cybersecurity, fraud detection, or trust & safety, with a deep understanding of threat modeling and secure model design.
• AI Focused: You have 1–2 years of hands-on experience in AI technologies, specifically building systems that operate under strict latency and reliability constraints.
• Analytic Problem-Solver: You can effectively balance the trade-offs between rigorous security, system performance, and a positive user experience.
• Growth Mindset: You enjoy staying up-to-date with new AI frameworks (such as ISO/IEC 42001 or OWASP) and exploring the latest in time-series anomaly detection.
