Build the Future of Intelligent Defense at arrivia

At arrivia, we specialize in making brands better through the power of travel,
combining decades of experience with a constant drive for technology innovation.
While our physical offices span the globe, we are looking for a highly skilled,
remote-first engineer to join our team. This specific role is a fully remote
opportunity based within Mexico.

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 by building high-scale, real-time security systems.

The Opportunity

As a core member of our IT Operations team, reporting to the Security Ops Lead,
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 and scale AI/ML models to proactively detect,
prevent, and respond to security threats such as identity risk, fraud,
malware, and insider anomalies.
* System Reliability: Build and maintain robust data ingestion, feature
engineering, and real-time streaming pipelines (e.g., utilizing SQL/NoSQL
databases and messaging frameworks like Kafka) to process high volumes of
security events.
* Deploy Microservices: Integrate AI security models directly into production
workflows by developing high-performance, low-latency APIs and microservices
(using frameworks like FastAPI, Flask, or Django).
* Adversarial Research: Analyze adversarial attacks, threat modeling, and
secure model design to adapt our defenses under evolving threat scenarios.
* Automated Response: Enhance automated incident response, accelerating
remediation wo
