**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**
**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 workflows to significantly reduce manual threat investigation cycles.
- **Collaborative Impact**: Partner with DevSecOps and Platform teams to build MLOps pipelines and embed AI-driven protections directly into containerized environments (Docker/Kubernetes).




**Who You Are**
- **Skilled in Modern Tech**: You have a solid foundation in Python, SQL, and ML frameworks like PyTorch, TensorFlow, or scikit-learn.
- **Experienced with Distributed Systems**: You are comfortable working with large-scale data systems, stream processing, and containerized deployments using AWS, Docker, and Kubernetes.
- **Security Focused**: You bring a strong background in cybersecurity, fraud detection, trust & safety, or threat intelligence, alongside a deep understanding of secure system design and OWASP principles.
- **API & Backend Specialist**: You have proven experience designing robust, scalable microservices capable of handling strict latency and reliability constraints.
- **Analytical Problem-Solver**: You can effectively balance the trade-offs between rigorous security, high system performance, and a positive user experience.
- **Growth Mindset**: You enjoy staying up-to-date with secure AI frameworks (such as ISO/IEC 42001 or OWASP) and exploring advanced methods like time-series anomaly detection and graph analysis.
**Qualifications**
- Bachelor's degree in Computer Science, Information Systems, Engineering, or a related field (Master's preferred).
- 5+ years of software engineering experience, with a heavy focus on backend architecture, API design, and distributed systems.
- 3+ years of experience in cybersecurity, fraud detection, trust & safety, or abuse prevention.
- 2+ years of hands-on experience building and deploying machine learning models in a production environment.
- High proficiency in English with strong collaboration and communication skills.
- Must be based in Mexico and available to work remotely.
