Role Description At arrivia, we specialize in making brands better through the power of travel, combining decades of experience with a constant drive for technology innovation. 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. 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. - Apply anomaly detection, graph analysis, and NLP to real-world security challenges. 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). 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.

Role Description We are seeking a Site Reliability Engineer to join the Platform Security team and take ownership of the systems that keep Elastic's Kubernetes infrastructure secure and compliant at scale, across every environment we operate. - You will be the primary owner of our Kyverno policy enforcement pipeline, governing admission control across Elastic's serverless platform in Commercial and FedRAMP environments. - You will also play a key role in our secrets management infrastructure, helping ensure that short-lived credentials are standard for workloads across the company. - This is a high-leverage, high-trust role where you will make decisions that affect what runs and what doesn't in production. What You Will Be Doing - Own the Kyverno policy enforcement pipeline end-to-end, authoring and maintaining ClusterPolicy definitions, managing progressive rollout across Commercial and GovCloud deployment slices, and handling the manual deployment path for clusters that sit outside the automated pipeline. - Drive the Audit Enforce promotion lifecycle: monitoring policy-reporter data, coordinating with platform teams on workload impact, and rolling enforcement forward through environments in a controlled, documented way. - Contribute to both of our Vault instances by authoring HCL policies, managing Okta identity group wiring in Cloud Vault, and reviewing GitHub permissionset PRs for our infra Vault to ensure workloads get least-privilege, short-lived credentials. - Write the runbooks, enforcement trackers, and operational documentation that keep the team moving safely. Qualifications - 5+ years of platform engineering, security engineering, or infrastructure engineering experience. - Hands-on experience with Kubernetes admission control Kyverno, OPA Gatekeeper, or equivalent including policy authoring, testing in cluster, and production rollout. - Proficiency with Helm and GitOps workflows; comfortable owning multi-repo deployment pipelines. - Production experience with HashiCorp Vault policy authoring (HCL), auth backend configuration (OIDC, AppRole, Kubernetes), or secrets engine management. - Fluency with Terraform; comfortable contributing to large, multi-workspace configurations across multiple environments. - Strong understanding of authentication and authorization primitives OIDC, SAML, short-lived credentials, and least-privilege access patterns. - Comfort reasoning about blast radius: you think carefully about what happens if a policy enforces too early, too broadly, or in the wrong environment. - Clear written communication; you write runbooks and policy documentation that other engineers trust and use. Bonus Points - Familiarity with ArgoCD and progressive deployment patterns. - Background operating Vault in HA/Raft mode at scale, or experience with the kube-vault-controller / vault-realizer pattern for Kubernetes workload credential issuance. - Experience with Buildkite or similar CI/CD systems for infrastructure pipelines. - Contributions to open source tooling in the Kubernetes security or identity space. Compensation Compensation for this role is in the form of base salary. This role does not have a variable compensation component. The typical starting salary range for this role is: - €60.900 — €75.600 EUR Benefits - Competitive pay based on the work you do here and not your previous salary. - Health coverage for you and your family in many locations. - Ability to craft your calendar with flexible locations and schedules for many roles. - Generous number of vacation days each year. - Increase your impact - We match up to $2000 (or local currency equivalent) for financial donations and service. - Up to 40 hours each year to use toward volunteer projects you love. - Embracing parenthood with a minimum of 16 weeks of parental leave.
