Data Platform Engineer - Cybersecurity

We are a newly formed, forward-looking Cybersecurity Data Engineering & Platform Team driving the future of our enterprise defense strategy. Our mission is to build a next-generation, centralized data lakehouse that unifies all security telemetry into a single, high-performance ecosystem. The Data Platform Vertical includes foundational infrastructure, security architecture, and AI enablement. As a member of this vertical, you will join the infrastructure backbone of this global organization. As a Cybersecurity Data Platform Engineer, you will bring a software engineering approach to system administration and operations. You will defend the reliability of the platform, scale it efficiently, and aggressively automate away manual toil. Based in the Dublin hub, you will serve as the dedicated platform operator for the EU Sovereign Region, ensuring daily operations, automation, and administration strictly adhere to European data residency, isolation, and compliance regulations.

Responsibilities

Platform Operations & Reliability: Manage the day-to-day administration, configuration, and capacity planning for our modernized cybersecurity data platform to ensure maximum uptime and stability; EU Sovereign Administration: Act as the dedicated, hands-on operator for our EU Sovereign Region, strictly adhering to established data residency and isolation protocols in all deployments and incident responses; Defending Service Levels & Observability: Define and track Service Level Indicators (SLIs) and Objectives (SLOs) for platform health, compute usage, and storage capacity; Toil Reduction & IaC Execution: Treat operations as a software problem. You will utilize, maintain, and write Infrastructure-as-Code (IaC) and automation scripts to eliminate manual operational toil, streamline deployments, and enable auto-scaling; Guardrails & Incident Response: Implement resource quotas and technical guardrails to protect the platform from noisy neighbors. When issues do occur, you will lead troubleshooting efforts and participate in blameless post-mortems to ensure systemic issues are fixed in code

Requirements

4+ years of hands-on experience in cloud infrastructure operations, platform engineering, or reliability engineering; 4+ years of experience administering enterprise Linux environments; 4+ years operating within major cloud platforms (AWS, GCP, or Azure); 2+ years experience with compute, storage, networking, and Identity Access Management (IAM)

Nice to have

Bachelor's degree in a relevant discipline such as Computer Science, Cybersecurity, Information Security, or a related field, or equivalent practical experience; Practical experience building and managing monitoring, alerting, and logging platforms (e.g., Datadog, Prometheus, Grafana) to track SLIs/SLOs and troubleshoot performance bottlenecks proactively; Hands-on experience writing and maintaining scripts (Python, Bash, Go) and working with IaC tools (e.g., Terraform, Ansible, CloudFormation); Understanding of platform, network, application, and cloud security fundamentals, tools, and concepts; Familiarity with data residency, isolation, and regulatory compliance requirements, particularly within a European or EU Sovereign context; Ability to manage multiple projects and priorities while handling operational responsibilities; Excellent written and verbal communication skills, with the ability to build positive relationships with partner teams across global time zones
