About the Team

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. Operating across two specialized verticals—Data Logistics (ingestion, enrichment, and semantic layers) and Data Platform (foundational infrastructure, security architecture, and AI enablement)—we are designing a scalable, cloud-native foundation from the ground up. By combining cutting-edge data architecture with advanced analytics, we empower our threat hunters, data scientists, and incident responders with the real-time, trusted intelligence needed to protect the enterprise at scale.

The Data Platform Vertical
As a member of the Data Platform vertical, you are joining the infrastructure backbone of this global organization. Operating across distributed hubs in Dublin, US, and New Zealand, we are the team responsible for ensuring the underlying architecture is highly performant, automated, and governed by strict enterprise standards. We are actively moving away from our SIEM-based data platform toward a modern, Infrastructure-as-Code (IaC) model. Crucially, our Dublin team serves as the anchor for our EU Sovereign operations, ensuring our modernized platform meets the strict data residency, isolation, and compliance mandates required to protect our European region.

About the Role

As a Cybersecurity Data Platform Engineer, you will bring a software engineering approach to system administration and operations. While our Principal engineers architect the overarching system, your mission is to defend its reliability, scale it efficiently, and aggressively automate away manual toil. We are actively transitioning away from a legacy, SIEM-centric environment that suffers from severe resource exhaustion, and we need a dedicated platform engineer to ensure our new infrastructure remains highly available, performant, and resilient.

Crucially, based in our Dublin hub, you will serve as the dedicated platform operator for our EU Sovereign Region. You will ensure that the daily operations, automation, and administration of the platform strictly adhere to European data residency, isolation, and compliance regulations.

In this role, you will be on the front lines of platform health, defining reliability metrics, troubleshooting complex bottlenecks, and ensuring our Data Engineering and Incident Response teams always have a rock-solid foundation to execute their missions.

What You Will Drive

• 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. You will actively monitor these metrics to proactively troubleshoot bottlenecks before they impact users.

• 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.

About You

You are an engineer who treats operations as a software problem. You have a deep intolerance for manual toil, preferring to script and automate your way out of repetitive tasks. You understand that in a cybersecurity environment, platform downtime directly degrades our enterprise defense, so you rigorously defend system stability and uptime. Most importantly, you understand that supporting a global security mission means adhering to strict rules around access, governance, and compliance.

• You Build for Reliability (Experience & Education): You bring 4+ years of hands-on experience in cloud infrastructure operations, platform engineering, or reliability engineering, backed by a Bachelor’s degree (or equivalent practical experience). You excel at O&M, taking pride in keeping critical infrastructure highly available and performant.

• You are a Cloud & Systems Expert: You bring proven, hands-on experience administering enterprise Linux environments and operating within major cloud platforms (AWS, GCP, or Azure). You deeply understand the foundational elements of compute, storage, networking, and Identity Access Management (IAM).

• You are Driven by Metrics & Observability: You don't wait for users to report an outage. You have practical experience building and managing systemic monitoring, alerting, and logging platforms (e.g., Datadog, Prometheus, Grafana) to track SLIs/SLOs and troubleshoot performance bottlenecks proactively.

• You Eradicate Toil (Scripting & IaC): You bring hands-on experience writing and maintaining scripts (Python, Bash, Go) and working with Infrastructure-as-Code tools (e.g., Terraform, Ansible, CloudFormation). You know how to safely modify and deploy automation runbooks to eliminate manual work and streamline routine operations.

Our Approach to Flexible Work
 

With Flex Work, we’re combining the best of both worlds: in-person time and remote. Our approach enables our teams to deepen connections, maintain a strong community, and do their best work. We know that flexibility can take shape in many ways, so rather than a number of required days in-office each week, we simply spend at least half (50%) of our time each quarter in the office or in the field with our customers, prospects, and partners (depending on role). This means you'll have the freedom to create a flexible schedule that caters to your business, team, and personal needs, while being intentional to make the most of time spent together. Those in our remote "home office" roles also have the opportunity to come together in our offices for important moments that matter.

Pursuant to applicable Fair Chance law, Workday will consider for employment qualified applicants with arrest and conviction records.
