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 verticalsData 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 aCybersecurity 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.

• 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 preference for scripting and automating your way out of repetitive tasks. You understand that in a cybersecurity environment platform downtime directly impacts enterprise defense so you are dedicated to defending system stability and uptime. Most importantly you understand that supporting a global security mission means following strict rules around access governance and compliance.

• 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)

• Bachelors degree in a relevant discipline such as Computer Science Cybersecurity Information Security or a related field or equivalent practical experience

• Metrics and Observability: Practical experience building and managing monitoring alerting and logging platforms (e.g. Datadog Prometheus Grafana) to track SLIs/SLOs and troubleshoot performance bottlenecks proactively. You dont wait for users to report an outage you catch issues before they surface.

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

• Platform and Cloud Security Fundamentals: Understanding of platform network application and cloud security fundamentals tools and concepts with the ability to apply automation to ensure desired and consistent security configurations are maintained.

• Compliance and Governance Awareness: Familiarity with data residency isolation and regulatory compliance requirements particularly within a European or EU Sovereign context. You understand that supporting a global security mission means adhering to strict rules around access and governance.

• 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
