Job description

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
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
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
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- 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
Bachelor’s degree in a relevant discipline such as Computer Science, Cybersecurity, Information Security, or a related field, or equivalent practical experience
2+ years experience with compute, storage, networking, and Identity Access Management (IAM)
Ability to manage multiple projects and priorities while handling operational responsibilities
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 don’t wait for users to report an outage — you catch issues before they surface
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
4+ years operating within major cloud platforms (AWS, GCP, or Azure),
Excellent written and verbal communication skills, with the ability to build positive relationships with partner teams across global time zones
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
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
4+ years of experience administering enterprise Linux environments
4+ years of hands-on experience in data engineering, cloud infrastructure operations, platform engineering, or site reliability engineering (SRE)
2+ years of experience building, maintaining, or operating data pipelines (e.g., ETL/ELT, streaming, or batch processing)
Bonus: Hands-on experience with Splunk (administration, search, or troubleshooting) — not required, but valuable given our current environment; we’re happy to train the right candidate
Bonus: Experience with data reliability engineering — data quality monitoring, pipeline SLAs/SLOs, or data observability tooling
