With our team of 83,000 people across 4,000 locations, our unmatched scale, connected portfolio, and deep local relationships make us the partner of choice for transportation, water, and reindustrialization projects, shaping communities for a better tomorrow. CRH (NYSE: CRH) is a member of the S&P 500 Index. For more information, visit www.crh.com.

Without you noticing our products, we are everywhere you live, work, and relax.

Our project portfolio includes some of the most sustainable and cutting-edge building projects around the world. Think of the asphalt on the Silverstone Grand Prix Circuit, the Paris Metro Rail project, but also the Louis Vuitton Museum in Paris, parts of the Burj Khalifa, and the Kennedy Space Centre.

Role Overview

We are seeking an experienced Senior Cybersecurity Incident Response Analyst to act as a key escalation point from the Security Operations Centers (SOC). In this role, you will lead the investigation, containment, and resolution of complex, high-impact security incidents, working closely with incident response leadership and cross-functional teams. You will provide clear, data-driven insights and communications to support timely decision-making.

Outside of incident response, you will strengthen security posture through threat hunting and detection engineering, leveraging lessons learned and threat intelligence to enhance SOC capabilities. This is a hands-on role suited to a technically strong professional with sound judgment and a collaborative approach in a global environment.

This role operates within a global function and requires flexibility for out-of-hours support. While work-life balance is supported, regular presence in a CRH office is expected, particularly for onboarding, sensitive activities, and team collaboration.

Key Responsibilities

Incident Response:

Work with a team of responders, the incident response manager and cybersecurity leadership as needed and collaborate with infrastructure, IT, vulnerability, threat intelligence, and application security teams
Serve as a point of contact to respond and investigate suspected and confirmed cybersecurity incidents, which may include off-hours or on a scheduled rotation
Examine incidents that may be related to ransomware, host compromise, account compromise, phishing, anomalous user behavior, third parties and data leakage
Collect and analyze information from multiple event sources and internal and external sources
Document and communicate incident details from initial investigation through closure and post-mortem including to validate, document, prioritize, recommend and complete root cause analysis
Support process improvement of monitoring and response metrics including mean time to respond, key performance indicators (KPIs), and service-level objectives (SLOs) for security events and incidents
Liaise with security operations to improve monitoring and response workflows
Perform incident analysis and trend reporting for host, network, identity, and third-party events
Regularly participate in IR tabletop exercises designed to test, identify gaps, improve skills, enhance communication, and engage with key stakeholders
Refine and maintain playbooks, policies, procedures, and guidelines to ensure they align with industry best practices
Remain current with emerging threats and share knowledge with colleagues to improve incident response

Threat Hunting:

Identify misconfigurations, vulnerabilities, missing, or improperly applied security controls
Conduct research of current and emerging threats facing the business and industry sector to identify associated indicators of compromise, tactics, techniques, and procedures
Review events to support threat hunting based on anomalies and possible true-positive incidents
Review reports from tabletops, vulnerability, and penetration testing assessments to proactively identify weaknesses
Actively hunt for exposures and identify incidents warranting action to disrupt and remediate threats
Actively participate in threat hunting exercises to hone and strengthen skills across the team

Detection Engineering Activities:

Build or modify scripts for detection engineering and threat hunting
Take observables (e.g., IOCs, TTPs, etc.) and use these to create searches or detections for signs of observables on internal systems
Proactively identify and define the lifetime value of observables / detections
Test detections to identify and tune out false positives
Provide detection logic to Security Engineering team for deployment to production
Support Security Operations and Engineering efforts to refine detection logic as required
Be familiar with prompting, AI agents, copilots and MCP solutions to analyze events across data sources
Perform other duties as assigned

Education & Experience

5–8 years’ experience in cybersecurity, with a focus on incident response or SOC operations
Proven experience leading major incident investigations and response
Strong background in threat hunting and detection engineering
Hands-on expertise with SIEM, EDR, IDS/IPS, and forensic tools
Experience across cloud environments (AWS/Azure) and identity systems (AD/Azure AD)
Relevant certifications (e.g., GCIH, GCFA, CISSP) desirable
