Critical Infrastructure Security Jobs (NOW HIRING)

Security Monitoring, Alerting & SIEM Ownership: Working with the Information Security team, design, implement, and maintain alerting rules, dashboards, and runbooks across our SIEM and logging platforms, with a focus on identity, access, and SaaS security signals. Continuously tune alerts to reduce noise, improve fidelity, and align with error budgets and SLOs for critical security and identity services.

Endpoint Defense In Depth: Architect and implement our multilayer endpoint defence systems (e.g. Crowdstrike, Cyberark, Cloudflare, secure browser policies), balancing risk against usability in coordination with the Information Security team.

Identity Platform & Access Automation: Build and maintain automation for our identity platforms (e.g., SSO, SCIM provisioning, groupbased access policies, lifecycle workflows) in partnership with Information Security. Implement guardrails and policyascode for identity, ensuring changes are reviewed, tested, and auditable before reaching production.

Infrastructure as Code & Security Controls as Code: Use IaC and configuration management (e.g., Terraform, Ansible, or similar) plus scripting languages (e.g., Python, Go) to deploy and manage security tooling, integrations, and policies. Treat security controls (e.g., logging, scanning, hardening, secret management) as software artifacts that can be versioned, tested, and rolled back safely.

Observability & Integration with Core IT Operations: Ensure that logging, metrics, and tracing for securityrelevant systems (IdP, VPN, endpoint protection, critical SaaS) are robust, accurate, and integrated into our observability stack. Integrate security events and automations with ITSM and incident management workflows, enabling fast routing, triage, and resolution.

Incident Response & PostIncident Engineering: Participate in the oncall rotation for relevant security and identity services. Lead or contribute to postincident reviews, turning root causes into preventative engineering changes (new alerts, automations, guardrails, or documentation) that reduce MTTR and recurrence.

AIEnabled Security Operations: Use AI tooling (e.g., LLMbased assistants, automation platforms) to accelerate alert triage, enrichment, and investigation, while keeping humans in control of decisions. Identify opportunities to embed AI in security and IT operations workflows (e.g., threat intelligence and alert correlation) and help implement these safely and effectively.

Security Engineering & Operations Background: Significant handson experience (4-7 years) in security engineering, security operations, or closely related roles in modern, fastpaced environments (e.g., SaaS, enterprise IT, cloudnative infrastructure).

Identity & Access Management Expertise: Practical experience operating IdPs and IAM systems at scale (e.g., Okta, Azure AD, or similar), including SSO, MFA, lifecycle management, and leastprivilege policies. Experience designing and implementing automated provisioning and deprovisioning (e.g., SCIM, HRIS integrations, groupbased and rolebased access models).

SIEM, Logging & Observability: Proven experience with SIEM and observability platforms (e.g., ELK/EFK, Splunk, Datadog, or similar), including writing and tuning detection rules, building dashboards, and working with largescale log ingestion. Comfort working with SLIs/SLOs and error budgets for critical services, and using these to guide priorities for hardening and automation.

Automation & Infrastructure as Code: Strong experience with IaC and configuration management tools (e.g., Terraform, CloudFormation, Ansible, or similar) and with scripting/programming languages (e.g., Python, Go, or equivalent) to automate security and operational tasks. Track record of converting manual, repetitive operational work into reliable automation and selfservice capabilities.

Security Controls Implementation: Experience implementing and operating security controls as code: vulnerability scanning, configuration baselines, secret management (e.g., HashiCorp Vault), key rotation, and certificate management.

Incident Management & CrossFunctional Collaboration: Demonstrated experience participating in or leading incident response, root cause analysis, and postincident followthrough in partnership with IT Ops, Security, and Engineering. Strong communication skills in English, able to explain complex security and operational topics to both technical and nontechnical audiences.

AI Fluency: Comfortable using modern AI tooling (e.g., LLMbased assistants, automation frameworks) as part of daily work for analysis, content generation, and workflow automation. Ability to reason about where AI is and isn't appropriate in security and operations, balancing speed with risk and control.
