• Cloud Security Architecture & Hardening: Own the security posture of Docebo's AWS environments. Define and enforce secure account structures, service control policies (SCPs), guardrails, and baseline configurations across multi-account setups. Evaluate and improve network segmentation, IAM boundaries, and data protection controls. Identify and remediate misconfigurations using CSPM tooling and manual review.
• Infrastructure as Code Security: Partner with Cloud Infrastructure to integrate security controls into IaC workflows. Define guardrails to catch insecure configurations before deployment. Own security scanning in CI/CD pipelines and promote a shift-left approach to cloud security across engineering teams.
• Incident Response & On-Call: Participate in the on-call rotation for security incidents, including triage, containment, and escalation for after-hours events. Lead investigation and root cause analysis for cloud security incidents with clear written post-mortems. Leverage automation and AI tooling to reduce mean time to detect and respond.
• Cloud Detection & Threat Monitoring: Build and maintain detection coverage for cloud-native threats (privilege escalation, unusual API activity, lateral movement, data exfiltration, and more). Leverage CloudTrail, GuardDuty, and SIEM integrations to maintain visibility across the AWS estate. Align detection logic with MITRE ATT&CK for Cloud.
• Vulnerability & Configuration Management: Own vulnerability management for cloud workloads — prioritizing findings from cloud configuration assessments, and runtime protection tools. Drive remediation with Engineering and Infrastructure teams, and build automated enforcement where manual review doesn't scale.
• Identity & Access Management: Define and enforce least-privilege principles across AWS IAM, service accounts, and federated identity. Review and improve IAM policies, permission boundaries, cross-account roles, and access patterns. Reduce standing access and enforce JIT access where appropriate.
• Development of Security Best Practices: Develop and document best practices, policies, and procedures for cloud security. Provide guidance and training to engineering and infrastructure teams to promote a security-aware culture.
• Vendor relationships: Maintain relationships with security vendors for technical issues, ensure smooth operations of security tools and services, and escalate problems or incidents to vendors when required.

• 5+ years of relevant work experience in cybersecurity, with a strong focus on cloud security in production AWS environments.
• Deep hands-on experience with AWS security services: IAM, SCPs, CloudTrail, GuardDuty, Config, KMS, VPC security, and more.
• Good knowledge of Kubernetes security — including RBAC, pod security standards, network policies, admission controllers, and secrets management.
• Experience with cloud security posture management (CSPM) and cloud workload protection (CWPP/CNAPP) tools.
• Experience securing IaC pipelines (Terraform, CloudFormation) and integrating security scanning into CI/CD workflows.
• Good experience with container and image security — scanning, runtime protection, supply chain risk.
• Experience with SIEM and detection engineering — building and tuning cloud-native detection rules, threat hunting across CloudTrail and application logs.
• Familiarity with automation platforms and AI-driven security tools to streamline detection, enrichment, and response.
• Experience with Infrastructure as Code (IaC) and scripting (Python, Bash, or similar) to develop custom security tooling and automate workflows.
• Strong IAM fundamentals: least privilege, cross-account roles, permission boundaries, federated identity, and privileged access management.
• Comfortable working across Azure/GCP in addition to AWS — multi-cloud exposure is a plus.
• In-depth knowledge of information security principles and cybersecurity frameworks relevant to cloud environments: MITRE ATT&CK for Cloud, CIS Benchmarks, AWS Well-Architected Security Pillar, NIST CSF, SOC 2, ISO 27001.
• Willingness and ability to participate in an on-call rotation, including after-hours response.
• Ability to produce clear, comprehensive, and well-structured documentation (e.g. incident reports, architecture reviews, runbooks, and security standards) and to communicate complex technical issues effectively to non-technical stakeholders.
