Senior Security Engineer

Nasze wymagania: 5+ years professional experience in cloud security, infrastructure security, or security engineering roles. Strong Azure security services experience: Azure Defender for Cloud, Sentinel, Azure Policy, Key Vault, Private Endpoints, and Entra ID. Kubernetes security expertise: RBAC design, network policies, pod security admission, Workload Identity, and namespace-level security isolation. Container security experience: image scanning tooling (Trivy, Grype or equivalent), supply chain security practices (signing, provenance), and container runtime hardening. IAM and identity depth: managed identities, service principals, OIDC federation, and least-privilege design patterns across cloud and Kubernetes environments. Network security fundamentals: private networking architecture, ingress and egress controls, TLS management, and firewall policy governance. Vulnerability management process experience: from scanning pipeline integration through CVE triage to tracked remediation. Security compliance fundamentals: GDPR principles, audit logging design, data residency requirements, and access control frameworks. Scripting proficiency in Python or bash for security automation and tooling integration. Mile widziane: Cloud security certifications: AZ-500 (Azure Security Engineer), SC-100 (Cybersecurity Architect), or CISSP. Policy-as-code experience: OPA/Gatekeeper or Azure Policy for automated compliance enforcement. SIEM and SOAR experience: Azure Sentinel rule authoring, playbook automation, and incident orchestration. Experience in regulated industries (insurance, finance, healthcare) where security controls must meet external audit and regulatory standards. Exposure to zero-trust architecture patterns and their practical implementation in cloud-native environments. Experience with secrets scanning and pre-commit security tooling integrated into developer workflows. Comfortable in agile, iterative delivery environments; able to ship security improvements incrementally without blocking product teams. Clear communicator across technical and non-technical stakeholders; translates security risk into business terms for Governance and leadership audiences. Proactive learner with pragmatic adoption of AI-assisted developer tools (e.g., GitHub Copilot, Claude Code) to improve security automation and coverage. O projekcie: As a Security Engineer within Advanced Analytics Team you will own the technical security baseline for the platform. Your work is the implementation layer between compliance policy and production infrastructure: you design and operate the controls that make the platform private, hardened, and audit-ready. You will work closely with SREs, Platform Engineers, and the Governance team to ensure every workload on the platform — AI services, Java APIs, and frontend applications — meets Zone 4 security standards and regulatory requirements without becoming a bottleneck for delivery teams.\ Zakres obowiązków: Design and implement cloud security controls across the platform: network policies, private endpoints, Zone 4 compliance configurations, and Azure Policy enforcement. Own workload identity and IAM for AKS: Azure Managed Identity, OIDC Workload Identity federation, RBAC scoping per namespace, and least-privilege access patterns for all platform services. Manage secrets infrastructure: Azure Key Vault integration, secrets rotation policies, Kubernetes secrets standards, and audit logging for secrets access. Implement and maintain container security controls: image scanning pipelines (Trivy), pod security admission, runtime security standards, and supply chain security (image signing and provenance). Operate network security across the platform: private networking design, ingress controls, TLS certificate lifecycle management, and firewall rule governance. Run vulnerability management: integrate scanning into CI/CD pipelines, triage CVEs across base images and platform dependencies, prioritize remediation, and track to closure. Harden baseline configurations for AKS clusters, ACR, and Azure services; maintain documented security baselines and review them against CIS benchmarks and Azure Security Center recommendations. Support audit and compliance requirements: design audit logging coverage, manage log retention, and produce evidence packages for GDPR and regulatory reviews in coordination with the Governance team. Integrate threat detection: configure Azure Defender and Sentinel alerting for security events across the platform; own the security alerting runbook. Translate compliance requirements from the Governance team into concrete technical controls; own the implementation — Governance owns the policy, you own the execution.
