**Location: Banja Luka, Bosnia and Herzegovina (primary) or Belgrade, SerbiaWhat You’ll Do:
As a Senior Security Engineer, you will own the security architecture and enforcement across our infrastructure. Our infrastructure relies heavily on a Linux ecosystem, and as we scale our cloud footprint and AI initiatives, this layer is becoming increasingly security-sensitive. You will be embedded directly with the teams operating these systems, bridging the gap between high engineering velocity and secure-by-design architecture. Your core mandate is to protect production, harden our Linux environments, establish AI guardrails, and build secure access patterns without creating process overhead. This role will report to the Sr Director, Infrastructure and Networking and will be a hybrid role based out of Banja Luka, Bosnia.
- Linux Hardening & Threat Detection: Secure our underlying Linux infrastructure and container runtimes. Deploy, tune, and manage our SIEM for continuous threat detection, file integrity monitoring, and host-based intrusion detection (HIDS) across our fleet.
- Identity & Access Control: Design and enforce secure access patterns. Ruthlessly eliminate shared accounts, long-lived credentials, and overly broad permissions across the organization.
- Cloud & Infrastructure Governance: Own the security posture across our cloud environments. Implement secure infrastructure-as-code practices using Terraform and Terraform workflow.
- AI & Agentic System Security: Establish infrastructure-level guardrails for AI tooling and agentic systems, including tool permission boundaries, secrets exposure prevention, data egress controls, audit logging, approval workflows for sensitive actions, and controls against prompt-injection-driven misuse of internal systems.
- Secure CI/CD & Supply Chain: Protect our production deployment paths against supply-chain attacks.
- Policy-as-Code & Preventive Guardrails: Build and maintain automated security controls into Terraform, Terraform Workflow, Git repository, and CI/CD workflows.
- Vulnerability Management: Drive faster CVE response times and vulnerability closures across our infrastructure. Reduce the ad hoc security burden currently spread across the engineering team.
