InfraSec operates on a preventative, enabling model: rather than acting as a manual approval gatekeeper or compliance auditor, we develop automated guardrails and platform capabilities. We integrate security directly into the platform runtime, CI/CD, and Infrastructure-as-Code (IaC) workflows so engineering teams can operate securely at scale without friction.
We are looking to speak to candidates who are based in Dublin for our hybrid working model.
What You’ll Do
- Harden hosts and containerized workloads using Linux security mechanisms (AppArmor, SELinux, seccomp, cgroups) and eBPF-based tooling (Cilium, Tetragon)
- Secure containerized infrastructure across multi-cloud environments via RBAC, network policies, admission controls (Gatekeeper), and runtime threat detection
- Build and manage automated services for Cloud Security Posture Management (CSPM), workload identity, vulnerability management, and access controls across AWS, Azure, and GCP
- Write production-quality code and leverage Infrastructure-as-Code (Terraform) to version, test, and deploy security controls as code
- Build real-time security monitoring, logging, and alerting systems to detect anomalies and track security posture at Atlas scale
- Lead initiatives across their full lifecycle; from threat modeling and architectural design to implementation, rollout, and long-term production reliability
What We’re Looking For
Minimum Qualifications
- 10+ years in SRE, Infrastructure Engineering, or Cloud Security Engineering
- A track record of operating at Staff or Principal scope: defining technical directi
