Q-CTRL faces a dynamic security landscape shaped by industry, customer and compliance requirements, which is now evolving in a post-Mythos era. The Infrastructure team is expanding to bring on a Senior Security Engineer with a focus on designing, implementing, and maintaining systems to fulfil the Q-CTRL Security Objectives, as well as identifying practical ways to leverage AI within our security engineering practices.

- Previous experience in DevSecOps or DevOps with a dedicated security engineering focus.
- Cloud networking and Kubernetes experience, including knowledge of ZTNA and secure network access.
- Experience with firewall technologies, at both the cloud (e.g., AWS, GCP, Azure) and application levels.
- Experience working with SIEM/SOC tooling such as Splunk or Microsoft Sentinel to identify and triage security alerts.
It would be fantastic if you have these skills/experience but not essential:
- xperience maintaining a vulnerability management system, including running threat modelling sessions and maintaining risk registers.
- Experience with Kubernetes runtime security tooling such as Falco or Sysdig.
- Relevant security or Kubernetes certifications, such as Certified Kubernetes Security Specialist (CKS) or Offensive Security Certified Professional (OSCP).
- Experience with AI-assisted security scanning or penetration testing.
- Red teaming experience, particularly within cloud or AWS environments.
- Experience using open-source observability tooling such as OpenTelemetry and Grafana to set up security alerting and monitoring.
- Hands-on experience hardening Linux operating systems and container images.
