Founded in 2003 and headquartered in Singapore, Group-IB is a leading creator of cybersecurity technologies to investigate, prevent, and fight digital crime. Combining cybercrime defence into our DNA, the company builds capabilities to protect businesses, citizens, and support law-enforcement operations. Group-IB is hiring a Senior DevOps Engineer who understands infrastructure beyond abstractions - Linux, networking, and Kubernetes at a deep level. You'll be working on high-load, high-availability infrastructure that supports production systems at scale. The role requires real depth: you understand how systems work under the hood, can debug issues beyond dashboards, and have worked with infrastructure, not just abstractions. Your work will directly impact system reliability, performance under load, and incident response and recovery. This is real infrastructure engineering - not internal tooling or purely cloud-managed environments.
