Founded in 2003 and headquartered in Singapore , Group-IB is a leading creator of cybersecurity technologies to investigate, prevent, and fight digital crime.

Combating cybercrime is in the company’s DNA, shaping its technological capabilities to defend 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.

This role requires real depth:

• You understand how systems work under the hood
• You can debug issues beyond dashboards
• You’ve 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.

What You’ll Do

• Operate and improve core infrastructure (bare-metal, LXC, VMs, cloud)
• Run and debug Kubernetes clusters in production
• Design fault-tolerant, high-performance systems
• Work deeply with networking (TCP/IP, routing, connectivity issues)
• Build and maintain Infrastructure as Code
• Own incidents end-to-end
• Collaborate with engineers to solve problems — not escalate them

Must-Have

• 4+ years in Linux / DevOps / SRE
• Strong Linux fundamentals (processes, memory, networking, filesystem)
• Solid understanding of networking (TCP/IP, DNS, debugging connectivity)
• Real Kubernetes experience in production — not just usage, but understanding how it works internally
• Experience with:
• Bash scripting
• Configuration management (Ansible / Puppet)
• Monitoring systems (Grafana, Zabbix, etc.)
• Experience with distributed systems / databases

We Value A Lot

• Experience with bare-metal infrastructure
• Kubernetes at node / networking / runtime level
• Debugging real production incidents
• High-load systems experience
• Clear, structured communication
• Strong ownership mindset

If you’re someone who enjoys solving real infrastructure problems — we’d love to hear from you.
