Job Description
Senior DevOps Engineer
Group-IB
• Maintain and optimize core server infrastructure, including bare-metal servers, LXC containers, virtual machines, and cloud environments. • Operate and support core infrastructure services such as Nginx, Puppet, GitLab, Artifactory, Nexus, Harbor, Grafana, etc. • Manage and evolve infrastructure following the Infrastructure as Code (IaC) paradigm. • Handle and resolve incidents related to infrastructure operations. • Collaborate closely with cross-functional teams (network engineers, developers, and other technical stakeholders). • Design and implement high-availability, fault-tolerant, and scalable software solutions. • Monitor service performance and availability using modern observability tools, ensuring system reliability and optimal resource utilization.
Job Requirements
- 4+ years of experience in Linux administration, DevOps, or Site Reliability Engineering (SRE).
- Strong proficiency in automating tasks using Bash or similar scripting languages.
- Solid understanding of networking fundamentals (TCP/IP stack, routing, DNS, etc.).
- Hands-on experience managing bare-metal infrastructure in production environments.
- Experience with configuration management systems such as Ansible or Puppet.
- Experience with distributed databases (Elasticsearch, Cassandra, MongoDB, MySQL, PostgreSQL, etc.).
- Expertise in Kubernetes administration and managing containerized workloads.
- Experience with IaC tools such as FluxCD or ArgoCD.
- Ability to design and implement high-performance, fault-tolerant, and secure infrastructure solutions.
- Experience with monitoring and observability systems — Zabbix, VictoriaMetrics, Loki, Grafana, etc. — including building dashboards and configuring alerting.
Benefits
- Work with real stakes. Group-IB investigates active cybercriminal groups, responds to breaches affecting critical infrastructure, and develops technologies used by law enforcement agencies including INTERPOL, Europol, and Afripol across 60+ countries. We've conducted 1,550+ cybercrime investigations alongside 600+ enterprise customers globally. When you join Group-IB, your work directly disrupts digital crime.
- Grow your way. Choose your own path: deepen your craft as a technical expert, step into leadership, move across to another team, or relocate to one of our Digital Crime Resistance Centers across the Americas, Europe, the Middle East & Africa, Central Asia, and the Asia-Pacific. Your growth is our growth — Group-IB's expansion across 60+ active country operations means real career acceleration.
- We fund professional certifications at company expense — whether you're pursuing CEH, CISSP, OSCP, or specialized certifications in forensics and penetration testing. You don't have to choose between doing the job and advancing your credentials.
- Work alongside industry leaders. Our Unified Risk Platform — Threat Intelligence, Digital Risk Protection, Attack Surface Management, Managed XDR, and more — is recognized by Gartner, Forrester, KuppingerCole, and Datos Insights. Frost & Sullivan named us a 2025 Global Technology Innovation Leader. When you work here, you're building technologies that set the industry standard.
- Real challenges, real expertise. You'll take on complex, real-world problems alongside adversary-centric researchers and incident response experts spread across six continents. We've built 21+ years of proprietary telemetry through 1,500+ joint investigations. No two threats look alike — and neither do the skills you'll develop.
- A team that is genuinely international. Our people come from different countries, speak different languages, and bring different perspectives. What connects us is a shared mission: fighting cybercrime and making the world safer. We care about your wellbeing and happiness as much as your output.

• Own the operational health of computer-vision / AI models and associated services. • Manage reliability and operations, defining SLIs and SLOs for key services. • Ensure observability is trustworthy, improving alert quality and building necessary metrics. • Lead incident response, driving recovery and producing actionable postmortems. • Plan capacity and performance to preempt saturation. • Own business continuity, disaster recovery, and backup strategies. • Engineer software solutions for operational efficiency and reliability. • Govern production change management collaboratively and safely. • Maintain CI/CD pipelines and Terraform configurations for the AWS estate. • Harden security and compliance within the system.
• Own service objectives. Define SLIs and SLOs for the services that matter, manage error budgets, and use them to drive prioritization and change-rate decisions. Make reliability a measured number, not a feeling. • Make observability trustworthy. Own alert quality end-to-end: high signal-to-noise, alarms that reliably catch the incidents they are meant to catch, and the discipline to turn off a misleading alarm until it is fixed properly. Build the dashboards and the custom metrics, exporters, and instrumentation (CloudWatch, OpenTelemetry) needed to see the system clearly. • Lead incident response. Run incidents calmly, drive mean-time-to-recovery down, and produce blameless postmortems with action items that actually get closed. Improve and own the on-call rotation and its health. • Plan capacity and performance. Forecast and right-size compute (especially GPU), Kafka/MSK throughput and partitioning, RDS/TimescaleDB load, and Redis. Catch saturation before customers do. • Own business continuity and disaster recovery. Backups, replication, failover, and recovery for RDS, MSK, Redis, and the edge fleet. Define RPO/RTO and prove them with regular, tested game days, not assumptions. • Keep the edge fleet healthy. Remote diagnosis and recovery over AWS IoT, container auto-update over systemd timers, and the ongoing CentOS 7 migration to the containerized media stack (Ubuntu 22.04). • Engineer away toil. Write real software (Python, Golang, Bash) to automate operational work, self-heal common failures, and make reliability repeatable instead of heroic. • Govern production change safely. Enforce collaborative, reviewed change management; protect the system from risky, unilateral changes (topology, instance-count, scaling, and config).
