Operations Engineer

About the role

KAYAK, part of Booking Holdings, is a travel search engine and is looking for an Operations Engineer in Kaunas. The Operations team keeps the platform reliable, available and ready for change, and this role works with a cross-functional team to maintain the infrastructure and production systems that millions of travelers use every day. It involves incident response, platform reliability and continuous improvement of tools and processes.

Key responsibilities

• Maintain infrastructure and platform reliability across production and non-production environments, including compute, storage, networking and container orchestration.
• Take part in on-call rotations, triage incidents, follow runbooks and escalate appropriately.
• Contribute to post-incident reviews and identify recurring issues.
• Apply configuration management and infrastructure-as-code (Puppet, Terraform, Ansible) to keep environments consistent, recoverable and auditable.
• Support the lifecycle of platform services, including provisioning, patching, upgrades and decommissioning, across hypervisor, Kubernetes and VM environments.
• Monitor system health with observability tooling, investigate alerts and improve alert quality.
• Collaborate with engineering, security, database and release engineering teams on production changes, maintenance windows and cross-team issues.
• Write operational documentation such as runbooks, how-to guides and post-incident summaries.
• Contribute to capacity and performance work, and explore AI-assisted tooling that reduces toil.

Required profile

• 3+ years of experience in infrastructure, platform or operations engineering, or equivalent practical experience.
• Hands-on Linux experience in production, with networking fundamentals (DNS, load balancing, firewalls) and compute/storage concepts.
• Experience with container orchestration (Kubernetes or equivalent) and on-call or incident response.
• Clear written and verbal English, able to write technical documentation and work with distributed teams.
• A collaborative, team-first approach; a technical degree is welcome but not required.

• Configuration management or IaC: Puppet, Terraform or Ansible.
• Container orchestration: Kubernetes or equivalent.
• Observability: Prometheus, Grafana or similar.
