Build and maintain critical infrastructure components that support high availability, resilience, and secure production operations. Develop and optimize infrastructure-as-code practices and automated deployment workflows to reduce manual work and improve consistency. Contribute to infrastructure strategy and technical decision-making, evaluating new tools and technologies based on business needs and technical merit. Work across technical and non-technical teams to align infrastructure decisions with broader organizational objectives. Participate in a weekly on-call rotation, acting as a key escalation point for production incidents affecting 24/7 services. Lead incident investigation and root cause analysis, implementing lasting corrective and preventative measures. Identify opportunities to improve monitoring, alerting, operational visibility, and incident response. Leverage AI tools to support incident triage, infrastructure-as-code generation, runbook development, and other engineering workflows. Promote secure-by-design infrastructure practices and contribute to compliance readiness and ongoing security improvements. Requirements: The ideal candidate is an experienced DevOps, Site Reliability Engineering, or cloud infrastructure professional with strong architectural capabilities and a hands-on approach to production operations.

Practical experience with AWS services, including IAM, VPC, EC2, Elastic Load Balancing (ELB), RDS, S3, Lambda, API Gateway, Secrets Manager, KMS, CloudWatch, and CloudTrail. Production experience with Terraform or Terragrunt for infrastructure as code. Experience with configuration management tools such as Chef or Puppet. Familiarity with GitHub, GitHub Actions, Jenkins, JFrog Artifactory, and GitOps workflows. Experience using monitoring and observability tools such as Datadog, Prometheus, or Grafana. Ability to read and work with code written in Java, Ruby, Bash or Zsh, HCL, Python, and JavaScript. Strong troubleshooting and problem-solving skills, particularly when diagnosing production incidents and implementing durable solutions. Ability to collaborate effectively with software engineers and stakeholders across different functions. Strong ownership, sound technical judgment, and a proactive approach to infrastructure reliability and security. Willingness to participate in a weekly on-call rotation supporting production systems operating 24/7. Preferred qualifications: Experience with container orchestration platforms such as Amazon ECS or Kubernetes-based Amazon EKS. Familiarity with SOC 2 requirements and secure-by-default infrastructure practices. Knowledge of Layer 7 (L7) load balancing. Interest in applying AI and automation to improve infrastructure engineering and operational efficiency. Benefits: Fully remote work: Remote working arrangement, with the source listing Croatia, Spain, and the United Kingdom as eligible locations. Technical ownership: Opportunity to influence infrastructure architecture, tooling decisions, and engineering practices. AI-enabled workflows: Access to AI tools and encouragement to explore new ways to improve engineering productivity. Collaborative environment: Close partnership with developers and cross-functional teams, with an emphasis on open discussion and shared problem-solving. Professional impact: Responsibility for critical infrastructure supporting around-the-clock services.
