What will you do?

As a Senior Platform Engineer you will design, build, and evolve Rebtel's cloud platform and developer infrastructure. You'll play a key role in ensuring our services are reliable, scalable, and secure while enabling engineering teams to deliver faster through modern DevOps practices. Your daily work will span cloud infrastructure, Kubernetes, CI/CD, observability, platform modernization, and close collaboration with engineering teams across the company.

Areas of ownership

• Design, build, and maintain our cloud infrastructure across Azure and GCP using Terraform, including networking, IAM, AKS clusters, node pools, autoscaling, and the foundational components that support our services.
• Build and improve our CI/CD platform using GitHub Actions and Azure DevOps. Create reusable workflows and automate Docker image builds and deployments.
• Streamline software delivery by driving GitOps-based deployments across development, staging, and production environments.
• Own and evolve our monitoring and observability ecosystem, including Elastic/Kibana, Datadog, Application Insights, and distributed request tracing. Enable engineers to quickly diagnose and resolve production issues.
• Optimize our platform for reliability and scale by improving AKS workloads, Horizontal Pod Autoscalers, RabbitMQ clusters, and SQL Server infrastructure to handle significant traffic spikes during key seasonal events.
• Implement and maintain secure cloud environments through Azure Key Vault, IAM/RBAC, network segmentation, and infrastructure best practices.
• Help ensure the secure handling of payment-related traffic while continuously strengthening our cloud security posture.
• Help modernize our platform by migrating legacy .NET Framework services running on Azure VMs to containerized .NET 10 workloads on AKS.
• Build on the modernization patterns already established across our backend services.
• Collaborate across engineering teams to solve complex operational challenges, improve platform capabilities, and foster a strong DevOps culture throughout the organization.

Requirements

• You are an excellent communicator and collaborator. We work in English, but you will hear many languages in our Stockholm office.
• 5+ years of experience in Platform Engineering, DevOps, Site Reliability Engineering, or a similar role.
• Strong hands-on experience with Azure, including AKS, ACR, Key Vault, networking, and identity management.
• Deep understanding of Kubernetes, container orchestration, Helm, and Infrastructure as Code with Terraform.
• Experience building and maintaining CI/CD pipelines using GitHub Actions and/or Azure DevOps.
• Strong understanding of observability practices, including logging, metrics, tracing, alerting, and production incident management.
• Solid understanding of Linux, Windows Server, networking, and cloud security principles.
• Experience deploying and operating modern .NET applications is considered a strong advantage.
• You have a proactive, ownership-driven mindset and remain calm and effective when solving complex production challenges.
