Key Responsibilities

On-Premises Infrastructure (Core Focus)

• Operate, maintain and evolve on-premises infrastructure, ensuring stability, performance and high availability.
• Administer virtualization environments based on Proxmox (KVM), including clusters, capacity planning and HA.
• Manage storage systems (SAN/NAS), including performance, redundancy, backup and recovery.
• Perform Linux systems administration, including hardening, patching, security and best practices.
• Work with networking concepts such as IP networking, VLANs, basic routing and firewalls.

DevOps & Automation

• Automate infrastructure provisioning and configuration using Ansible and Infrastructure as Code principles.
• Build, maintain and improve CI/CD pipelines.
• Collaborate closely with development teams to improve deployment, reliability and troubleshooting processes.
• Reduce manual operational tasks through automation and standardization.

Cloud Operations (Growth & Consolidation Phase)

• Operate and support public cloud environments (AWS, Azure), primarily using IaaS services.
• Work in hybrid environments (on-prem + cloud), ensuring integration, security and operational consistency.
• Apply cloud best practices related to cost management, security and reliability.
• Operate and support Kubernetes workloads, with a focus on day-to-day operations, networking, storage and troubleshooting.

Reliability, Operations & On-Call

• Ensure high levels of availability, reliability and operational excellence.
• Participate actively in a 24x7 on-call rotation (L2 support) for production systems.
• Respond to incidents, perform root cause analysis and define corrective and preventive actions.
• Implement and maintain solutions (e.g., Prometheus, Grafana) for monitoring, logging and metrics.

Collaboration & Documentation

• Work closely with engineering and product teams in a multidisciplinary environment.
• Create and maintain clear and practical documentation (runbooks, operational guides, handbooks).
• Support onboarding and promote operational and infrastructure best practices.

Key Requirements

• 7+ years of experience in infrastructure, systems, DevOps or similar roles.
• Strong, hands-on experience with on-premises environments.
• Solid experience with Proxmox (KVM).
• Strong knowledge of Linux systems administration.
• Proven experience using Ansible in production environments.
• Good understanding of networking fundamentals (IP, routing, firewalls, VLANs).
• Strong understanding of storage concepts and high-availability architectures.
• Experience with CI/CD tools (GitLab CI, Jenkins or equivalent).
• Experience with monitoring and observability stacks.
• Scripting skills (Bash, Python or similar).
• Experience with database administration (e.g. PostgreSQL, Oracle).
• Hands-on experience with container technologies such as Docker.
• Functional knowledge of Kubernetes, with an operational focus.
• Experience with public cloud platforms (AWS and/or Azure).

Profile & Mindset

• Strong operational mindset and sense of ownership.
• Comfortable working with critical production systems.
• Able to work autonomously and make technical decisions.
• Clear interest in growing cloud skills, grounded in strong traditional infrastructure experience.
• Practical, resilient and solution-oriented approach.
