We are looking for a DevOps Engineer to lead the automation of our hybrid infrastructure in our offices in Warsaw/Poland or Belgrade/Serbia. You will be responsible for managing a diverse environment that includes both AWS cloud services and on-premise bare-metal servers. A significant part of this role involves evolving our database operations—moving away from manual tasks toward a fully automated, scalable, and observable data platform.

Key Responsibilities:

• Hybrid Infrastructure Management: Design and maintain IaC for both AWS (RDS, EC2) and physical bare-metal servers using Terraform/Terragrunt and Ansible.
• Advanced Automation & Scripting: Develop custom tools and scripts (using Python or Go) to automate complex workflows that off-the-shelf tools can't handle.
• Database Lifecycle Automation: Automate provisioning, configuration tuning, and schema migrations. Work closely with DBAs to eliminate manual toil through code.
• Observability: Build and maintain high-fidelity monitoring for databases and system health using the Prometheus stack.
• Security & Compliance: Centralize secret management and access control using HashiCorp Vault.
• Knowledge Sharing: Act as a subject matter expert, documentation enthusiast, and mentor for the team as we evolve our infrastructure practices.

Technical Requirements:

• Experience: 3+ years in DevOps/SRE with a focus on infrastructure automation.
• Hybrid Ops: Proven experience managing both Cloud (AWS) and On-prem (Linux bare-metal) environments.
• Tooling: Expert-level knowledge of Ansible and Terraform/Terragrunt.
• Development Skills: Strong proficiency in Python or Go for infrastructure scripting and internal tooling.
• Linux Internals: Deep understanding of Linux systems, disk I/O optimization, and networking.

Nice to Have (The "Extra Mile"):

• Kubernetes (K8s) Expert: Hands-on experience with K8s (EKS or self-managed).
• Databases in K8s: Experience (or a strong desire to lead the transition) of running stateful workloads (Databases) inside Kubernetes using Operators or Helm.
• Mentorship: A passion for teaching and sharing K8s/Automation best practices with colleagues to level up the entire team.

What We Offer:

• The chance to work on complex, high-load systems where "manual" is a forbidden word.
• A collaborative environment where your architectural decisions directly impact the stability of the product.
• Modern stack and the freedom to introduce new tools that solve real problems.
