Descripción del empleo

How You’ll Have Impact

• Build the Platform Behind the Platform: Design and evolve the cloud infrastructure that powers our multi-tenant SaaS ecosystem.
• Enable Engineering Velocity: Improve CI/CD pipelines, developer experience, and deployment automation.
• Drive Reliability & Observability: Ensure high availability, performance, and real-time visibility across distributed systems.
• Architect for Scale: Design infrastructure that supports growth, AI workloads, and distributed services.
• Champion Infrastructure as Code: Everything reproducible, versioned, and automated.
• Embed Security by Design: Implement DevSecOps best practices across the delivery lifecycle.

What You’ll Do

• Design, implement, and maintain cloud infrastructure in AWS and/or Azure.
• Manage and optimize containerized workloads using Docker and Kubernetes.
• Build and evolve CI/CD pipelines (Jenkins, GitHub Actions, Bitbucket Pipelines, GitLab CI or equivalent).
• Implement Infrastructure as Code (Terraform or similar).
• Ensure high availability, disaster recovery, and backup strategies.
• Improve monitoring, logging, and alerting systems (ELK stack, Grafana dashboards and alerting, Azure Monitor / Log Analytics, Amazon CloudWatch and other observability tools).
• Operate, monitor, and tune Microsoft SQL Server databases (performance, backups, high availability).
• Optimize system performance, scalability, and cost efficiency.
• Collaborate closely with backend engineers (Java / Kotlin, C#, Node.js) to improve deployment patterns and runtime reliability.
• Automate operational processes and reduce manual intervention.
• Leverage AI-assisted tooling (Claude, Codex, automation agents, anomaly detection systems) to improve operational efficiency.
• Participate in architectural discussions to ensure infrastructure scalability and resilience.

You don’t just maintain infrastructure — you engineer the reliability of the business.

We run workloads on both AWS and Azure. We are looking for solid hands-on experience with IaaS and core managed cloud services on at least one of them — knowing the equivalent on the other cloud is a strong plus. These are the building blocks you’ll work with:

• Virtual networking — Azure: VNet, NSGs, VNet Integration, Private Endpoints | AWS: VPC, Security Groups, PrivateLink
• In-memory cache — Azure: Azure Cache for Redis | AWS: Amazon ElastiCache (Redis / Valkey)
• Managed SQL Server — Azure: Azure SQL / SQL Managed Instance | AWS: Amazon RDS for SQL Server
• Workload identity (secretless auth) — Azure: Managed Identity + DefaultAzureCredential | AWS: IAM Roles (instance profiles, IRSA) + SDK default credential chain
• Secrets & keys — Azure: Key Vault | AWS: AWS Secrets Manager / KMS

• 5+ years of experience in DevOps / Cloud Engineering roles.
• Strong hands-on experience with AWS or Azure — experience with both is a strong plus.
• Deep understanding of containerization and distributed systems, with production experience in Kubernetes (required).
• Proven experience building and maintaining CI/CD pipelines (Jenkins, GitHub Actions, Bitbucket Pipelines, GitLab CI or similar).
• Experience implementing Infrastructure as Code.
• Hands-on experience with Microsoft SQL Server (administration, performance tuning, backup/restore, high availability).
• Experience with Redis in production (caching, session storage, pub/sub).
• Strong knowledge of networking, security, and system architecture.
• Experience working in high-availability SaaS environments.
• Solid understanding of observability, monitoring, and incident management, including Grafana dashboards and alerting.
• Experience collaborating with backend engineering teams.
• Languages: fluent Spanish and professional English (both required).

We don’t expect you to master every tool listed above, but we do expect solid hands-on experience with at least one technology in each area: cloud provider (AWS / Azure), containers & orchestration, CI/CD, Infrastructure as Code, observability, and databases & caching.

Nice-to-Have Superpowers

• Experience implementing DevSecOps practices.
• Familiarity with AI/ML infrastructure requirements.
• Experience with cost optimization strategies in cloud environments.
• Knowledge of GitOps workflows.
• Experience in multi-tenant SaaS platforms.
• Hands-on experience with both AWS and Azure.
• French — a huge plus (we can dream!).
