The infrastructure behind 5M+ users doesn't get to have a bad day. We're hiring an Infrastructure & Platform Engineer in Porto to help keep it that way — Linux, Windows, RabbitMQ, and everything that has to just work.
The infrastructure you'll run doesn't get a bad day — it's what keeps calls connecting and conversations flowing for 5M+ users across 80+ markets. We're looking for an Infrastructure & Platform Engineer, based in Porto, to help keep our platform always on. You'll bring operational responsibility, a bias for automation, and pride in systems that are robust and well-documented.

- Manage and maintain Linux and Windows servers across multiple environments.
- Plan and execute OS upgrades, patching, and lifecycle management.
Platform & Automation
- Operate and improve configuration and orchestration tools, such as Foreman / Orcharhino.
- Contribute to automation of repetitive operational tasks — reducing toil, not just documenting it.

- Support and operate RabbitMQ-based messaging platforms.
- Support and operate SQL databases.

What We're Looking For
- Strong hands-on Linux system administration in production environments — packaging, patching, logs, performance, troubleshooting.
- Solid experience with Windows Server operations, including Active Directory, DNS, DHCP, IIS, and certificates.
Lifecycle & Configuration Management
- Proven experience in server lifecycle management: OS upgrades, patch management, system hardening, decommissioning.
- Experience with configuration/orchestration tools such as Foreman, Orcharhino, or similar.
Messaging, Data & Network
- Practical experience operating RabbitMQ or similar messaging systems — queues, clustering, troubleshooting, performance.
- Practical experience operating databases such as MySQL, PostgreSQL, or MSSQL.
- Understanding of network fundamentals, load balancing, and service troubleshooting.
DNS, Certificates & Backup
- Experience with DNS management (internal and external) and certificate automation (ACME, Let's Encrypt).
- Familiarity with backup and restore solutions such as Veeam and TSM.
Monitoring
- Experience with monitoring and observability tools — Prometheus, Grafana, Elastic, or similar.
Nice to Have
- Exposure to Kubernetes or container platforms.
- Experience with CI/CD pipelines or DevOps tooling.
- Familiarity with cloud platforms (AWS, Azure).
What We Offer You
- A highly skilled, international team of engineers who take ownership seriously.
- Exposure to modern cloud, telecom, and platform technologies at scale — our platform serves 5M+ users across 80+ markets, and the work is never trivial.
- A flexible, collaborative environment with the autonomy to own your work.
- The chance to learn, grow, and deepen your technical expertise.
- A competitive salary and benefits package, aligned with your experience.
