We are an AI-first company, part of the Visma group, with offices in Vila Real and Seia.

What you'll do

As a SysAdmin, you make sure the infrastructure serving more than 40,000 businesses is available, secure and ready to grow. You will work as part of a team to keep our servers, network and cloud services running smoothly.

Your responsibilities

Operations and availability

• Administer, maintain and update Linux (Ubuntu) servers in production.
• Monitor systems and services, set up alerts and act before an issue reaches the customer.
• Manage backups and disaster recovery plans, and test them regularly.
• Respond to incidents, find the root cause and make sure they don't happen again.

Security

• Apply patches, hardening and security best practices across servers and network.
• Manage privileged access and credentials, following the principle of least privilege.
• Comply with the Visma group's security standards.

Automation and cloud

• Automate repetitive tasks with scripting and infrastructure as code.
• Support operations on Google Cloud Platform and the evolution of our infrastructure.
• Work with Engineering on deployments, pipelines and application performance.

Documentation and knowledge sharing

• Document systems, procedures and runbooks, so that no one depends on a single person.
• Use AI tools in day-to-day operations, like the rest of the team.

What we're looking for

Essential

• A degree in Computer Engineering, Networking, Telecommunications or a related field, or equivalent experience.
• 3+ years administering Linux servers in production, ideally Ubuntu or Debian.
• Solid networking knowledge: TCP/IP, DNS, firewalls, VPN and load balancing.
• Experience with web services and databases in production.
• Experience with monitoring, alerting, backups and disaster recovery.
• Scripting for automation, in Bash and/or Python.
• Working proficiency in Portuguese, and technical English, written and spoken.
• Availability to join a shared out-of-hours on-call rota.

Nice to have

• Experience with Google Cloud Platform (Compute Engine, Cloud SQL, IAM, VPC networking).
• Infrastructure as code (Terraform, Ansible).
• Containers and orchestration (Docker, Kubernetes).
• CI/CD pipelines.
• Certifications such as LPIC, RHCSA or Google Cloud Associate Cloud Engineer.
• Experience with security standards (ISO 27001, NIS2).
• Soft skills that make the difference
• Calm under pressure: when a system goes down, you're the one who thinks clearly.
• Responsibility: you follow every issue through until it's solved, and you know when to escalate.
• Documentation discipline: you write so that others can do what you do.
• Clear communication: you can explain a technical problem to a non-technical person.
• Curiosity: you love learning, including new ways of working with AI.
• Team spirit: you work well in pairs and with Engineering.
