Lead System Administrator

At BaseNet, reliability isn’t just part of the job. It is the job.

Every day, thousands of legal professionals depend on our SaaS platform to do their work securely and efficiently. When our systems stop, their business stops. That’s why we’ve built a completely new, modern on-prem infrastructure that is robust, scalable and built for growth.

We’re looking for a Lead System Administrator who wants to take ownership of that foundation and evolve it further. Someone who combines deep technical expertise with a proactive mindset and the drive to build things the right way.

What you’ll be doing

This role goes far beyond “keeping the lights on.” You’ll be shaping the future of our on-prem infrastructure, ensuring that our systems remain secure, reliable, and future-proof. You’ll have the freedom to set the standard: technically, operationally, and strategically.

Your responsibilities

• Lead and develop a distributed system administration team (Netherlands & Spain)
• Evolve and optimise our on-prem platform to maximise performance, reliability and security
• Define, document and enforce clear technical standards, playbooks and procedures
• Oversee local network and development environments for smooth engineering workflows
• Proactively detect and resolve system bottlenecks before they become problems
• Automate repetitive tasks to increase speed and consistency
• Own the infrastructure roadmap and be the key technical decision-maker

Our tech stack

• Ceph (distributed storage)
• Linux (Debian/Ubuntu)
• Proxmox (virtualisation)
• Kubernetes (container orchestration)
• Docker (containerization)
• Prometheus & Grafana (monitoring/metrics)
• ElasticSearch (logging/search)
• FortiMail / FortiGate (security/firewall)
• LDAP (identity management)
• GitLab (source control/CI/CD)

BaseNet is part of Blinqx, a fast-growing tech group that connects specialist software companies across different industries. Within BaseNet, we develop SaaS solutions tailored for the legal market, software that helps law firms manage cases, clients and communication seamlessly.

As Lead System Administrator you will be part of the engineering team, reporting directly to the CPTO of BaseNet. You will lead a distributed team of 5–6 system administrators in the Netherlands and Spain, combining remote collaboration with local coordination from our Amsterdam office.

Our culture is open and collaborative: clear communication, shared ownership, and space to innovate. Our office is based in Amsterdam, with hybrid flexibility for part-time remote work.

What you bring

• 10+ years of experience managing and operating production infrastructure
• Strong knowledge of Linux (Debian/Ubuntu), Proxmox, Kubernetes and Docker
• Solid understanding of networking, email servers, distributed storage (Ceph) and security
• Experience leading or mentoring technical teams, preferably across locations
• The ability to explain complex systems in simple terms
• A proactive mindset: you don’t wait for problems to appear; you prevent them
• Strong sense of ownership and pride in building and maintaining robust systems
• Experience in a SaaS or B2B environment is a strong plus
• Cloud and AI experience is a plus, but the core remains physical and local

What we offer

• A high-impact role within a mission-critical SaaS environment
• Hybrid working: partly from our Amsterdam office, partly remote
• Freedom to shape the infrastructure and define technical direction
• A collaborative, international team culture focused on excellence
• Clear growth paths for example towards Infrastructure Architect
