Job Description

We are looking for an experienced system engineer to develop, enhance and maintain No-IP's core infrastructure. This role has both system administration and development aspects. We are a network service provider focused on dynamic DNS, and are extending into other service offerings.

Responsibilities

• Develop a deep understanding of No-IP’s products, infrastructure, architecture, and business needs.
• Build, operate, and maintain compute infrastructure, including virtualization platforms, networking, web servers, and supporting systems such as databases, mail, logging, analytics, certificate management and caching components.
• Maintain and evolve infrastructure in an automation-first environment.
• Proactively modernize infrastructure by identifying single points of failure, retiring legacy systems, and aligning platforms with best practices.
• Operationalize new technologies in development and production in a scalable, maintainable manner. Evaluate technologies and advise teams on effective usage.
• Own application delivery and supporting platforms, including the website, customer and admin portals, and internal tools such as Metabase, Kibana, and Grafana.
• Provide technical leadership and mentorship across the infrastructure domain.

Must Have

• Linux system administration: Strong experience in Ubuntu-based environments, including command-line usage, shell scripting, git, SSH, systemd, iptables, debugging tools, and core Linux concepts (file permissions, inodes, sockets, networking).
• Configuration management: Hands-on experience with tools such as Salt, Terraform, or similar systems.
• Hybrid-cloud infrastructure: Experience operating bare-metal and virtualized Linux environments alongside cloud providers, including compute, storage, and networking.
• Virtualization & containers: Experience with Linux virtualization; familiarity with Proxmox, Docker, and Docker Compose preferred.
• Software development fundamentals: Ability to write and deploy scripts and small to medium-sized programs, with an emphasis on security, observability and maintainability.
• Senior ownership: Proven responsibility for multiple infrastructure domains (e.g., networking, DNS, platform services, or multi-datacenter environments), including architectural decision-making and maintainability-focused engineering.
