Network & Security Engineer (pfSense / OPNsense)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Network & Security Engineer (pfSense / OPNsense) based in Germany.

We are seeking an experienced Network & Security Engineer to manage, secure, and optimize network infrastructure in a fully remote environment. In this role, you will oversee firewall operations, VPN connectivity, routing, switching, and network design across internal and customer environments. You will use your hands-on expertise with pfSense and OPNsense to implement secure configurations, troubleshoot complex connectivity issues, and improve network reliability. Working closely with security operations specialists, you will help investigate firewall logs and respond to potential security incidents. You will also introduce automation, maintain thorough technical documentation, and support the development of your teammates. This opportunity suits a technically strong professional who values practical expertise, continuous improvement, and collaborative IT operations.

Accountabilities:

- Manage day-to-day network and firewall operations while contributing to infrastructure projects and technical improvements.

- Independently implement, configure, maintain, and document IPSec VPNs and firewall rules using pfSense and OPNsense.

- Design and document network environments for customer and internal projects, ensuring configurations and implementation plans are documented before deployment.

- Perform advanced network troubleshooting, including deep packet analysis and the resolution of complex routing, switching, and VPN connectivity issues.

- Configure and maintain network infrastructure involving IPv4, IPv6, dynamic routing protocols, and switching technologies.

- Introduce and develop basic network automation using tools such as Ansible, Python, or Bash to streamline deployments and operational workflows.

- Collaborate with the Security Operations Center (SOC) team to analyze firewall logs, investigate security events, and help mitigate incidents.

- Identify opportunities to improve network configurations, technical designs, security practices, and operational efficiency.

- Train and onboard new colleagues, share technical knowledge, and contribute to the team's professional development.

- Participate in a rotating duty schedule with the Network Operations Center (NOC) and SOC teams, including nights, weekends, and public holidays.

- Take on additional responsibilities when needed to support colleagues, strengthen team capabilities, and expand technical expertise.

Practical, in-depth technical expertise is valued more highly than certifications. Seniority is assessed primarily through demonstrated skills and experience rather than years of service alone.
