Firewall Engineer

We’re on a mission to become the leading technology partner for the global energy sector. By combining deep technology expertise with domain knowledge, we’re driving digital transformation and enabling the green transition—and we’re just getting started.

As part of our growth strategy, we’re looking for a dedicated firewall engineer to strengthen our global Operations team. If you’re passionate about network security, thrive on solving complex challenges, and want to help customers succeed by implementing robust, future‑ready firewall solutions, this is the role for you.

About the Role

In this position, your primary focus will be on firewall technologies and network security for our global customers in the energy sector. You’ll work with industry‑leading platforms such as Check Point and Palo Alto, ensuring secure, reliable connectivity across diverse environments—onshore, offshore, and cloud.

You’ll join a team of network specialists responsible for designing, configuring, and maintaining advanced network and IT solutions. From implementing VPNs to managing intrusion prevention systems, your work will have a direct impact on safeguarding critical infrastructure.

Collaboration is key: you’ll work closely with vendors, customers, and internal teams, while also mentoring junior colleagues.

Key Responsibilities

• Design, configure, and implement firewall solutions using Check Point and Palo Alto technologies.
• Manage and maintain security components, including VPNs (IP‑VPN, SSL‑VPN, IPSEC‑VPN) and intrusion detection/prevention systems.
• Troubleshoot and optimize firewall performance across LAN, WAN, and hybrid environments.
• Provide 3rd line support for complex security incidents.
• Ensure compliance with security protocols and best practices.
• Contribute to wider network tasks and tickets when required.

Who You Are

We’re looking for a motivated professional with deep expertise in firewall technologies and network security. To succeed in this role, you should bring:

• Extensive experience with Check Point firewalls (configuration, administration, troubleshooting).
• Hands‑on experience with Palo Alto Networks firewalls; additional exposure to Cisco, Juniper is a plus.
• Strong knowledge of VPN technologies and secure network design.
• Familiarity with identity solutions (e.g., Cisco ISE) and wireless security standards.
• Advanced certifications such as Check Point CCSA/CCSE, or Palo Alto PCNSE are highly desirable.
• Experience with network monitoring tools (e.g., Zabbix, NetFlow) beneficial.

Nice‑to‑Have

• Experience automating firewall tasks for efficiency.
• Exposure to rigs/vessels and the oil & gas/energy sector.
