Senior Network Engineer

Our client is a major, rapidly growing international shipping group headquartered in Piraeus, operating a modern global fleet and undergoing full-scale digital transformation across its shore and marine operations. Recently relocated to brand-new, modern corporate offices in Piraeus, the group is heavily investing in next-generation infrastructure and global connectivity.

You will join an established IT department of over 20 professionals across specialized teams. This is a dedicated networking specialist role offering genuine technical ownership over global network architecture and core security operations.

The Role

Reporting to the Office IT Manager with a functional line to the Vessel IT Manager, you will serve as the hands-on technical owner for network and network security infrastructure across shore offices, international hubs, and cloud environments. Designed for a proactive specialist rather than a generalist systems administrator or hands-off advisor, this role balances greenfield architecture with complex troubleshooting.

In your first six months, you will take ownership of core Fortinet and SD-WAN operations, lead technical RFPs for upcoming network projects, and roll out a standardized global network model starting across two initial countries before scaling to Brazil, Romania, and Athens HQ. You will also act as the internal escalation point for the Vessel IT team, advising on fleet connectivity and coordinating with external satcom and telecom partners.

Key Responsibilities

• Design, deploy, and administer the Fortinet Security Fabric ecosystem, SD-WAN, SASE remote access, and Zero Trust frameworks
• Build and roll out a standardized global multi-site network model across international offices and cloud infrastructure
• Lead technical RFPs for networking solutions with end-to-end ownership of vendor evaluation and integration
• Oversee hybrid connectivity between shore offices, global vessels, and Microsoft Azure
• Act as the internal escalation point for the Vessel IT team, troubleshooting connectivity issues, defining policies, and liaising with external providers
• Maintain network security controls supporting ISO 27001, Disaster Recovery/BCP, and maritime cybersecurity compliance (IMO, IACS UR E26/E27, GDPR)
• Produce clear network documentation and attend vessels in Greece or abroad when required (up to 2–3 trips per year) for upgrades or audits

What You'll Bring

• 5+ years of dedicated, hands-on network engineering and security experience, including 2+ years in a senior or lead capacity
• Deep, practical mastery of Fortinet solutions (FortiGate, FortiSwitch, FortiAnalyzer, FortiEDR) and building SD-WAN architectures from scratch
• Strong hands-on background in SASE, remote user access, and Zero Trust security principles
• Proven experience designing multi-site networks alongside solid knowledge of Azure cloud networking, Microsoft 365, and basic virtualization (VMware/Hyper-V)
• Bachelor’s degree in Computer Science, Engineering, or a related field (AEI preferred, TEI considered; MSc is a plus)
• Proactive mindset, strong ownership, and fluent Greek and English

Nice to Have

• Prior maritime/shipping experience (multi-WAN Fortinet setups at sea, VSAT/LEO satellite communications,  training is provided if coming from another sector)
• Fortinet (FCP/FCSS) or Cisco (CCNA/CCNP) certifications
• Exposure to ISO 27001 audits, SIEM/SOC, EDR/XDR, or PowerShell/Python scripting
