Do you want to play a key role in securing the latest generation of bridge and navigation systems on board vessels worldwide? As a Maritime OT Cybersecurity Engineer at Alphatron Marine, you will work at the intersection of cybersecurity, network technology, and maritime innovation. You will translate complex cybersecurity requirements into secure, reliable solutions that are deployed daily on ships across the globe.

Your mission as a Maritime OT Cybersecurity Engineer!

On behalf of Alphatron Marine, MARPRO Group is looking for a Maritime OT Cybersecurity Engineer for the office in Rotterdam.

The company

At Alphatron Marine / JRC, you will make a direct impact on the future of cybersecurity on board vessels. You will serve as the technical backbone, ensuring that our Integrated Bridge Systems, navigation systems, and OT networks function safely and reliably on board ships, in compliance with relevant cybersecurity standards and classification society requirements.

The environment is dynamic. One moment you might be preparing firewall rules and VLAN schemes for a newbuild project; the next, you could be collaborating with shipyard technicians, R&D engineers, or surveyors from classification societies to commission IEC 61162-460 gateways and secure bridge networks.

Within our Project Management department, you will play a vital role in ensuring that our bridge and navigation systems are cyber-resilient, meet applicable IACS UR E26/E27 and classification society requirements, and are securely integrated to support safe and reliable vessel operations.

The Job

We are looking for a Maritime OT Cybersecurity Engineer to join and strengthen our Project Management department. In this role, you will serve as the technical lead for the network architecture, configuration, and cybersecurity setup of maritime OT (Operational Technology) infrastructures. This includes Type-Approved managed switches, IEC 61162-460 gateways, perimeter firewalls, and secure Ethernet networks integrated into our solutions and navigation control systems.

You will act as a key technical liaison between project managers, commissioning teams at shipyards, R&D engineers, suppliers, and classification societies such as DNV, ABS, and Lloyd’s Register. In this capacity, you will facilitate the successful completion of cyber-resilience assessments and approval processes in accordance with project-specific requirements.

Your responsibilities

• Lead the technical design, definition of security policies, setup of DMZs, and configuration of firewall rules for IEC 61162-460 gateways, OT firewalls, and managed industrial switches within bridge integration projects and onboard OT networks.

• Develop and implement network segmentation, security zones, and conduits in compliance with IACS UR E26/E27 standards and classification society requirements. This involves utilizing OT firewalls and secure network architectures to manage and protect communication between critical navigation systems (such as ECDIS, Radar, Autopilot, and VDR), shipboard IT, and external communication networks like VSAT and Starlink.

• Oversee and provide support to shipyard technicians, installation engineers, and commissioning teams during onboard installation, ensuring that OT firewalls, gateways, and switches are correctly installed, configured, and tested according to project specifications. Preparing and submitting technical project documentation—including network topology diagrams, IP/VLAN schemes, asset inventories, and OT firewall rules—for review and approval by classification societies.

• Troubleshooting network, firewall, and connectivity issues during integration and commissioning activities.

• Participating in Factory Acceptance Tests (FAT) and onboard Site Acceptance Tests (SAT) to validate secure data flows between navigation equipment, OT firewalls, and vessel communication networks.

Professional qualifications

• The ideal candidate has at least 3 years of experience in maritime network engineering, OT/ICS cybersecurity, maritime electronics integration, or a similar systems delivery or project engineering environment.

• Ideally, you possess practical knowledge of IACS UR E26/E27, IEC 61162-460, and the principles of IEC 62443, combined with hands-on experience configuring maritime or industrial OT firewalls, gateways, and managed switches from vendors such as Moxa, Robustel, Veinland, or similar.

• Thorough knowledge of VLANs, ACLs, firewall policy configuration, network segmentation, redundancy, and secure network architectures.

• Practical experience with maritime communication protocols—such as IEC 61162-450/460, NMEA 0183, NMEA 2000, and Modbus TCP—is an advantage.

• Strong communication skills are essential, particularly when collaborating with shipyards, R&D departments, installation teams, and surveyors from classification societies. Relevant certifications such as CCNA/CCNP, GICSP, or IEC 62443 Specialist are a strong advantage.
