DSL-01 is in full development. This applies not only to the plant but also to the organization and the employment conditions. Our HR team is working on a suitable and market-competitive package for the location in Delfzijl.

You can count on a good salary, a bonus scheme, and employment conditions that offer room for your professional and personal development.

Work with one of the first large-scale SAF plants in Europe. You will contribute to the construction of DSL-01 in Delfzijl: a plant focused on the production of Sustainable Aviation Fuel and by-products.

As an OT Engineer, you will play a key role in designing, implementing, and managing the Operational Technology (OT) environment of DSL-01.

Your focus is clear: a reliable OT environment that is safe, available, and future-proof.

In Delfzijl, we are building DSL-01, a SkyNRG plant for renewable fuels. Here, we produce Sustainable Aviation Fuel (SAF) from waste streams such as used fats and oils, using HEFA technology. Additionally, we produce by-products such as butane, propane, and naphtha.

DSL-01 will be the first plant in Europe fully focused on SAF and associated sustainable by-products. Once the plant is operational, we will produce 100,000 tons of SAF and 35,000 tons of by-products annually. With this, we reduce greenhouse gas emissions by approximately 80% compared to fossil kerosene, measured across the entire chain.

Construction started in 2026 and the first production is planned for 2028. The project includes the plant itself, associated pipelines, and temporary work sites. You will contribute directly to the realization of a new industrial plant and the sustainability of aviation.

We work according to international standards and Dutch laws and regulations to carefully manage the impact on people, nature, and the environment. Safety, sustainability, and collaboration are central to this.

This position connects two phases of the project. During the construction of DSL-01, you will help make important design choices for the OT environment. After commissioning, you will be responsible for supporting, managing, and continuously improving the operational technology within the factory.

During the construction of DSL-01, you will contribute to the development of the OT architecture and the preparation of the operational phase.

Your responsibilities include, among other things:

• Translating OT and cybersecurity requirements into supplier specifications, contractor scopes, and technical designs

• Performing OT risk analyses and defining network segmentation, zones, and data flows within the OT landscape

• Reviewing designs, network architectures, and technical documentation from suppliers and integrators

• Designing OT networks, IT/OT DMZ structures, and secure remote access for suppliers and support parties

• Participating in FAT and SAT testing and supporting commissioning activities

• Developing standards for configuration management, backup, and recovery procedures

• Contributing to the integration of systems such as DCS, PLC, MES, EAM, LIMS, and Historian platforms

• Drafting operational procedures for change management, patching, monitoring, and incident handling

You will lay the foundation for an OT environment that is safe, stable, and manageable from the very first day of production.

After the commissioning of the factory, you will be responsible for the management and further development of the OT environment.

Your responsibilities include, among other things:

• Supporting and managing OT systems within the factory

• Monitoring the availability, reliability, and security of production and control systems

• Coordinating changes, updates, and maintenance activities within planned maintenance windows

• Collaborating with operators, engineers, and maintenance teams during technical failures and improvement processes

• Managing OT assets, documentation, and technical standards

• Supporting OT monitoring, risk management, and cybersecurity measures

• Investigating OT-related incidents and implementing structural improvements

• Collaborating with IT Infrastructure and IT Security to keep the OT environment safe and future-proof

• Participating in a periodic on-call service (24/7 support)
