About Tresco Engineering

Tresco Engineering builds navigation and fleet management software for European inland shipping. We’ve done that since 1994, from our base in the port of Antwerp-Bruges. Today, Tresco has become the reference in European inland shipping navigation - more than 6,000 vessels rely on our technology, logging and optimizing millions of sailed kilometers per month.

Some of our flagship products include:

• Navigis
  • navigation software and charts for inland shipping
• TrackPilot
  • semi-autonomous sailing, powered by SmartTracks, a route database built from the actual movements of thousands of vessels
• Tresco Fleet
  • vessel tracking and reporting for shipping companies, from wheelhouse to office

This product suite allows inland shipping professionals to plan and sail more efficiently, comfortably and cost-effectively. All products have been developed and optimized based on needs and feedback from our client base. Our development team works closely with our sales, support and service teams, so what we build is shaped by what skippers and shipping companies actually need and use daily.

Your role

You will design, implement, and maintain software solutions that power navigation, automation, and fleet management products for inland shipping. In this full-time, on-site role located in the Antwerp Metropolitan Area, you will work closely with support, sales and service teams to translate user feedback and business requirements into robust, scalable applications.

Your day-to-day responsibilities will include writing clean, tested code, integrating hardware and data sources, optimizing performance for real-time and geospatial workflows, and troubleshooting production issues. You will participate in code reviews, contribute to technical documentation, and collaborate with the team to continuously improve development practices and product usability.

You will also support deployment, maintenance, and iterative enhancement of existing systems based on user feedback and evolving industry standards. Furthermore, you'll coach and support junior colleagues in the development team.
