React Developer: Maritime Software Engineering

About Us

DHI is an independent, international consultancy with over 60 years of experience developing computational models for water environments. The Digital Marine team builds cloud-based systems for maritime operations. NCOS ONLINE functions as a digital twin of port environments, running simulations that predict vessel behaviour based on current and forecasted conditions. The system enables data-driven decisions with demonstrable improvements in operational safety and efficiency.

Technical Challenges in Maritime Technology

In DHI's Digital Marine Team in Malaysia, we're applying modern web technologies to solve complex maritime challenges. Our work combines advanced weather modelling with real-time data processing to create tools that support critical decision-making in ports worldwide.

Technical Environment & Challenges

Our flagship system, NCOS ONLINE, processes environmental data and hydrodynamic models to predict vessel behaviour with high precision. The system integrates multiple data sources including:

• Real-time meteorological and oceanographic data feeds
• Complex forecast models
• Vessel specifications and performance characteristics
• Port infrastructure constraints

You will be tackling several technical challenges:

• Visualizing complex data in intuitive interfaces that enable quick, informed decisions by maritime professionals
• Implementing sophisticated state management for complex user interactions to screen different levels of risk
• Developing reusable software that can be applied across many clients with varying requirements

Recently, one of our solutions was recognized with the Innovation Excellence award for Australia Infrastructure by helping optimize vessel routes, resulting in measurable emission reduction, helping to make shipping greener.
