at Wartsila

🏢 About Wartsila

Wartsila is a global leader in innovative technologies and lifecycle solutions for the marine and energy markets, with a strong commitment to decarbonization and sustainability. Working here means contributing to cutting-edge systems that enable cleaner and more efficient maritime operations, directly impacting global environmental goals.

About This Role

As a Software Engineer on this team, you'll design and implement critical software components for sensor integration and real-time data processing in maritime systems. Your work on radar/ARPA, AIS, and external interfaces will directly support port management and vessel traffic services, making a tangible impact on safety and efficiency.

💡 A Day in the Life

A typical day might involve diving into the existing codebase to implement a new interface for a radar sensor, debugging a network protocol issue with a port management system, and collaborating with the team on architectural decisions for improving system redundancy. You could also be testing your changes in a simulated environment or reviewing code from peers.
