Position Summary

This role sits within the Product Development team, responsible for the design, development, testing, and maintenance of core platform components within a safety-critical maritime software suite. The platform is deployed at ports and waterways globally, and the work you do directly affects its reliability, performance, and capability.

We're looking for engineers with strong systems-level experience, a methodical approach to quality, and the ability to work effectively in a geographically distributed team.

Key Responsibilities

• Design and implement software components with focus on sensor integration, real-time data processing, and external system interfaces.
• Develop and maintain components including radar and ARPA processing, AIS data sources, network audio, direction finders, weather station integration, and recording/playback subsystems.
• Implement and support external system interfaces, including IALA IVEF target exchange, proprietary protocols, and REST/OpenAPI integrations with third-party port management systems.
• Contribute to platform architecture decisions, particularly around performance, redundancy, and high availability.
• Participate in code review, maintaining adherence to quality, safety, and maintainability standards.
• Investigate and resolve defects in live and pre-production deployments, including root cause analysis in complex, distributed environments.
• Produce and maintain technical documentation.
• Collaborate with system engineers, project delivery teams, and product management to translate customer and regulatory requirements into software solutions.

Qualifications and Experience

• Demonstrated experience developing production-grade software.
• Sound understanding of asynchronous I/O, socket programming, and protocol parsing (TCP/UDP).
• Experience developing for Windows-based platforms.
• Proven ability to work with and reason about large, existing codebases.
• Strong analytical and debugging skills in complex, multi-component systems.
• Efficient in C++.

Desirable

• Experience with real-time or safety-critical systems development.
• Familiarity with sensor communication protocols including NMEA, Modbus/TCP, or similar.
• Exposure to IALA standards, AIS protocols, or VDES.
• Background in maritime, defence, aviation, or other safety-critical domains.

At Wärtsilä we value, respect and embrace all our differences, and are committed to diversity, inclusion and equal employment opportunities; everyone can be their true self and succeed based on their job-relevant merits and abilities.
