Software Engineer

About us Worldwide AIS Network is a Copenhagen company building a global network of maritime sensors. Ships broadcast their identity, position, course and speed over AIS radio. Our receivers on coastlines around the world collect those messages and send them to our platform in real time. There they become a verified feed of vessel movements for our data customers. We build our own hardware and software. Every message is cryptographically verified at the sensor, so customers can trust where it came from. The same sensors detect GNSS jamming and spoofing as it happens. Many of our stations are hosted by individuals and companies around the world who are rewarded for the coverage they provide.
