About the role

The Role

Work directly with the CEO and CTO to build systems that turn maritime data into actionable decisions.

We help vessel operators direct their vessels to the right port, so they can save money, spend less resources, and serve their crew better. We do this by relying on information about vessel positions, types, fuel consumption, flight data, travel restrictions, and much more. Our first innovation in this industry has been in building structured data out of broken pieces of information that was previously stuck in data warehouses, PDFs and websites, and in building relationships between them.

There are two things that come first for us as a company: data and user experience. If you can ingest information and build software that understands what it's holding, the algorithms are often apparent. It's this direction that helps us process millions of datapoints across two thousand vessels, 50,000 crew for hundreds of users in real-time, all from a VM with four cores and 16 GB of RAM. We've integrated over fifty sources, from piracy datasets to agency costs, and have another twenty currently in the pipeline.

Your primary task with us will be to build ingest and integration pipelines for these data sources, to reason about the incoming information, and to direct how they will be used.

Who are we?

Greywing is a maritime intelligence tool that enables ship managers to conduct operations and save thousands of dollars by providing actionable insight into the decisions they make. Simply put, we process hundreds of thousands of points of information about a vessel to tell them where it should go and what it should do.

We are backed by the people at Y Combinator, Instacart and Flexport. We work with the world's largest ship managers and operators to make the global shipping network more efficient while protecting the people who make sure our world runs smoothly.

In the past year, we've conducted charter flight operations for vessels calling at Singapore, helped evacuate wounded crew that would not have been possible otherwise, and saved hundreds of thousands of dollars in wasted fuel and resources.

The Team

He has also built software and hardware serving hundreds of thousands of users across southeast Asia, in fintech, insurtech, robotics, for companies like National Geographic, Ethereum, and SGX.

Why you should join Greywing

Greywing is a digital platform that tracks ships and optimises everything that gets on or off.

We connect hundreds of public and private data sources - like satellite tracking, crew and fuel reports, GDS, and port restrictions - to provide immediately actionable intelligence on vessel operations.

Our efforts are currently focused on making crew changes cheaper and faster, and in making sure the thousands of men and women who keep our economies functional get home safely to their loved ones.

We work with two of the largest ship operators globally to digitize their operations. They give us the real life experience to automate their businesses and our vision is to deploy the same techniques to the long tail, creating a single operational platform for shipping.
