About the role

The Role

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

To evaluate a single port in Greywing, we calculate the fuel consumption, travel restrictions for each crew member, flight costs to each probable destination, past price history for flights, agencies, and collate 30 other public and private data sources. We then do it across 200,000 ports, 100,000 airports, and thousands of crew members to evaluate a single vessel. We then do it for two thousand vessels and fifty thousand crew.

We do this in realtime, with a single VM with four cores and 16 GB of RAM serving our entire customer base. We do this through a deep understanding of system design, architecture, and through data-aware modules that compute only what they need to and when they need to.

We'd like you to help us make it better. With us, you would be creating systems that absorb the complexity of directing hundreds of thousands of tons of steel and iron, as well as millions of dollars in cargo, to help the men and women who keep our world moving.

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.

For the insatiably curious, you may find more information on our blog or our CTO's Writing.

The Team

Our CEO is a former Royal Marine Commando that has built a business in maritime from nothing to 4 million in turnover.

Our CTO has published multiple papers across technology, from Formal verification in cryptocurrencies, human-computer interaction, embedded glucose monitoring to baseline optimization in chemistry and physics. 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.

Our Stack

Backend: NodeJS, Express, Postgres, Redis


Full time role, fully remote if outside Singapore. Payment and salaries are compatible with Gitlab's compensation calculator, with competitive equity.

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.
