Back-End Developer

An industry (and opportunity) like no other

Responsible for enabling over 90% of global trade, maritime touches every part of our lives. Quite simply, without commercial ships, half the world would freeze, and half the world would starve.

The shipping industry is also responsible for a significant proportion of the global climate change crisis, and therefore a substantial proportion of the solutions that are so urgently needed. More than three percent of global carbon dioxide emissions can be attributed to ocean-going ships. This is an amount comparable to major carbon-emitting countries.

Following a decade of rapid growth, StratumFive now services in excess of 12,000 vessels. As a leading maritime tech company, we therefore have a key part to play in unlocking every possible efficiency, reducing fuel consumption and lowering vessel emissions through digital innovation – epitomised by our groundbreaking new β€˜Podium’ platform.

StratumFive also plays a critical role in protecting the safety of seafarers, cargo, and the marine environment, by providing expert routing advisory services directly to the vessel via our new 24/7 New York meteorological operations centre.

Working in maritime is exciting, rewarding, interesting, and unlike any other industry. With the sector expected to double in size to $3trn by 2030, StratumFive are looking for the next generation of innovators and problem solvers to join our mission and take pride in helping shape the future of our planet, and this most important of industries.
