Job Description

BunkerEx is changing how the shipping industry buys the $200 billion of fuel it needs to power the global merchant fleet. We are bringing innovative financial products into this age-old market.

An opportunity has opened for 2 ambitious developers to help build our customer-facing product where shipping companies will buy fuel.

As an early employee, you will have the opportunity to shape the way we work. We have offices in London and Spain, so distributed team mindset is important. We are heavy Slack users.

If you have an interest in the ocean and shipping you will fit right in. Data geeks are also super welcome here. There is just so much data we want to consume and unlock secrets that will help us trade smarter, faster and more profitably.

We love people who can think and act independently. As an early employee, you will have loads of autonomy.

Our team is culturally diverse and international, though we all communicate in English.


  • At least 2-5 years experience in an OOP language, ideally C#. We will consider other languages, however you would be expected to learn C# on the job.

  • Git, ideally with gitflow
  • Unit testing
  • Front end - HTML, JS, AngularJS, Angular, Bootstrap, CSS
  • End to end product development experience, including use of CI/CD pipelines


  • €30-50K salary, depending on experience

  • Work from home once a week
  • Get the opportunity to do greenfield product development and have a voice in the design decisions.
  • Help create a world-first product and potentially change how shipping fuel is purchased forever.
  • There are truly challenging technical problems we are trying to solve and the reward is potentially huge.
  • Work in an A-Player environment alongside professionals who are all at the top of their game. Junior developers will receive mentoring and guidance. More experienced developers will have freedom and ownership over parts of the product.
