Senior Machine Learning Engineer

Who are we?

WorldRemit is changing the way people send money abroad. We’ve taken something complicated and made it simple, so that sending money is as easy as sending a text message  Tap the WorldRemit app or head to  on our website, and your international transfer is made – to a bank account, cash pickup, Mobile Money, or airtime top-up. Founded in 2010, we send international remittances from 50 countries to more than 150 countries and we continue to expand our footprint.

Using WorldRemit is easy because we do the hard part, connecting hundreds of banks, money agents, mobile operators and payment systems around the world. These were never designed to work together, but WorldRemit makes it happen.

WorldRemit has grown - on average - by 50% year on year and is now processing over £3.1bn of remittances on an annualised basis.  WorldRemit’s success, and the size of the market it is operating in, means it has attracted investment from the world’s leading technology and impact investors, Accel, Technology Crossover Ventures (TCV) and Leapfrog with $370m invested to date. We currently employ close to 1,000 employees and have offices in London, USA, Philippines, Poland, Australia, New Zealand, Canada, Japan, Hong Kong and other locations.

The journey is just beginning. We believe in faster, simpler, more accessible money transfers. That means building better products and services for our customers. 

Changing the world isn’t easy – so we only hire the most talented people. You need to think differently, believe in new solutions to old problems, and have the drive to make them happen. We aim to attract, retain and develop people that can bring to life our values: 

• Aim high - We dream big, think bold and go the extra mile
• Embrace challenge - We ask questions, start conversations, and always love to learn
• Do what’s right - We act with integrity, building trust in ourselves and in our business
