Description

Thought Machine’s mission is bold – to properly and permanently rid the world’s banks of legacy technology. To achieve this, we have developed the foundations of modern banking and built core and payments technology which runs natively in the cloud. What we are attempting is hard and means we need great people working together to build great technology.

We have grown rapidly in the past few years – growing our team to more than 500 individuals across offices in London, New York, Singapore and Sydney. We have raised more than $500m in funding and are now valued at $2.7bn. Our investors include Molten Ventures, Eurazeo, Intesa Sanpaolo, Temasek, Nyca Partners, JPMorgan Chase, Standard Chartered, and more.

We have created a culture enabling our team to produce the best work in the industry, ensuring we have fun along the way. We're regularly cited as having a fantastic workplace culture and have been recognised by Sifted magazine as having one of the highest Glassdoor ratings for a UK fintech company and the most generous employee share package in the industry. We've been named AltFi's B2B Fintech of the Year, placed in the FinTech50, and named one of Europe’s fastest-growing companies by the Financial Times in 2023.
