Fullstack Software Engineer at thirdfort

We’re on a mission to protect society from fraud and money laundering. We’ve already protected over 3 million people through life’s big transactions.   Fraud and regulation are rising, costing the UK economy over £100bn every year; this makes it more difficult for businesses to protect themselves and their clients - individuals like you and me - from fraud and money laundering.   Our co-founders Olly and Jack were led to this area when a friend was defrauded of £25K when buying their first property. At the time, anti-fraud technology didn’t exist, which meant that completing the anti-fraud checks required in these processes was largely manual. These big life moments should be exciting, but instead are often confusing and scary due to the painful process of completing these paper-based checks and the risk of fraud.   Thirdfort helps businesses to facilitate these anti fraud checks so that individuals know they can transact safely and seamlessly with professionals during these big transactions. Our anti-fraud platform provides a secure way for professionals in regulated sectors like Lawyers, Estate Agents and Accountants to transfer funds and verify sensitive information through app based document checks, facial recognition and open banking.   Over 1,500 businesses now trust Thirdfort to verify their clients. We are FCA regulated and have raised over $33m in capital from leading Fintech investors Breega and Element Ventures, as well as the founders of Zoopla, Funding Circle, Comply Advantage, Tessian, Fenergo and Fidel.     About the role: We’re looking for a FullstackSoftware Engineer (IC2) to join one of our cross-functional product teams and help us build reliable, scalable systems that protect our customers and their clients from fraud.
