Thought Machine, one of the UK's leading fintech companies, is undergoing a period of rapid expansion and is looking to hire our first iOS Engineer.

Our mission is to cure one of the banking industry's primary problems: its reliance on outdated IT infrastructure. Nearly every bank is stuck on a legacy IT platform, which cripples their ability to innovate and give their customers the type of service they deserve.

Our solution to this is Vault: a complete retail banking platform that is capable of being configured easily to suit the needs of any bank. We have built Vault from the ground up as a cloud native, microservice API architecture platform. Thought Machine has a deep culture of engineering excellence, and we believe it is this which delivers a solution compelling enough to engender a seismic shift in the banking industry.

Thought Machine is looking for highly talented individuals to help grow the company and achieve our ambitious goal. We pride ourselves on having an excellent internal culture, where we strive hard to create the best possible working environment; a healthy mix of great technical work, fast pace, supportive atmosphere, and of course our irreverent sense of fun.

Thought Machine hires team members of excellent calibre in every role. While a lot will be asked of you, you will benefit greatly from working in a world class team, with colleagues who excel. Working at Thought Machine is fast paced and team oriented with an emphasis in delivering the highest quality work in every role.We are looking for an iOS Engineer to join our Thought Machine Labs team. The Labs department within Thought Machine has evolved over the last 5 years and turned into a team of designers and engineers who have access to their own instance of Vault to materialise experiences of the future. These range from applications that help customers pay off their mortgage quicker, through to IoT devices to help children understand pocket money and more recently a game world to help people save money. The cloud native core banking platform of Vault is enabling Labs to communicate a new norm for experiences within the finance industry. The department is increasingly investing in new technologies to experiment with and discover possibilities that go beyond the traditions that plague retail banking today.

We are looking for someone with engineering depth and experience as well as a natural curiosity to want to play and fiddle with projects. You will need to be ready to collaborate with designers and engineers across various disciplines and levels to create transformative products. An autonomous working approach and an open mindset that is sometimes away from standard architectural patterns is valuable to us along with your skill at building products that adhere to our high standards of beauty.
