Senior Platform Engineer

Hello. We’re World First and we’re a bit different from the rest…

We’re not your typical financial services company. As a matter of fact, we pride ourselves in being different. We are the UK’s fastest growing foreign exchange specialist and we make moving money around the world faster, easier, safer and just all-round better.

We have awesome relationships with our thousands of customers, as well as with our suppliers, partners and colleagues. It is – and always has been – people first. 
You’ll love our culture and passion, and we can’t wait to have you on board.

The role:

World First is a market-leading, award-winning, bank-beating, rapidly growing, fun-loving international payments company and we are looking to hire a Platform Engineer.

The Platform Engineering team at Worldfirst are responsible for the end to end health of our systems and services that are required to be available 24X7.  Located in London and Hong Kong, the team works as one team, balancing local priorities and workload with a goal of standardising technology and methodology globally.

As a Platform Engineer at Worldfirst you will play a critical role in the delivery of our enterprise products and services to our large and growing global customer base as part of the Global Platform Engineering team.

You will join the Cloud Squad who are currently building the cloud-native future of World First.  This Greenfield project will build a fully automated, highly available platform in AWS with a container-first mindset.  As our monolithic applications are split in to smaller services, you'll be working with colleagues in Software Engineering, Product Management and Information Security to deploy those using standardised pipelines to the new platform.  Once live, you'll be monitoring, improving and supporting the applications using tools such as New Relic and ELK.

This is an opportunity to work within an extremely dynamic environment and the role expects you to be efficient, engaging and flexible.  You will have the opportunity to have a direct influence on day to day operations, driving automation and the transition of traditional infrastructure to the cloud.
