Full-stack Javascript Developer
Isle of Man
Permanent
Our client seeks a Full-Stack Javascript Developer
Role Profile:
We're looking for a great software engineer who can help our client design and build payment processing software.
It's easy to take for granted that a contactless payment can get from your card / phone to a merchant with a beep and a few seconds. By joining the team, you'll learn exactly how this works and have the opportunity to develop a system that people rely on to powers millions of card payments across the UK. This will include contactless / Chip & PIN terminals, SoftPOS “tap to phone” payments, online (ecommerce) payments and a slew of tooling to support it. You will never look at your payment card in the same way again…
The technology stack is built using Javascript, mostly running on AWS and Heroku. The back-end is a microservices architecture using Node.js (primarily Express) using a RESTful API design approach. The data layer includes Postgres and Redis. We use various AWS services including SQS, SNS and S3. Front-end clients are built using Vue.js (both Vue 2 and Vue 3). We also have a mobile app built with React Native.
Key Responsibilities:
You will be building and maintaining core payment processing software stack, from infrastructure to interface. You'll work directly with the CTO. You will have the opportunity to shape the engineering culture in line with the growth of the team and business. You'll be a key member of a cross-functional team, responsible for the full software development life cycle
