Job description:
The main application you will be working on is a scalable, high-performance API for supporting large-scale e-commerce websites (thousands of API calls per second). The API has features e.g., product catalog, shopping cart, and checkout. It is a rewrite of functionality in an existing application, which the same team is maintaining and migrating the functionality piece by piece. The old application has grown organically with changing requirements, and we have decided to rewrite the API functionality from the ground up, with a changed architecture. We are implementing the main business logic as a GraphQL API written in PHP 8 on top of a MariaDB database. We use ElasticSearch and Redis and a lot of caching to produce an API that is very performant and hard to kill. We will generate events using change data capture with Debezium and feed those through Kafka. On top of this, we are implementing a caching proxy as a Cloudflare Worker using TypeScript.
We work according to Scrum and our teams are self-organizing, meaning the teams themselves decide on what tech stack to use for a particular project and how to best deliver. We are all very ambitious and love to learn, and we hope you do too. We spend a lot of time coaching each other, pair programming, and sharing knowledge.
