We are looking for a Backend Engineer to join our team responsible for a high-performance GraphQL API (we are a SaaS product company).

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, that the same team is maintaining and migrating the functionality from piece to 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 and Go at the top of MySQL. 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.

At Centra, we have ambitious goals and are passionate about what we do. We have a lot of fun together during and outside of work. We've gotten to where we are today because of dedication, teamwork, raw talent, and our strong belief in driving innovation.

English is our working language, so you need to be a fluent English speaker. We base this position in Wroclaw, Poland. We would like to see our teams meeting in person at least 3 days a week in our super cool office.

The Backend Engineer role

To continue our quest for greatness, we need to find professional, passionate, and talented developers who can work fast and think outside the box – while always keeping an eye out for the details. This year's goals include improving our multi-tenant architecture and creating a brand new GraphQL API.

Centra provides the infrastructure for brands that want to sell globally and our team works with a global approach at its core. We build solutions and solve problems across time zones and believe that perspectives from different backgrounds/cultures drive innovation. As a Backend Engineer at Centra, you’ll have a direct impact on our product and its future success – no matter where you’re from.
