What can you expect from Sqills?

## Description

Or maybe you refuse to compromise and just want it all…
That, and more, is what Sqills can offer you. At Sqills we are looking for an experienced Java Software Developer who wants to work with the latest techniques and continue challenging themselves.
An innovative way of working
At Sqills, our team works with a modern JVM stack, primarily Java and Kotlin. We use JetBrains IDEs such as IntelliJ IDEA, and for our CI/CD pipelines we use GitLab.
We use Terraform, Cloud Development Kit and Kubernetes, among others, to manage the infrastructure within AWS. We build Infrastructure as Code (IaC) and we use a combination of traditional services, Lambda, and managed services such as DynamoDB, SQS, SNS, RDS, AmazonMQ, CloudWatch, EventBridge and ELB.
We monitor services in production using New Relic, Sentry, EventBridge, and PagerDuty. We have developed our proprietary management platform, created by our dedicated platform team, which is built on top of our operational and infrastructure services. This platform seamlessly integrates monitoring tools and provides visualisation of fully distributed traces. This functionality aids us in analysing errors within our microservice landscape.
Secure development, architecture, performance, and resiliency are the pillars of our development process. This ensures that our software will continue to meet and exceed expectations in the future.
What will you do?

 + You will be part of one of the Agile DevOps teams. Teams consist of a combination of Developers, Testers and a Product Owner. As a team, you are responsible for the complete development and management cycle.
 + Together you work on (backend) microservices in the AWS Cloud, written in Java and Kotlin. Because you work with software that handles hundreds of requests per second (high performance), your work continues to be challenging.
 + Some of the things you are responsible for include:
o Designing and implementing Java/Kotlin microservices for S3 Passenger;
o Translating functionalities into software solutions and bridging the gap between desired functionality and technical solutions;
o At Sqills we focus on quality. This is reflected in the ownership our team members have for their own microservices, but also in the fact that we have extensive requirements for developing components.

 + Because our software offers the complete inventory, reservation and ticketing suite for our international customers, our focus on quality is especially important.
