Are you looking for a job with plenty of ways to challenge and improve yourself? Do you value working for a company that supports your professional development and offers working on a mission-critical SaaS suite? That, and more, is what we offer you. We are looking for Java Developers who want to work with the latest techniques and want to continue to challenge themselves. Siemens is operating a Software Development Center in Spain, Valencia targeting Intelligent Solutions for the future of Mobility. We want YOU to join our team Our approach: This position is for one of our DevOps team. DevOps teams develop and maintain microservices that are part of S3 Passenger, our ticket and seat-reservation backend system. Some microservices are high-performing and others need extra security because they handle payment data for instance. But the team's responsibility does not stop there. They also develop other applications in Java and are in charge of our own CI/CD development pipelines and other tooling that help support our daily responsibilities. In addition to Java, the team may also code in Kotlin and Go. At our teams have the freedom to spend time exploring new technologies that they can use to improve the performance of their microservices. We strive to do so continuously. Sqills uses Terraform, Kubernetes, and a number of other tools to manage the infrastructure (Infrastructure as Code). Our infrastructure is a combination of traditional services, AWS Lambda, and managed services such as DynamoDB, RDS, AmazonMQ, CloudWatch, and ELB. We monitor services in production using OpenTelemetry, New Relic, and PagerDuty. We also have a custom-built frontend that integrates these monitoring tools and visualises fully distributed traces to help us analyse errors in our microservice landscape. Secure development, architecture, performance, and resiliency are the cornerstones common to the different teams. This ensures that our software will continue to meet and exceed expectations in the future. We are always looking to improve our code, with an emphasis on performance, reliability, and quality. We share all workloads within the team and try to make the best use of everyone's strengths. We love to share our knowledge and help each other achieve our goals. Your key responsibilities: * Collaborating on software used to find and book seats for major international travel brands like Eurostar, Renfe, and SNCF. * Optimising the processing of asynchronous requests for high-availability, high-performance components or to put extra effort in securing the processes as much as possible. ## Related Videos - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Navigating the Corporate Jungle: Life as a Developer in a large Company](https://www.wearedevelopers.com/videos/621-navigating-the-corporate-jungle-life-as-a-developer-in-a-large-company) - [Migrating half a million users to a new payment service provider](https://www.wearedevelopers.com/videos/730-migrating-half-a-million-users-to-a-new-payment-service-provider) - [DevOps Maturity Check – a way to balance autonomy and alignment](https://www.wearedevelopers.com/videos/58-devops-maturity-check-a-way-to-balance-autonomy-and-alignment) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Spanish Business Culture and Etiquette](https://www.wearedevelopers.com/magazine/353-spanish-business-culture-and-etiquette) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe) - [Top-Paying Tech Jobs (with Salaries)](https://www.wearedevelopers.com/magazine/372-top-paying-tech-jobs-with-salaries) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs)
