We share one common goal: enhancing the passenger experience with our combined power for the future of Mobility.

As an experienced Java Developer, you have a wide range of opportunities. 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.
• Improving development pipelines or helping analyse new feature requests.
• Continuously refactoring code to improve its quality and performance.

Are you a match?

• Do you have what it takes to work on a mission critical Java microservice?
• Are you passionate about refactoring code and making it shine?
• Do you enjoy working in a team that welcomes new perspectives and is eager to hear your ideas?
• Do you get a warm feeling when thinking about learning a new programming language or technology?
• Are you proficient in Spanish and English and possess strong communication skills?
• Do you want to have a seriously good time at doing all of this?
• Do you thrive in a “work hard and play hard” culture with team outings, company events, VrijMiBo, BBL (Brown Bag Lunch), FFF (Fat Frying Fridays) and more abbreviations you don’t understand yet?

We recognise that building a diverse workforce is essential to the success of our business, therefore we encourage applications from a diverse talent pool.

We welcome the opportunity to discuss flexibility requirements with our applicants to encourage agile working and innovation. Flexibility is our main benefit. We combine remote and presence work because work-life balance and wellbeing are essential for our teams. We are convinced that stay at home allow us to focus on activities that need more time for concentration and being at the office enhance our creativity collaborating and learning from others.
