Job Description:

Your mission at SimScale is, together with our developers, to build and continuously improve a robust and scalable infrastructure for running our development and production services.

This means staying on top of changes in the cloud computing world, but also technologies and concepts like micro-services and containers, to help foresee the architecture and infrastructure SimScale will need tomorrow.

You ensure that our developers can efficiently and safely test their changes and put them in production, with infrastructure in place for techniques like canary or gradual releases, or blue-green deployment, and logging and metrics to ensure proper behavior of our complex service architecture. Depending on skill set and workload, you also help to adapt existing or new components to infrastructure, e.g., migrating a component to a message-based architecture.

You will be working at the intersection of a complex service-oriented web application and the world of Computer-Aided-Engineering, which brings interesting challenges of its own, such as the combination of significant computations resulting in large amounts of data, while at the same time empowering a thriving community of users to collaborate and to share simulation projects.

  • At least 5 years of professional experience in software development focusing on Java
  • At least 5 years of extensive experience in developing RESTful cloud services and/or microservices
  • Strong sense of code quality: you follow design patterns and the principles of clean code
  • Strong ownership-attitude: you want to deliver and maintain solid parts of the product
  • Data-driven mindset: you act on the insights from errors and usage data
  • Experience with a cloud provider, especially AWS
  • Sensibility towards IT security and the topic of concurrency

  • Being involved in open source projects
  • Very solid skills in Linux or comparable OS
