We're Celonis, the global leader in Process Mining technology and one of the world's fastest-growing SaaS firms. We believe there is a massive opportunity to unlock productivity by placing data and intelligence at the core of business processes - and for that, we need you to join us.

The Team:

You will be part of the Core Mining Engine team. The Core Mining Engine enables our customers to interactively process mine enterprise-sized data sets. To achieve that goal we developed our own analytical database. In order to handle the strong growth of our customer base and their demands we heavily invest in the scalability of the Core Mining Engine.

The Role:

As a member of the Core Mining Engine team, you will work on our analytical database which is built on a microservice architecture, optimised to process large amounts of data. You will address scaling problems, increasing robustness while maintaining cost efficiency and integrating the Core Mining Engine with new technologies like Apache Kafka. 

The work you’ll do:

  • Implementing features in existing or newly created microservices
  • Take ownership of features from design to operation
  • Collaborate with various teams and coworkers to cope with rapidly increasing system workload
  • Identify and eliminate bottlenecks in our current system

The qualifications you need:

  • You have experience with writing scalable, reliable, and testable software
  • You are fluent in Java. Python or C++ are a plus
  • You have experience with developing data-intensive and performance-critical systems
  • You know how to analyse complex systems
  • You have solid knowledge of data structures / algorithms
  • You have solid knowledge about asynchronous / concurrent programming and have worked with the low-level building blocks of synchronization like semaphores, read-write locks, mutexes etc.
  • You are familiar with Spring

What Celonis can offer you:

  • The unique opportunity to work with industry-leading process mining technology
  • Investment in your personal growth and skill development (clear career paths, internal mobility opportunities, L&D platform, mentorships, and more)
  • Great compensation and benefits packages (equity (restricted stock units), life insurance, time off, generous leave for new parents from day one, and more)
  • Physical and mental well-being support (subsidized gym membership, access to counseling, virtual events on well-being topics, and more)
  • A global and growing team of Celonauts from diverse backgrounds to learn from and work with
  • An open-minded culture with innovative, autonomous teams
  • Business Resource Groups to help you feel connected, valued and seen (Black@Celonis, Women@Celonis, Parents@Celonis, Pride@Celonis, Resilience@Celonis, and more)
  • A clear set of company values that guide everything we do: Live for Customer Value, The Best Team Wins, We Own It, and Earth Is Our Future
