The Team:

Celonis USA is the fastest-growing division of one of the world’s fastest-growing companies. 

Come join us on the ground floor on a team led by experienced ex-FAANG coworkers dedicated to developing state-of-the-art technology for Celonis products. The team creates foundational solutions such as a mining engine that enables our customers to interactively execute process mining over enterprise-sized data sets, as well as innovative object-centric modeling tools that empower users to perform process-oriented business analysis in a natural and powerful way.

Join us if you want to grow in your engineering knowledge, and your career and leave your mark on a rapidly growing company.

The Role:

We are looking for senior backend developers who enjoy building systems with the capability to manage big data.

With your general knowledge of working with modern C++, coupled with experience in developing high-performance large-scale data processing systems, you will create new, innovative algorithms and operators for our query engine.

The work you’ll do:

  • Deal with issues from logical representations of the execution plan to efficient resource management, all the way down to highly parallel vectorized execution
  • Design and implement critical high-performance systems to handle the ever-growing request rate on our database
  • Evangelize best practices in database usage and end-to-end architecture
  • Set an example for and mentor and grow your teammates
  • Recognize and take action to improve the developer work environment
  • Write clean, understandable, and testable code
  • Provide feedback on the designs and code of peers
  • Manage individual project priorities, deadlines, and deliverables
  • Document development procedures, concepts and knowledge
  • Build, launch, and maintain features in production
  • Help define a fun and inclusive engineering culture

The qualifications you need:

  • BS in Computer science; Masters or Ph.D. preferred
  • 5+ years of hands-on software engineering experience
  • Significant background in database internals or building core components (query optimization, query execution, storage engines, transaction processing) for large-scale data processing systems (e.g., Starrocks, ClickHouse, etc)
  • Experienced in programming with C++ (17)
  • Have an analytical mind and a good understanding of complex data structures and algorithms in data management
  • Have a curiosity about how things work and a desire to improve them
