Nice to Have:  

• Experience programming in Scala  

• Experience working with very large datasets (projects, coursework, or research) 

• Familiarity with tools such as Spark or distributed systems  

• A PhD in a relevant field  

What we offer  

• A chance to join a top-tier engineering team in Copenhagen with a strong academic and technical foundation  

• Close collaboration with global teams across the US and Europe  

• A learning-focused environment where junior talent is mentored and developed  

• Exposure to real-world, large-scale machine learning systems  

• A culture of autonomy, ownership, and collaboration  
• Flexible working conditions and modern office environment
