We host hackathons to explore new tech, ideas and tools, and our internal developer forums are open spaces for discussing architecture, new technologies, and tough engineering challenges. Whether building or learning, there's always room to experiment and grow. 

Let's dive into your key responsibilities. You will: 

• Work in a dynamic and international environment with experienced and skilled colleagues 

• Design, develop, and maintain efficient, reusable, and reliable code using engineering best practices and design patterns. 

• Drive a culture of “you build it - you own it” - mentality 

• Identify and act on areas for your own personal development 

• Mentor and coach co-workers on topics that you master. 

The need-to-have skills 

• Proven ability to thrive in environments that value adaptability, shared ownership, and continuous improvement 

• Experience working with .NET and C#

• Good communication skills and fluency in business English (spoken and written) 

• Open towards and able to quickly learn new technologies 

• Ability to troubleshoot problems, debug and suggest solutions 

• A pragmatic and responsible approach to GenAI, understanding its limitations and risks, and actively establishing guardrails (e.g. reviews, testing, and policies) to ensure safe, compliant, and scalable use in production environments. 

The nice-to-have skills 

• Experience working with AWS Infrastructure or other cloud providers, especially containerization and serverless computing.
