• 5+ years of professional software engineering experience.
• Strong backend experience with C# / .NET (recent versions).
• Experience building and consuming REST APIs.
• Frontend experience with Angular
• Hands-on experience with Azure, including setting up cloud components.
• Comfortable working on greenfield projects and taking ownership.

Location: Hybrid, 3 days in the Amsterdam office and 2 days remote

Work abroad: Up to 60 days every 6 months

Relocation: Supported

Hiring process

The process consists of three stages overall, combining practical and conversational elements. It is designed to assess real-world engineering ability, technical depth, and team fit rather than theoretical knowledge.

Due to the expected volume of applications, we are unfortunately unable to provide extensive individual feedback during the CV screening stage.

If you are a Senior Frontend Engineer looking to work on serious, real-time trading systems, this is one of the strongest frontend opportunities in the market.
