ROLE OVERVIEW  

As a Senior .NET Engineer, you will build and support data-intensive systems that power solutions for professional sports. You’ll play a key role in shaping how data and technology drive performance insights across multiple sports.  

You will take technical ownership of our individual sport products, including our existing Darts offering, while also contributing to the evolution of our multi-sport platform supporting sports such as basketball, handball, and hockey. The role focuses on backend API development and end-to-end system ownership, working across complex, distributed systems with an emphasis on scalability, performance, and security. This is a hands-on senior engineering role within an international environment that values collaboration, accountability, and technical excellence. 

THE CHALLENGE: 

• Creating flexible systems that work across a variety of sports 
• Take ownership in shaping and delivering key features and products whilst working alongside the Product team 
• Write high-quality, maintainable, and testable code, increasing unit test coverage and confidence 
• Lead the development of software services optimized for deployment into AWS 
• Collaborate with and become integral to a cross-functional team of Product, Design, Engineering, and System Administration 
• Meet regularly with Security members to review service needs and improvements 

REQUIREMENTS

• Strong experience with SQL-based databases such as SQL Server, MySQL, or similar relational databases 
• Experience with designing, consuming and writing APIs

ABOUT YOU  
 
You’re a developer who thrives on solving complex challenges and delivering clean, scalable solutions. You bring deep expertise in C# and the latest .NET technologies, and you approach architecture with clarity and purpose — using design patterns not just as tools, but as guiding principles.  

You’ve spent 5–10 years honing your craft in software engineering. You take ownership of your work, lead yourself with confidence, and stay focused even when working independently.  

You’re a natural problem-solver who enjoys fixing things, not just building them. You communicate clearly, collaborate effectively, and bring a sense of responsibility to everything you do.  

You’re curious, self-motivated, and always learning — whether it’s new tech, better practices, or the people around you. You’re not afraid to step outside your comfort zone and embrace growth opportunities.
