Senior Software Engineer C#/.Net

Are you a C#/.NET developer who thrives in fast-paced, high-intellect environments? I'm hiring for a tight-knit, high-performing software team working at the intersection of sports analytics, automated trading, and modern software development. You'll help drive greenfield product development from the ground up, with full autonomy and no bureaucracy.

• Greenfield projects - make architectural decisions and ship fast

• No prior trading or sports market experience required - just strong engineering skills

• C# / .NET (Latest versions)

• SQL Server, plus experience with Oracle or equivalent

• Bonus: exposure to JavaScript/React, multi-threading, or network programming (TCP/UDP)

• Build and maintain internal tooling that powers automated sports market trading

• Contribute to greenfield systems, from design through to production

• Collaborate with researchers and devs on experimentation and rapid iteration

• Write high-quality, scalable, performant code in a flat, agile structure
