We operate a specialized platform that connects asset managers with liquidity providers to streamline workflows and improve pricing for derivatives, structured products, and ETFs.

- Proven ability to design and implement complex, distributed software solutions.
- Proficiency in writing advanced SQL queries for SQL Server or Oracle.
- Experience with Test Driven Development and implementing unit and integration tests using tools like Jest.
- A collaborative mindset, as you will be working closely with multi-disciplinary teams across both Virtu and MarketAxess.
- While not required, familiarity with React.js, TypeScript, HTML, and CSS is considered a plus.
