About Us
MarketAxess is on a journey to digitally transform one of the world’s largest financial markets, enabling the shift from analog, phone-based trading to a fully electronic marketplace. Why does this matter? Because our platform makes trading fixed-income more accessible, ultimately improving transparency, efficiency, and competition in the marketplace. Changing the way an established industry transacts is no easy feat. There will be twists and turns, because no one’s ever done this before. But now, more than 2,000 clients around the world rely on our solutions, and that number is only expected to grow in the years ahead. We know where we’re going. How we get there is up to us. Join us and help Take Us There.
The Role
We are seeking a Software Engineer to join our Reference Data team and help modernize how we manage and deliver critical data for Fixed Income trading. This role focuses on building robust data engineering solutions, implementing Master Data Management and Golden Source strategies, tracking data lineage, and enabling efficient data wrangling and analysis.
