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 an engineer for the EU Customer Integration (CI) group. The CI group partners with broker‑dealers and institutional clients to integrate their systems with the MarketAxess Fixed Income trading platform through our suite of Application Programming Interfaces (APIs), covering front‑office, mid‑office, and back‑office workflows. As the firm advances its strategic focus on an API‑first architecture, this role directly supports that vision by enabling clients to adopt standardized, scalable, and resilient API‑driven integrations. The CI group also leads the implementation of our market data products/feeds and our Post‑Trade APIs, ensuring alignment with the company’s broader technology strategy and long‑term vision.
