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
MarketAxess – a leading electronic trading platform in the US, European, and Asian markets – is hiring for a UK-based Software Engineering Apprentice to join the team supporting and developing our RFQ-hub platform.
This is an entry-level opportunity designed for someone who thrives in a fast-moving environment, enjoys problem-solving, and wants to build a career in software engineering. You’ll learn from experienced engineers while contributing to real production services, with a structured training program and protected time for off-the-job learning.
The training program is expected to run for approximately 12 -18 months (subject to confirmation at offer stage), with regular learning activities throughout.

- Support client onboarding and certification activities, helping improve documentation and automation to make integrations smoother over time.
