Graduate Java Developer, 2026

As a Graduate Analyst, you'll join a team that builds high-performance, ultra-low latency systems at the heart of a thriving exchange and an institutional-grade digital asset custodian. You'll begin with important initiatives-such as enhancing CI/CD pipelines, building internal tools, or open-sourcing utilities-designed for your learning and development, and to help you build confidence and technical depth. These projects are essential components of our engineering ecosystem and offer real opportunities to make a difference.

You'll be supported by a dedicated mentor and surrounded by skilled professionals. As you grow, depending on your interests and available opportunities, you may have the chance to rotate into other areas of our Technology department, explore different technologies, and take on increasingly complex challenges.

This is more than a graduate role-it's a launchpad into a high-impact engineering career.

What You Can Expect

• A high degree of ownership over your projects, with strong mentorship and guidance.
• An on-the-job learning environment where you'll gain practical experience across multiple areas.
• Exposure to industry-leading developer practices, such as continuous integration and continuous delivery.
• Opportunities for personal development, including time to explore new technologies, improve developer experience, and reduce technical debt.
• A collaborative culture that values knowledge sharing and fast feedback.

What You May Be Working With

• Backend: Core Java (90% of the codebase), MySQL, Kafka
• Data Analytics: Python, Jupyter Notebooks, Parquet, Docker
• Testing: JUnit, JMH, JCStress, Selenium, and in-house tools
• OS: Linux (Ubuntu/Fedora for development, various in production, Rocky/CentOS, Amazon Linux)

You may work with any of these technologies-or others-depending on the project requirements. Don't worry if you don't know all the tools.

Why Join Us?

At LMAX, we're known for building high-performance, ultra-low latency systems (we measure in microseconds) and constantly pushing technology further than most, especially in greenfield projects that drive the financial industry forward.

Our engineering culture promotes collaboration and continuous learning, with practices such as pair programming and regular team rotations to broaden experience across the codebase. Developers also benefit from dedicated time for personal development, exploring bleeding-edge technologies or experimenting in our environments, alongside separate sessions focused on improving developer experience and reducing technical debt.

We take continuous integration, delivery, and testing seriously, running over 30,000 acceptance tests every 25 minutes and maintaining extensive performance and resilience suites. Continuous Delivery was pioneered here-one of the authors of the book on the subject worked at LMAX while writing it. Our streamlined workflow, pushing directly to a monorepo with a "revert first, ask questions later" approach, reflects our commitment to speed and quality.

As a Graduate Analyst, you'll start with smaller, focused projects under the guidance of a mentor, with the opportunity to grow into this environment. If you're looking for great developer practices, fast feedback, and a cooperative culture at the heart of a thriving exchange and digital asset custodian, then LMAX is for you!
