Job description

Overview

LMAX is renowned for its high-performance, ultra-low latency (we measure in microseconds) exchange written in core Java. We constantly push technology further than most, especially in our greenfield projects, driving the financial industry in new directions.

If you want to work with great developer practices like fast feedback across all aspects of your work, a cooperative culture, and only shipping things when they\'re ready, while being at the heart of a thriving exchange with opportunities to learn about the finance industry, then LMAX is for you!

What you should expect

Developers are encouraged to constantly develop and learn new skills. Pair programming supports continual growth of knowledge and sharing of expertise, alongside regular team rotations ensuring everyone gains first-hand knowledge on all areas of our codebase. Friday afternoons are set aside as personal development time where you can explore a different coding language, research bleeding edge technologies, or play around with one of our environments. There is also regularly scheduled time to improve developer experience and reduce technical debt - directed by developers.

Our continuous integration and testing culture allows us to have confidence in our builds and develop quickly. We have over 30,000 acceptance tests running every 25 mins in our CI, alongside extensive test suites (performance, compatibility, migration, resilience). Continuous Delivery was pioneered at LMAX; due to pair programming and testing we don\'t do pull requests, we push directly to our monorepo with a "revert first, ask questions later" attitude.

What you\'ll be working with

Backend: Distributed, event-driven core Java (90% of the code-base), MySQL, Kafka
Frontend: Javascript, Vue.js
Deployment: Kubernetes, Nomad
Data analytics: Python & Jupyter notebooks, Parquet, Docker
Testing: JUnit, JMH, JCStress, Jenkins, Selenium, many in-house tools
OS: Linux (Fedora for development, Rocky in production)

The LMAX way is to use the right tool for the job, and this is a flavour of what you\'ll be working with. It isn\'t a list of requirements!

Requirements

Be passionate about software development. Bad code offends you!
Work in a dynamic environment enabled by fast feedback; the heart of our ethos
Pair programming in small teams of developers and testers (who also write code)
Share knowledge and learn from like-minded peers
Work across a variety of teams covering a wide range of technologies
Write performant, reliable, and well tested code - shipping only when it\'s ready
