Test Analyst (Future Finance)
Description:
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. Together, we will be driving the financial industry in new directions. Finance is going to be tokenised through the use of blockchain technologies. We want to be at the forefront of that wave, working with the institutions to build efficient, regulated and fair markets. We have gone from one developer to a small team over the last year and have already built a brand new trading solution, taking the best of centralised liquidity and decentralised security. It is live on public blockchains, we're not just prototyping. Our vision is a lot more than just this, so we need to grow into multiple teams as we shape the future of the financial landscape. Our roadmap is heavily developer driven, with CEO buy in, meaning you can substantially influence the direction of the project. Developers are encouraged to constantly develop and learn new skills. Pair programming supports continual growth of knowledge and sharing of expertise. Friday afternoons are set aside as personal development time where you can explore new languages, research bleeding edge technologies, or even come up with brand new projects pushing the boundaries of finance. There is regular time to improve developer experience and reduce technical debt. Our continuous integration and testing culture allows us to have confidence in our builds and develop quickly. We have already built a suite of new tools to maintain this mission with our dynamic tech stack. Continuous Delivery was pioneered at LMAX (one of the authors worked here while writing the book). 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.If you want to work in an environment that follows great developer practices such as 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 the finance revolution, then the LMAX future finance team is for you!
•Testing is core to what we do; the test analyst is the team’s test specialist (everyone can and will write tests) and you will direct where that effort goes.
What you should expect:
•We have a very mature testing setup so much of the work is expanding on what we already have but we’re always up for adding new types of tests.
•You will come up with the majority of test cases, functional and non-functional testing approaches and testing ideas as well as being able to write code to support them.
•Collaborative office environment with constant pairing and plenty of social activities.
•Work across the stack to solve a problem – you might be working with a performance critical component, integrating a new blockchain, or designing a greenfield cloud based system.
•Regular opportunities to learn and develop yourself with internal tech talks, ability to travel to conferences, and dedicated time for your personal development.
What you’ll be working with:
•Backend: Distributed, event-driven core Java 21 (80% of the code-base), MySQL, Kafka, Solidity (EVM Smart Contracts), Rust (Solana Smart Contracts)
•Frontend: Javascript, Vue.js
•Deployment: Kubernetes, AWS
•Testing: JUnit, Hardhat, Jenkins, Selenium, plus many, many in-house tools written in Java
•OS: Linux
The LMAX way is to use the right tool for the job so this is just a flavour of what you’ll be working with, and isn’t a list of requirements!

- Be passionate about testing - bad tests and bad code offend you!
- Be able to learn a domain and combine that with your knowledge of the code, architecture and testing to come up with test cases.
