Hackajob is collaborating with LMAX Group to connect them with exceptional tech professionals for this role.
About the Role
LMAX is renowned for its high‑performance, ultra‑low latency exchange written in core Java, measuring microseconds. We constantly push technology further than most, especially in our greenfield projects, driving the financial industry in new directions. 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 minutes 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.
