# Low Latency Java Developer

- **Company:** McGregor Boyall Associates Ltd.
- **Location:** London, UK
- **Experience:** Experienced
- **Contract:** Permanent contract
- **Skills:** Java (Programming Language), Algorithmic Trading, C++ (Programming Language), Computer Engineering, Relational Databases, Python (Programming Language), Low Latency
- **Published:** September 3, 2026
- **Apply:** https://www.careerboard.com/pt/en/find-jobs-in-United-Kingdom/-A1108F74B948EA213A/

## About the Role

* Strong experience in Java, Go or C++ building distributed, scalable systems
 * Roughly 2 - 7 years shipping and maintaining highly optimised code
 * Python, high-concurrency systems, low-latency or high-transaction environments, relational databases - all useful, none essential
 * CS, Computer Engineering or equivalent background
 * Communication skills that hold up in technical debate

Worth knowing: flat hierarchy, meritocratic, fast-paced. No finance knowledge expected - they teach it. 26 days annual leave, private health/dental/optical, income protection, pension, gym subsidy, catered lunch daily.

This suits an engineer who wants ownership early, likes performance-critical problems, and would rather learn the market from the inside than sit in a large corporate engineering function.
