Core focus is hands-on low-latency Java development.
Occupation involves exposure to low-latency trading systems in banks or financial institutions.
Key Responsibilities & Expectations
- Experience as a strong Java developer (specialising in low-level / core Java).
- Background in building or contributing to low-latency systems.
- Typically 10+ years overall engineering experience; ideally ~4–5 years in low-latency systems (flexibility if strong elsewhere).
- Exposure to systems handling ultra-high throughput (e.g. billions of events per day).
- Ability to design and implement components within a Java-based system.
- Comfortable working in finance/trading environments (FX preferred).
- Preferred: Experience with FX / electronic trading systems (spot, forwards, swaps, execution systems).
- Acceptable: Some familiarity with rates or equities environments.
- Less relevant (not ideal): Crypto experience due to latency expectations.

What the Role Involves
- Breaking down epics into Jira tasks, estimating and planning own work, and executing autonomously.
- Strong hands-on coding role (not architecture-focused).
Eligibility Criteria
The role does not suit:
- Pure microservices / REST-only backend developers.
- Candidates with misleading CVs claiming low-latency experience without verifiable credentials.
- Front-end developers (React/TypeScript not a focus of this role).
- Very junior engineers or those with only brief exposure to low-latency systems.
Additional Notes
- Due to high application volume, only suitable candidates will be contacted for interviews.
