Job Description

Trading Systems Architect

Central London - 5 days onsite

Permanent Employment

Nord Group is partnered with a privately owned Investment Bank based in London, who are looking for a Trading Systems Architect to join a multi-year Fidessa migration programme. The project aims to revamp a significant part of their equity trading technology stack. This Greenfield project involves designing and implementing new trading systems such as risk engines, market/reference data, and trading gateways, while modernising their proprietary OMS.

Responsibilities:

You will play a key role in building a next-generation Cash Equity and Electronic Execution Platform. This includes ensuring high availability for global equity market trading, developing custom trading workflows for diverse client needs across trading desks, and designing scalable systems that respond to market events like interest rate decisions and breaking news. Collaboration with other engineering teams and project members is essential.

Key requirements:

• Minimum 7-10 years of experience with expertise in modern software design, architecture patterns, and performance measurement (capacity, throughput, latency).
• Balance between a commercial mindset, technical knowledge, and effective communication with traders and front-office stakeholders.
• Operate confidently at a technical architect level, demonstrating expert Java skills (high-performance, low-latency, microservices) and experience in real-time trading.
• Comprehensive knowledge of trading systems, including integration with reference and market data systems, especially within equity trading using OMS or EMS.
• Solid understanding of how Fidessa works from both functional and technical perspectives.
• Good knowledge of microservice architectures and container technologies (e.g., Kubernetes).
• Ability to test your own code effectively (automated, unit, UAT, and some manual testing), as there is no dedicated QA or testing team.
