Location: London

Working Pattern: Hybrid, 3 days per week in the office

Salary: Up to £200,000 base + exceptional bonus (Total Compensation up to £350,000)

Join one of the largest growth programmes in Electronic Trading Technology

A leading global investment bank is making a significant investment in its London Electronic Trading engineering team, expanding ownership of key trading platforms from the US into Europe.

This is an opportunity to join a business that is actively building rather than maintaining, with multiple senior hires planned over the next 12 months. You'll work alongside experienced engineers developing the next generation of low latency electronic trading systems supporting global markets.

If you enjoy solving complex engineering problems where performance, reliability and speed matter, this is the type of environment you'll thrive in.

The Opportunity

You will become part of a highly experienced engineering team responsible for developing and enhancing mission critical electronic trading platforms across multiple asset classes.

Working closely with traders, quantitative teams and business stakeholders, you'll build software that directly impacts trading performance and execution quality.

Projects include:

• Designing and building low latency Java applications
• Developing electronic trading and execution platforms
• Building pricing and market data infrastructure
• Improving platform performance, scalability and resilience
• Enhancing execution algorithms and trading workflows
• Working on highly distributed, performance critical systems

What They're Looking For

We're looking for experienced Java engineers who have worked within high performance front office technology environments.

You will likely have experience in several of the following:

• Core Java development
• Electronic Trading platforms
• Low latency systems
• Pricing engines
• Execution platforms
• Market Data
• Multithreaded and concurrent programming
• Distributed systems
• Performance optimisation

Experience within Rates or Equities trading technology would be particularly valuable, although candidates from other electronic trading asset classes will also be considered.

Modern Engineering

The engineering organisation actively embraces modern software development practices.

Developers are encouraged to leverage AI assisted development tools such as:

• GitHub Copilot
• Cursor

You will be expected to understand how AI can improve software engineering productivity while maintaining strong engineering fundamentals.

McGregor Boyall is an equal opportunity employer and do not discriminate on any grounds.
