Job Description:

We are seeking an experienced quantitative developer with 3+ years working in the HFT industry, having seen and built successful low latency trading systems.

In this role, your responsibility is to design and improve our trading stack end to end to make the firm’s trading strategies more competitive and profitable.

This is an onsite role and as such permanent remote work is not an option.

Responsibilities

Your main responsibilities are developing and rapidly evolving our main software components:

• Develop low latency trading engine and strategy runtime.
• Develop and maintain exchange API connectivity and robust exchange connectors.
• Full automation around deployment and monitoring of a 24/7 trading system.
• Continuous profiling of trading system and strategy latency.
• Understand and reverse engineer exchange architectures.

You will be part of a small development team that shares the responsibility of the whole trading stack. As you own the code, deployment, and all tooling, you can rapidly and safely iterate on changes to the trading software. As a result, we deploy many times a day.

Developers collaborate directly with traders and researchers, allowing for immediate reaction to market changes and fast iteration of live trading engines.

Skills

You must be a self-starter and self-learner excited to compete in the markets. Over your career, you have picked up the following skills:

• Experience writing low latency Java/C++ applications and architectures. HFT industry preferred but telecom and gaming industry experience also welcome.
• Ability to get the best performance out of the application and networking stack of on-premise and cloud environment.
• Ability to benchmark, profile, and trace full applications on Linux.
• Ability to find and resolve latency and throughput bottlenecks.
• Excited to pick up new skills to solve difficult problems (examples: eBPF, XDP, Intel PT).

While we are language agnostic, our current trading stack is mostly written in Java. Some technologies we use: Aeron, SBE, Java 20+.

Benefits

• Discretionary bonus scheme.
• Private health insurance.
• Free Friday lunches, drinks, and snacks.
• Conference budget.
• Central London office.

If the above job description excites you, please submit your CV together with a brief cover letter that clearly outlines the reason why you apply and what makes you a great fit for the role.
