Quantitative Developer HFT

We are seeking a quantitative developer to join our team.

As quantitative developer your aim is to improve our trading stack in any way to make the firm's trading strategies more competitive and profitable. In a high-frequency trading environment this often means to improve the end to end latency of our trading platform or to increase the scalability and precision of execution of our trading strategies.

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 market data distribution platform (internal binary protocols)
• 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

Skill

You must be a self-starter and self-learner excited to compete in the markets. Over your career you have picked up some 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 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)

The ideal profile has experience in the HFT industry combining software development and networking skills (TCP / UDP / multicast / WebSocket / HTTP).

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