Job description

Software Engineer Tooling - HFT - Hong Kong

Build innovative trading, analysis, and data tools that empower traders and researchers to scale strategies, uncover opportunities, manage risk, and make faster, better-informed decisions.

What You’ll Do:

• Build intuitive tools that help traders orchestrate and scale strategies across a broad product range.
• Develop high-performance infrastructure that makes large datasets easier to explore, analyse, and understand.
• Create solutions for trade analysis, risk modelling, and identifying emerging trading opportunities.
• Work across the full technology stack, using Python, Java, React, SQL, and other tools where they deliver the best outcome.
• Take ideas from early experimentation through to robust, scalable production solutions.
• Work closely with traders, researchers, and business stakeholders to understand challenges and turn them into effective technology solutions.

Your responsibilities will include:

• Partnering directly with end users to understand their workflows, challenges, and underlying needs.
• Translating ambiguous problems into practical technical solutions.
• Rapidly prototyping and testing new ideas to determine what creates genuine value.
• Scaling successful solutions into reliable, high-performing systems.
• Analysing large volumes of trading and market data to uncover useful insights.
• Supporting strategy development, trading analysis, risk assessment, and operational decision-making.
• Choosing the most appropriate technology for each problem rather than being tied to a particular language or framework.
• Continuously improving tools based on fast feedback and close collaboration with stakeholders.

Why Join Us:

This is an opportunity to work at the intersection oftrading, data, technology, and research , where your work can have a direct impact on how strategies are developed, analysed, and scaled.

You’ll work in an environment built around short feedback loops, close collaboration, experimentation, and meaningful ownership. The problems are varied, the technology landscape is broad, and there is plenty of scope to shape what gets built rather than simply implementing a predefined brief.

About You:

• You enjoy solving open-ended problems where defining the right solution is part of the challenge.
• You are comfortable moving between programming languages and technologies depending on the problem.
• You care more about choosing the right tool than defending a favorite technology.
• You communicate confidently with technical and non-technical stakeholders.
• You are skilled at uncovering what people actually need, beyond the initial request.
• You enjoy experimentation and are comfortable testing ideas quickly.
• You know when to develop an idea further and when to move on from something that hasn’t delivered value.
• You thrive in fast-moving, collaborative environments where technology directly supports business outcomes.

If you’re excited by challenging problems, rapid experimentation, and building technology that directly changes how trading and research are done, this is a chance to turn ambitious ideas into tools that make a real difference.
