Job description

Quantitative Developer @ Tier 1 Investment Firm

KDB+, q, Python, Equities, Electronic Trading, Execution, Quantitative Development, Linux

My client is a leading global investment firm with a sophisticated technology and quantitative environment supporting its equities business.

The firm is seeking a Quantitative Developer in Hong Kong to join a team responsible for building and enhancing quantitative technology across equity execution, liquidity and trading.

This is a highly hands-on role combining quantitative development, technology and financial markets, with the opportunity to work closely with quantitative researchers and traders on large-scale equity trading flows.

Responsibilities

• Develop quantitative applications primarily using q/kdb+ and Python
• Design and optimise computationally intensive quantitative models
• Build systems capable of processing large volumes of real-time and streaming market data
• Develop applications supporting equity execution, liquidity and trading workflows
• Work across standalone applications and integrate with wider trading and technology platforms
• Collaborate closely with quantitative researchers, traders and developers
• Contribute to system design, technical specifications and APIs
• Take ownership of solutions from initial design through development and production

Your experience

• Strong development experience with KDB+/q and Python
• Experience within a development-intensive role in financial services
• Strong understanding of Unix/Linux
• Experience working with large datasets, real-time data or performance-sensitive applications
• Strong programming and computer science fundamentals
• Exposure to equities or electronic trading would be highly advantageous
• Experience across execution, algorithms, TCA, liquidity, Delta One or synthetic products would be beneficial but is not essential
• Strong communication skills and ability to work closely with both technical and business stakeholders
• Ability to learn quickly, take ownership and operate effectively in a fast-moving environment

Candidates do not need to come from a traditional Quant Developer background. Strong KDB+/Python developers from banking or equities technology environments who are looking to move closer to quantitative development and trading are encouraged to apply.

The opportunity

This is an opportunity to join a leading global investment firm, working on quantitative technology that directly supports large-scale equity trading and execution.

You will work closely with quantitative researchers and traders, giving you strong visibility into how your technology is used and the opportunity to contribute to problems across execution, liquidity and quantitative modelling.

The team offers significant technical ownership and variety. Rather than being restricted to a narrowly defined development role, you will have the opportunity to work across different problems and gain broader exposure to the intersection of technology, quantitative research and trading.

For developers looking to move closer to the business and trading decision-making, while remaining highly technical, this provides a strong platform to broaden both your engineering and financial markets expertise.

The firm offers highly competitive compensation, significant individual ownership and a collaborative, fast-moving environment where engineers can have a meaningful impact.
