Contribute to the continued development and improvement of the firm's technology platform

Your experience

Excellent understanding of data structures, algorithms and computer science fundamentals

Strong knowledge of Linux/Unix

Good understanding of systems programming, memory management and networking

Experience developing large-scale, distributed or performance-sensitive systems

The opportunity

This is an opportunity to join a highly technical, engineering-driven financial firm in Hong Kong, working on sophisticated, performance-critical systems at the heart of the business.

You will work alongside experienced engineers on challenging C++ problems, with high visibility, genuine ownership and the opportunity to influence how systems are designed and developed. Engineers are encouraged to take initiative, contribute ideas and see their work through from initial design to production.

The role offers close interaction with the business and direct exposure to financial markets, allowing you to see the impact of the technology you build rather than operating several steps removed from its end users.

For C++ developers looking for challenging technical work, greater autonomy and a more direct connection between engineering and the business, this is an opportunity to make a meaningful contribution within a collaborative international environment.

The firm offers highly competitive compensation, strong career development and an environment where good engineering and individual contribution are genuinely valued.
