Senior Software Engineer (Rust / C#) | Build the Future of Global Trading

Imagine a place where technology isn't just a department—it's the entire company. We are a private, global trading firm with core technology hubs in Hong Kong and London, operating at the absolute cutting edge of financial markets. We aren't a bank or a traditional fund; we are a collective of brilliant and driven engineers, researchers, and traders who build everything from the ground up.

Our competitive edge is our code. We engineer ultra-low-latency, high-throughput systems that trade across global markets 24/7. We've built a culture where intellectual curiosity thrives, the best ideas win, and a passion for solving incredibly complex problems is what gets us out of bed in the morning. Our team is young, international, and built on a foundation of mutual respect and a shared obsession with technical excellence.

The Opportunity

This isn't just another coding job. It's a chance to join an elite team that builds the high-performance systems powering our global trading operations. We're searching for a Senior Developer who is obsessed with elegant solutions, clean code, and pushing the boundaries of what's possible with technology.

You'll be working in a 100% hands-on role where you own your projects from end-to-end. This is a position with a direct and achievable path to leadership; perform well, and you could soon be building and leading your own team of engineers.

What You Will Do

• Architect, build, and enhance the critical applications and user interfaces that form the backbone of our trading infrastructure, using modern Rust and .NET.
• Thrive in a highly collaborative, agile environment, working shoulder-to-shoulder with a global team of world-class engineers in Hong Kong and London.
• Spearhead research into emerging technologies and industry best practices, driving their integration to keep our systems ahead of the curve.
• Own the reliability, scalability, and performance of your code in a 24/7 production environment.
• Mentor and elevate junior engineers, fostering a culture of technical excellence and continuous knowledge sharing.

What You Will Need

• You have 5+ years of professional software development experience, with a solid grounding in a Linux environment.
• You hold a university degree in Computer Science, Software Engineering, or a related discipline.
• You craft beautiful, maintainable code. While we're heavily invested in Rust and C#, your deep expertise in any modern object-oriented language (Java, C++, etc.) is highly valued. If you have the right engineering fundamentals, we'll help you master Rust.
• The world of financial markets, low-latency systems, and blockchain technology genuinely excites you.
• You take immense pride in your work, owning every aspect of your deliverables from design to deployment.
• You have a deep-seated passion for dissecting complex problems and engineering elegant, efficient solutions.
• You're a natural mentor, finding satisfaction in helping your colleagues grow.
• Bonus points for experience with multithreading, high-throughput/low-latency system design, or modern web protocols (e.g., WebSocket, RESTful APIs).

Why You'll Love Working Here

• We've built a home for engineers who love to code. We understand that top talent deserves the best environment, compensation, and culture.
• The Culture: We've cultivated a unique atmosphere that respects deep focus and individual contribution (perfect for introverts!) while also celebrating our successes together. Expect engaging team dinners, happy hours, and a genuinely friendly social fabric where you can connect with like-minded colleagues.
• The Rewards: We offer a highly competitive compensation package, including a strong base salary and a significant performance-based discretionary bonus.

World-Class Benefits

• Full visa sponsorship and relocation support for exceptional international candidates.

• Generous Leave: 20 days of annual leave, plus paid parental, family care, and other life-event leaves.
• A vibrant office life with regular birthday parties, annual dinners, happy hours, and team-building events.

If you are a builder at heart and want to see your code make a direct impact in a fast-paced, intellectually stimulating environment, we would love to hear from you.
