We’re on the hunt for a brilliant mind—someone who can outthink our team, master our existing systems, and push our trading tech to new heights.
The Role: We’re seeking an exceptional C# .NET Developer to join our remote Asia team, working on our WinForms-based trading platform powered by SQL Server Compact CE. You’ll dive into our existing codebase, quickly learn its intricacies, and extend it with performant, multi-threaded code while adhering to established design patterns. You’ll collaborate closely, rotating design and coding duties daily, and use AI tools to turbocharge development. If you’re a creative genius who can outsmart us and thrive in complex systems, we want you.
What You’ll Do:
- Enhance and optimize WinForms UI for real-time trading, ensuring top-tier performance and responsiveness.
- Write highly performant, multi-threaded C# code, mastering thread-safe collections and avoiding pitfalls like deadlocks and race conditions.
- Manage data efficiently with SQL Server Compact CE for lean, local storage.
- Dive into existing systems, rapidly learning their architecture, workflows, and design patterns to extend and improve them.
- Co-create and review technical designs (e.g., UML, architecture docs), leading and contributing in a collaborative, rotating workflow.
- Leverage AI tools (e.g., GitHub Copilot, LLMs) to accelerate coding, debugging, and design innovation.
- Quickly adapt to new tools, APIs, or proprietary systems to tackle evolving challenges.
- Contribute to a trading platform with real-time market data, order execution, and financial algorithms.
Who You Are:
- A brilliant problem-solver with 3–7 years of C# .NET Framework experience, including deep WinForms expertise.
- A multi-threading expert, with proven experience handling deadlocks, race conditions, and thread-safe collections (e.g., ConcurrentDictionary).
- Skilled with SQL Server Compact CE or similar embedded databases (SQL Server knowledge a plus).
- A master of OOP (SOLID principles, design patterns) who writes elegant, scalable code.
- Adept at working with existing systems, quickly learning their structure, and following established design patterns to maintain consistency.
- Comfortable crafting and critiquing technical designs, with a disciplined design-before-coding mindset.
- Experienced using AI tools (e.g., Copilot, ChatGPT) to boost productivity and innovate workflows.
- A quick learner who thrives on complex challenges and adapts to new tech effortlessly.
- Ideally experienced in trading platforms or fintech (e.g., low-latency systems, order matching).
- Young (25–35), energetic, and driven to outthink and outshine your peers.
- Based in Asia, with reliable internet for remote work.
- A clear communicator who excels in collaborative, idea-driven teams.
Standout Qualities:
- You’ve mastered a complex legacy system and made it better, faster, or smarter.
- You’ve used AI to solve a tricky coding, design, or system integration problem in a way that surprised your team.
- You’ve led a project or design that redefined how your team approached a challenge.
- Bonus: Experience with .NET Core, APIs, or cloud (Azure/AWS), or open-source/personal projects that showcase your brilliance.
Why Join Us?
- Work-from-home flexibility with a passionate, Asia-based team.
- A collaborative culture where everyone designs, codes, and challenges each other to innovate.
- A high-impact trading platform that traders rely on daily.
- Freedom to use AI and cutting-edge tools to redefine development speed and quality.
- A team that celebrates your ability to outthink us and elevate our systems to the next level.
