- Write highly performant, multi-threaded C# code, handling thread-safe collections and avoiding pitfalls like deadlocks and race conditions.
- Manage data efficiently using SQL Server Compact CE for lean, local storage.
- Learn and extend existing systems, gaining a deep understanding of their architecture, workflows, and design patterns.
- Collaborate on technical designs (e.g., UML, architecture docs), contributing in a rotating design and coding workflow.
- Use AI tools (e.g., GitHub Copilot, LLMs) to streamline coding, debugging, and design innovation.
- Adapt to new tools, APIs, or proprietary systems to tackle evolving challenges.
- Contribute to a trading platform that handles real-time market data, order execution, and financial algorithms.
Who You Are:
- A problem-solving C# .NET Framework expert with 3–7 years of experience, including deep WinForms expertise.
- A multi-threading expert with proven experience handling deadlocks, race conditions, and thread-safe collections (e.g., ConcurrentDictionary).
- Skilled in SQL Server Compact CE or similar embedded databases (SQL Server experience is a plus).
- A master of OOP (SOLID principles, design patterns) who writes clean, scalable code.
- Experienced with existing systems, quickly learning their structure and maintaining consistency with design patterns.
- Comfortable with creating and critiquing technical designs, with a design-before-coding mindset.
- Proficient in using AI tools (e.g., Copilot, ChatGPT) to boost productivity and innovate workflows.
- A quick learner who thrives in complex problem-solving and adapts to new technologies effortlessly.
- Ideally, you have experience in trading platforms or fintech, dealing with low-latency systems and order matching.
- Young (25–35), energetic, and driven to outsmart and outshine your peers.
- Based in Asia, with reliable internet for remote work.
- A strong communicator who excels in collaborative, idea-driven teams.
Standout Qualities:
- You've mastered complex legacy systems, improving speed, intelligence, or efficiency.
- You’ve used AI to solve tricky coding, design, or system integration problems in a way that wowed your team.
- You’ve led a project or design that reshaped 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 contributes to design, code, and challenges each other to innovate.
- The opportunity to contribute to a high-impact trading platform that traders rely on daily.
