About Us: We’re a fast-moving fintech team building a high-performance trading platform that empowers traders worldwide. Based across Asia, we’re a small, collaborative group obsessed with bold ideas, clean code, and rigorous design to deliver real-time, low-latency solutions. 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.

How to Apply: Send your resume, GitHub/LinkedIn profile, and a short note describing how you’ve outsmarted a tough technical challenge (e.g., multi-threading, system integration, or AI-driven solution) to hiring@jigsawtrading.com.

Bonus points: Include a sample technical design, a code snippet showcasing multi-threading or system integration, or an example of how you used AI to innovate and reduce coding implementation times.

Application Deadline: April 30th, 2025

Challenge Us: If you can outthink our team, master our systems, and build trading tech that blows us away, we want you. Apply now and show us what you’re capable of!
