About Us

For 20+ years, we’ve been the market leading in big data analytics for U.S. —empowering brokers, investors, and analysts with real-time market intelligence.

Our engineering team values practical problem solving, clean architecture, ownership, and continuous improvement. We work remotely, move quickly, and embrace modern development practices—including AI-assisted software engineering.

 

About the Role

We're looking for a hands-on Backend C# Developer who enjoys building reliable, scalable backend systems and uses modern AI development tools to improve productivity without compromising code quality.

You'll develop APIs, backend services, and data-processing applications while collaborating closely with experienced engineers in a fast-moving remote environment.

This role is ideal for someone who combines strong backend fundamentals with an AI-first engineering mindset.

This is a hands-on mid-level backend engineering role focused on building production systems rather than leading teams or managing people.

  • Optimize SQL Server databases and application performance
  • Troubleshoot production issues and deliver reliable solutions
  • Use AI development tools (e.g., Cursor, Claude Code, GitHub Copilot, ChatGPT) to accelerate development while maintaining high code quality
  • Collaborate with engineers to deliver clean, scalable, and maintainable software

Sneak peek of projects:

  • Big Data Orchestration
  • Data Warehousing in SQL Server & NoSQL
  • API Design with C# 13 / .NET 9

 

What We're Looking For

  • 2+ years of commercial backend C#/.NET development experience (2–6 years preferred)
  • Good written and spoken English
  • Strong experience building REST APIs
  • Solid SQL Server and relational database skills
  • Experience debugging and maintaining production applications
  • Regularly uses AI-assisted development tools (Cursor, Claude Code, GitHub Copilot, ChatGPT, etc.) as part of their daily workflow.
  • Able to work independently in a remote environment

Nice to Have

  • Experience with Azure
  • Experience with Docker and CI/CD pipelines
  • Entity Framework
  • Experience integrating AI or third-party APIs

We offer:

  • Location Independent / 100% Remote
  • $3000–$3500 USD/month
  • Long-term opportunity with a stable U.S. technology company
  • Exposure to modern backend architecture and AI-assisted software development
