C# Backend AI powered Engineer (Mid level)

About Stackbuld

Stackbuld is a high-end software development company helping global businesses build world-class digital products — from custom apps and agentic AI systems to blockchain platforms and fintech tools.

We combine technical excellence with futuristic thinking to deliver fast, scalable, and secure solutions.

As we grow, we're expanding our engineering team and looking for a solid C# Backend Developer to help us build and scale powerful backend systems.

What You’ll Work On

You’ll collaborate with our core engineering team to:

• Design and develop robust APIs using ASP.NET Core
• Build and maintain scalable backend systems for real-time applications
• Work on real-world fintech, e-commerce, and AI/ML integrations
• Write clean, testable, and maintainable code
• Integrate third-party APIs (payments, CRMs, etc.)
• Optimize performance and implement security best practices

What We’re Looking For

• 2–4 years experience with C# and .NET Core
• Solid understanding of RESTful API design
• Experience with Entity Framework Core and relational databases
• Familiarity with dependency injection, unit testing, and async programming
• Knowledge of Git, CI/CD, and cloud platforms (Azure or others)
• Strong communication skills and ability to work independently

Bonus:

• Experience with background services, messaging queues, or DDD
• Exposure to fintech or high-scale systems

Extra Edge (Highly Valued)

• Ability to “vibe code” with AI tools — effectively using tools like ChatGPT, GitHub Copilot, Cursor, or Claude Code
• Strong understanding of how to combine AI-assisted development with solid engineering principles (not just generating code, but validating, structuring, and scaling it properly)

Recruitment Process

Our hiring process is straightforward and designed to assess both technical strength and real-world problem-solving:

• Application Submission
• Take-Home Assessment
• Technical Interview + Live Coding
