Backend Engineer (.NET Core)

About the Role

We are looking for an experienced mid-Senior Backend Developer responsible for building and scaling cloud-native backend services that power mission-critical AI products. This role is ideal for engineers who are comfortable designing cloud-oriented systems using modern engineering practices, and who have strong foundations in distributed systems and multi-threaded programming. You will work closely with product, frontend, and platform teams to deliver highly reliable, scalable, and secure backend systems in a fast-paced, agile environment.

Responsibilities

• Design and build cloud-native backend services and APIs that are scalable, secure, and production-ready.
• Develop and maintain backend components using C# / .NET (preferably .NET 8) following modern engineering standards.
• Contribute to system architecture for distributed systems, including service-to-service communication, resilience, and scalability patterns.
• Build systems that handle concurrency and multi-threading safely and efficiently (e.g., async patterns, thread safety, race conditions, performance tuning).

Requirements

• Min 3+ years of backend engineering experience with strong hands-on expertise in C# and .NET Core (V6 and above).
• Strong experience designing and building RESTful APIs and backend services.
• Proven ability to build cloud-oriented systems (AWS/Azure/GCP) using modern practices such as containerization, infrastructure awareness, and CI/CD.
• Solid understanding of distributed systems fundamentals and multi-threading / concurrency concepts.
• Strong SQL knowledge and experience with relational databases.
