  Role Overview
  We are looking for a strong Backend Engineer with proven experience building and maintaining production backend systems using ASP.NET Core within the .NET ecosystem.
  
  This role involves taking ownership of an existing API platform, improving its structure, performance, and reliability. The current system was developed rapidly and requires refactoring, architectural improvements, and stricter engineering practices.
  We expect candidates who can:
  • Understand and refactor complex backend code
  • Design scalable APIs
  • Identify architectural problems and propose solutions
  • Deliver production-grade backend services with minimal supervision
  You will work closely with frontend engineers and product stakeholders to build stable, secure, and maintainable backend systems.
  
  Key Responsibilities
  1. Backend System Development & Code Quality
  Design, develop, and maintain backend APIs using:
  • C#
  • ASP.NET Core
  • Modern .NET runtime
  Responsibilities include:
  • Writing clean, maintainable, and testable backend code
  • Refactoring poorly structured or legacy code
  • Enforcing consistent project structure and coding standards
  • Implementing proper layered architecture (Controllers, Services, Data Access)
  Candidates must be comfortable working with existing systems and improving them, not just building greenfield projects.
  
  2. API Architecture & System Design
  Design and implement robust RESTful APIs to support web applications and external integrations.
  Responsibilities include:
  • Designing clear API contracts and data models
  • Implementing proper validation and error handling
  • Designing maintainable service layers
  • Supporting future scalability and feature growth
  Candidates should demonstrate solid backend architecture thinking, not just endpoint implementation.
  
  3. Data Access & Database Performance
  Design and maintain efficient database interactions using:
  • Entity Framework Core
  • Microsoft SQL Server or other relational databases
  Responsibilities include:
  • Writing efficient queries and understanding query performance
  • Managing schema migrations and database structure
  • Preventing performance issues such as N+1 queries
  • Ensuring data consistency and integrity
  Strong candidates should understand how backend code impacts database performance.
  
  4. Performance & Reliability
  Improve backend performance and reliability across services.
  Responsibilities include:
  • Implementing asynchronous processing
  • Reducing unnecessary database calls
  • Identifying performance bottlenecks
  • Ensuring APIs remain stable under real-world load
  Candidates should demonstrate the ability to diagnose and fix backend performance issues.
  
  5. Security & Backend Best Practices
  Follow secure backend development practices.
  Responsibilities include:
  • Implementing authentication and authorization mechanisms
  • Protecting APIs from common vulnerabilities
  • Implementing proper input validation and error handling
  • Ensuring sensitive data is handled securely
  Backend developers must understand that security is enforced on the server side, not the client.
  
  6. Engineering Ownership & Collaboration
  Work closely with engineers and stakeholders to improve the overall system.
  Responsibilities include:
  • Participating in code reviews
  • Contributing to technical decisions
  • Improving development practices and architecture
  • Taking ownership of backend quality and maintainability
  We expect engineers who actively improve systems, not just complete assigned tasks.
