Job Description:

This is a full-time
ON-SITE
role for a talented Senior Backend Software Engineer to join our dynamic team in our Karachi office.

Candidate must have at least 5+ years of hands-on experience in .NET Core backend development, microservices architecture, API development, SQL Server optimization, and strong backend design patterns including MVVM.

You will be responsible for building highly scalable, secure, and performant backend services following modern software engineering practices.

This role requires deep expertise in backend architecture, microservices patterns, database design, security standards, and DevOps tools like GitHub Actions and Azure DevOps.

This Job Is Not for You If:

  • You are considering working Remotely or Hybrid.
  • You rely on ChatGPT for fundamental learning, such as figuring out how to connect APIs to databases, rather than using it as a tool to enhance productivity and professional efficiency.
  • You do not meet performance expectations, as we continuously evaluate work and take necessary actions, including termination, if red flags arise.

Experience: 5+ years

Timings: 10:00 am – 7:30 pm (Pakistan time)

Role and responsibility:

  • Design, develop, and optimize .NET Core microservices and RESTful APIs.
  • Architect and maintain SQL Server databases with efficient schema design, query optimization, stored procedures, and indexing strategies.
  • Implement secure authentication and authorization mechanisms (OAuth 2.0, JWT, IdentityServer).
  • Apply MVVM design patterns and maintain clean separation between domain models, API contracts, and business logic.
  • Build scalable, distributed systems with best practices in microservices architecture (service discovery, circuit breakers, resilience patterns).
  • Develop efficient, maintainable, and unit-tested code across the backend.
  • Collaborate with DevOps teams to deploy and monitor applications using GitHub Actions and Azure DevOps.
  • Participate in code reviews, mentor junior developers, and promote backend best practices.

Key Skills Required:

  • 5+ years of experience as a Backend Developer.
  • Strong command of .NET Core (C#, ASP.NET Core, Web API, Entity Framework Core).
  • Deep understanding of Microservices Architecture and building distributed backend systems.
  • Expertise in SQL Server database design, query tuning, stored procedures, and indexing.
  • Experience applying MVVM (Model-View-ViewModel) pattern in backend API and service layers.
  • Knowledge of secure API development (OAuth 2.0, OpenID Connect, JWT).
  • Familiarity with Azure DevOps, GitHub Actions, and CI/CD pipelines for backend services.
  • Good understanding of clean architecture, domain-driven design (DDD) principles is a plus.
  • Experience with unit testing frameworks like xUnit or NUnit.
  • Strong understanding of security best practices, authentication and authorization.
  • Experience with Agile methodologies, DevOps practices, and cloud deployment strategies.

Nice to have: (Hint: Having bonus skills will move you to the top of list)

  • Bonus 1:
    Experience developing real-time communication applications (audio/video calling features).
  • Bonus 2:
    Hands-on experience integrating Twilio APIs for communication solutions.
  • Bonus 3:
    Experience using SignalR for real-time data streaming and notifications.
  • Experience working in payment gateway integrations.
  • Hands-on experience with Azure cloud services.
  • Familiarity with Docker and Kubernetes for containerized microservices.
  • Knowledge of event-driven architectures (e.g., Azure Service Bus).
