Key Responsibilities

  • Design and develop high-performance, scalable backend services using C# and .NET Core.
  • Build and maintain RESTful APIs and microservices for a multitenant SaaS platform.
  • Drive engineering best practices including code quality, design patterns, and SOLID principles.

  • Implement and maintain containerized applications using Docker, Kubernetes, and Helm.
  • Ensure robust handling of non-functional requirements including:
    • Tenant isolation
    • Secure multi-tenancy
    • Performance optimization
    • Scalability across tenants
    • Observability and tenant-specific monitoring
  • Develop and maintain automated testing frameworks (unit, integration, E2E).
  • Use CI/CD and GitOps workflows, leveraging tools like Terraform, Helm, and similar for Infrastructure as Code.
  • Collaborate in Agile environments using Scrum or Kanban methodologies.
  • Identify and proactively mitigate risks, dependencies, and bottlenecks.

Must-Have Skills

  • 610 years of backend development experience with strong hands-on skills in:
    • C#, .NET Core
    • RESTful API development
  • Experience in asynchronous programming, event-driven architecture, and Pub/Sub systems.
  • Strong foundation in OOP, data structures, and algorithms.
  • Proficient with Docker, Kubernetes, and Helm.
  • Experience with CI/CD, GitOps, and Infrastructure as Code (Terraform, Helm).
  • Strong understanding of multi-tenant architecture and NFRs:
    • Tenant isolation
    • Shared vs. isolated models
    • Security and resource partitioning
    • Performance tuning per tenant
  • Proficient with relational databases (PostgreSQL preferred), with exposure to NoSQL.
  • Experience working in Agile/DevOps environments.

Nice-to-Have Skills

  • Experience with frontend technologies (React.js) for occasional full-stack collaboration.
  • Knowledge of modern API frameworks: gRPC, GraphQL, etc.
  • Familiarity with feature flagging, blue-green deployments, canary releases.
  • Exposure to monitoring, logging, and alerting systems for multitenant environments.

Preferred Qualifications

  • Bachelors or Masters degree in Computer Science, Engineering, or related field.
