Position Overview

We are seeking a mid-to-senior level .NET Developer to help build new, modern backend services from the ground up. This role is ideal for someone with strong experience designing scalable APIs, microservices, and event-driven systems using modern .NET.

Our team is building new .NET services that will replace existing Java services, so experience understanding Java-based systems is a plus. The ideal candidate can work independently, collaborate well with cross-functional teams, mentor junior developers, and contribute to strong architecture and engineering practices.

Responsibilities

• Design, develop, and maintain new backend services, RESTful APIs, minimal APIs, and microservices using modern .NET and C#.
• Build scalable systems using Domain-Driven Design, event-driven architecture, and modern architecture patterns.
• Design services with clear domain boundaries, well-defined responsibilities, and maintainable business logic.
• Develop data access layers using Entity Framework, code-first development, migrations, and modern ORM practices.
• Work with relational and No
  
  SQL databases, including schema design, indexing, relationships, data modeling, and query performance.
• Implement dependency injection, middleware, configuration, logging, validation, authentication, and error handling using modern .NET practices.
• Integrate services with messaging and event platforms such as RabbitMQ, Kafka, Azure Service Bus, or similar technologies.
• Use Redis or other caching technologies to improve system performance and reliability.
• Containerize applications using Docker and support deployment into container-based environments.
• Create, publish, and consume NuGet packages, including packages hosted in private repositories.
• Apply object-oriented design, design patterns, SOLID principles, clean architecture, and clean code practices.
• Write and maintain unit tests and integration tests to ensure code quality and system stability.
• Participate in peer code reviews, technical design discussions, and architecture planning.
• Collaborate with product owners, QA, Dev Ops, architects, and other developers in an Agile/Scrum environment.
• Review or understand existing Java services to help design replacement .NET services with improved architecture, scalability, and maintainability.
• Create and maintain technical documentation for APIs, services, architecture decisions, and deployment processes.
• Mentor junior developers and contribute to team learning, engineering standards, and continuous improvement.

Required Skills and Experience

• 5+ years of professional software development experience with C# and .NET.
• Strong experience with .NET Core / modern .NET.
• Experience designing and developing RESTful APIs and minimal APIs.
• Strong understanding of dependency injection, middleware, configuration, logging, validation, and modern .NET application structure.
• Experience designing microservices, service boundaries, and distributed systems.
• Strong understanding of Domain-Driven Design concepts and how to apply them to new application development.
• Experience with event-driven architecture, messaging patterns, asynchronous processing, and distributed communication.
• Hands‑on experience with Entity Framework, code‑first development, migrations, and ORM best practices.
• Strong relational database knowledge, including indexes, foreign keys, constraints, normalization, and query optimization.
• Experience with No
  
  SQL databases and data modeling concepts.
• Experience with architecture and design patterns such as Repository, Unit of Work, CQRS, Mediator, Factory, Strategy, and Clean Architecture.
• Experience with RabbitMQ, Kafka, Azure Service Bus, Redis, or similar technologies.
• Experience with Docker and containerized application development.
• Experience with Azure services and cloud‑based application development.
• Experience creating, publishing, and consuming NuGet packages, including private package repositories.
• Strong understanding of SOLID principles, refactoring, testable code, and maintainable software design.
