The Role:
We are looking for a Senior Fullstack .NET Developer to join our fast-growing Network. In this role, you’ll own the design and implementation of backend services and APIs using .NET (C# / ASP.NET Core), while delivering polished, performant user interfaces using modern frontend technologies and .NET-driven UI frameworks. You will collaborate with product managers, designers, and other engineers to deliver end-to-end features, make architectural decisions, and mentor more junior engineers.
This is a long-term, full-time remote engagement. You’ll have the opportunity to work with modern cloud platforms, CI/CD pipelines, and deliver impactful features in real products used by customers around the world.
What we are looking for:
• 5+ years of professional software development experience, with strong fullstack exposure.
• Relational databases - MSSQL experience.
• 3+ years of production experience with .NET (C#, .NET Core / .NET 6+) and ASP.NET Core.
• Solid knowledge of JavaScript/TypeScript, HTML5 and CSS3, or experience with .NET UI frameworks such as Blazor and Razor Pages.
• Experience with relational databases (e.g., SQL Server, PostgreSQL) and ORM tooling such as Entity Framework Core.
• Strong understanding of RESTful API design and integration patterns.
• Experience with automated testing (unit, integration) and test frameworks for both backend and frontend.
• Practical experience with containerization (Docker) and familiarity with CI/CD pipelines (e.g., GitHub Actions, Azure DevOps, GitLab CI).
• Experience deploying and operating services in the cloud (Azure preferred, AWS/GCP acceptable).
• Ability to work independently and deliver high-quality results in a remote setup.
• Intermediate-advanced English
Nice-to-have:
• Deep experience with TypeScript and modern frontend tooling (Vite, Webpack).
• Proven experience with Blazor, ASP.NET MVC or other .NET-centric UI frameworks.
• Familiarity with microservices patterns, DDD, CQRS or event-driven architectures.
• Experience with container orchestration (Kubernetes).
• Knowledge of message brokers (e.g., RabbitMQ, Kafka, Azure Service Bus).
• Experience with GraphQL and schema design.
• Exposure to performance tuning, caching strategies and observability (logs, tracing, metrics).
Responsibilities:
• Design, implement, and operate scalable backend services using .NET (C#, ASP.NET Core).
• Build and maintain responsive, accessible user interfaces using modern frontend technologies and/or .NET UI frameworks (e.g., Blazor, Razor Pages).
• Design and consume robust RESTful APIs (and optionally GraphQL) and integrate with databases and external systems.
• Ensure code quality through testing (unit/integration), code reviews, and automated pipelines.
• Drive architectural decisions for backend, frontend, and their integration (microservices, monoliths, or hybrid).
• Collaborate with designers and product teams to translate requirements into technical solutions and great user experiences.
• Troubleshoot production issues, optimize performance, and ensure application reliability and security.
• Mentor and coach other engineers, contribute to best practices and team processes.
• Participate in an agile development process and help continuously improve delivery and observability.
• Document design choices, API contracts, and deployment procedures.
