What You'll Do

• Contribute to a robust C#/ASP.NET Core codebase with architectural insight and hands-on development.

• Design and evolve scalable, performant system architecture.

• Model relational data in SQL Server, optimizing schema and queries for efficiency.

• Build and maintain RESTful APIs that expose well-structured data models.

• Implement asynchronous messaging patterns (e.g., MQTT, pub/sub) for real-time telemetry and control.

• Drive best practices through code reviews, mentorship, and continuous improvement.

• Collaborate with hardware teams to integrate legacy and modern control protocols.

• Contribute to system documentation (UML, C4) and architectural clarity.

• Develop CI/CD pipelines and automated testing systems.

What You Bring

• 5+ years of professional experience building full-stack web applications.

• Strong expertise in C#/ASP.NET Core, SQL Server, and web technologies, e.g., React.

• Solid understanding of software architecture, best practices and design patterns (MVC, repository/unit-of-work, CQRS, Domain-Driven Design).

• Experience with asynchronous/event-driven architectures (e.g., MQTT).

• Familiarity with DevOps best practices, unit testing, and agile development.

• Bachelor's degree in Computer Science, Engineering, or related field.
•  
• This position is not eligible for employer-sponsored work authorization now or in the future. Applicants must be legally authorized to work in the United States without requiring current or future employer sponsorship.

Experience with containerization and orchestration (Docker, Kubernetes).

Familiarity with cloud-native services and serverless patterns (Azure Functions, AWS Lambda).

Experience with front-end testing and C# testing frameworks.
