Senior .NET Software Developer

We are seeking a motivated and talented individual to join our team as a Senior .Net Software Developer. In this role, you will design and develop distributed microservices for Quake Global's IoT asset management platform. You will work with event-driven architecture, message-driven systems, and modern .NET technologies to build scalable, cloud-native solutions. You will be a good fit if you have deep expertise in microservices architecture, learn new skills quickly, and work well independently and as a part of a team to build quality solutions.

DUTIES AND RESPONSIBILITIES:

• Design, implement, and test distributed microservices for Quake Global's IoT asset management platform.

• Architect and develop event-driven systems using message-driven architecture patterns.

• Build RESTful APIs and asynchronous message handlers for microservices communication.

• Implement authentication, authorization, and security patterns using enterprise identity providers.

• Design and optimize database schemas, Entity Framework Core models, and data access patterns.

• Work with the team on coding, specification development, integration testing, and code coverage generation.

• Deploy and maintain containerized applications on Kubernetes infrastructure.

• Implement comprehensive health checks, monitoring, and observability solutions.

• Debug distributed systems issues, document solutions, and follow software documentation processes.

• Work closely with systems engineers and other teams in developing the product.

• Perform other related duties as assigned by management.
