We are building a sophisticated CRM and Asset Management platform from the ground up, and we need a Senior .NET Developer to take total ownership of the backend. You’ll be one of two developers in a tight knit team, working alongside a Front-end specialist.

This isn't just about maintaining code; you will be the architect of our cloud infrastructure, the designer of our hybrid database strategy, and the lead on integrating Anthropic Claude AI for intelligent automation.

Technical Requirements:

• Core Backend: C# and .NET 6/7/8 using ASP.NET Core Web API.
• Hybrid Data: You’ll lead a dual-database approach using SQL Server (Entity Framework Core) for relational CRM data and AWS DynamoDB for flexible, user-defined asset records.
• AWS Infrastructure: Hands on management of EC2, ECS, RDS, and S3, including setting up CI/CD pipelines (GitHub Actions or CodePipeline).
• AI Integration: Experience with the Anthropic Claude API (or similar LLMs).
• Security: Implementing robust authentication via JWT, OAuth 2.0, and ASP.NET Core Identity.

Other Requirements:

• Autonomy: You are comfortable being the sole backend developer, making architectural decisions.
• Problem Solver: You know when to use a relational schema and when to lean on NoSQL for speed and flexibility.
• Collaborator: You can design clean, documented APIs (OpenAPI/Swagger) that make life easy for your front-end partner.
• Agile Mindset: You enjoy a fast-paced environment where you can influence the product roadmap.

Desirable:

• Building CRMs or complex platforms from scratch.
• Experience with MediatR, CQRS, or event-driven background processing (SQS/Lambda).
• AWS Certifications (Developer or Solutions Architect).
