Job description

Tech Stack: .NET 8, AWS, SQL Server, DynamoDB, Anthropic Claude AI

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.

Requirements

  • 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).
