Responsibilities:
- API Development & Data Integration: Design, code, and optimize secure multi-tenant APIs using C# and .NET Core that dynamically query and aggregate data across Amazon DynamoDB, PostgreSQL, and varied external client data sources.
- Technical Guidance: Provide clear architectural requirements to DevOps and Network Engineering teams regarding application infrastructure needs.
- Integration Testing: Collaborate with network and infrastructure peers to validate secure backend connections to external client data centers.
- Cross-Network Troubleshooting: Diagnose, isolate, and debug end-to-end data routing issues between the AWS-hosted API and remote external databases.
Requirements:
- This is a hands-on backend engineering role for a developer who will build and deploy a multi-tenant SaaS application on AWS.
- You will write high-performance APIs using C# and .NET that communicate with DynamoDB, PostgreSQL, and various external client data sources.
- You do not need to perform network-level coding; instead, you will collaborate with DevOps and Network Engineers to guide infrastructure setup, test hybrid connectivity, and troubleshoot cross-network data access issues.
- Languages & Frameworks: Expert-level C#, .NET Core
- Data Stores & Integration: Deep hands-on experience with Amazon DynamoDB, PostgreSQL (Entity Framework Core or Dapper), and writing abstract data access layers to query heterogeneous external data sources.
- SaaS Multi-Tenancy: Real-world experience implementing application-level tenant isolation, data partitioning, and tenant context middleware.
- Hybrid Networking Concepts: Solid conceptual understanding of VPCs, AWS PrivateLink, and firewalls to effectively guide networking peers.
- DevOps Liaison: Basic familiarity with cloud infrastructure deployment (Terraform, AWS CDK) to streamline pipeline integrations.
- Experience: 5+ years of active, hands-on backend development building distributed systems on AWS.
- Communication: Strong collaborative skills to translate complex application data requirements into actionable tasks for infrastructure teams.
- Wanted to clarify that this is an Architect/Senior Developer role that requires strong hands-on coding and troubleshooting experience.
- The position is not focused solely on solution design or high-level architecture; it involves active participation in development, debugging, problem resolution, and technical implementation.
- The ideal candidate should have a proven track record of writing production-quality code, investigating and resolving complex technical issues, and contributing directly to the delivery of software solutions while also providing architectural guidance when needed.
