This is a unique opportunity to be part of our first on-site office in India, located at the emerging IT hub in Tirupati, Andhra Pradesh (APEITA IT Park). While the initial 3–4 months will be remote, we are excited to build a collaborative hybrid environment in Tirupati.
The Role
We are looking for a skilled Backend Engineer with strong experience in .NET, C#, SQL Server, and API development to build scalable backend systems for our AI-powered healthcare platforms. You will work on complex SQL queries, stored procedures, healthcare/EHR integrations, and modern AI applications. Experience with React.js is expected to enable effective collaboration with frontend engineers and end-to-end troubleshooting.
Key Responsibilities
- Backend Development: Design, develop, and optimize backend applications using C# and .NET / .NET 8. Build scalable REST APIs, implement business logic using clean architecture and design patterns, and develop reusable services, repositories, and middleware. Work with ASP.NET Core Web API, Entity Framework Core, and Dapper. Implement authentication and authorization using JWT, OAuth 2.0, and role-based access control.
- Database Development: Strong hands-on experience with Microsoft SQL Server. Design and optimize database queries, views, functions, and complex Stored Procedures (CTEs, temporary tables, TVPs, transactions, window functions, dynamic SQL, JSON/XML processing). Analyze and resolve SQL performance issues including deadlocks, blocking, and indexing problems. Perform database migrations and schema changes safely across environments.
- API Development & Integration: Develop and integrate REST APIs with internal and external systems. Experience with JSON/XML, OAuth 2.0, JWT, webhooks, third-party APIs, payment APIs, cloud APIs, and healthcare APIs. Capable of understanding third-party API documentation, creating integration services, handling authentication/token management, and troubleshooting integration failures.
- AI Integration: Experience integrating AI capabilities (OpenAI or other LLM APIs) into backend applications. Responsibilities include building AI-powered backend services, implementing prompt-based workflows, working with structured AI/JSON responses, and implementing AI-assisted clinical/document processing, summarization, and classification workflows. Experience with embeddings, vector databases, and RAG (Retrieval-Augmented Generation) is a plus.
