Build and maintain secure, well-documented RESTful APIs for internal and external enterprise applications.
Develop backend components that integrate with SQL databases, enterprise systems, third-party services, and cloud-native platforms.
Design and optimize database schemas, stored procedures, queries, and data access layers to ensure performance, reliability, and data integrity.
Implement microservices-based architecture patterns, including service-to-service communication, API gateways, resiliency, logging, and monitoring.
Deploy and support backend applications on AWS using cloud-native services, containerized workloads, serverless components, or managed infrastructure.
Collaborate with architects, product owners, data engineers, and application teams to understand requirements and deliver reliable backend solutions.
Implement secure coding practices, authentication, authorization, secrets management, audit logging, and role-based access controls.
Participate in code reviews, technical design discussions, troubleshooting, production support, and performance tuning activities.
Build reusable backend components, API libraries, integration services, and common utilities to improve development efficiency.
Support CI/CD pipelines, automated testing, deployment automation, and environment configuration.
Integrate backend services with LLM-enabled capabilities where required, such as connecting APIs to AI services, RAG pipelines, vector databases, or LLM endpoints.
Create and maintain technical documentation covering architecture, APIs, data flows, deployment steps, dependencies, and operational procedures.

Required Qualifications

Bachelor's or master's degree in computer science, Software Engineering, Information Technology, or a related technical field.
Strong hands-on experience developing production-grade backend applications using C# and .NET Core / .NET.
Proven experience designing, developing, and maintaining RESTful APIs and enterprise backend services.
