Role Overview

Senior Software Developer to build and optimize modular, cloud-native applications using .NET and C#. Developer will work on scalable systems that demand performance, maintainability, and production-grade resilience. This role requires strong coding fundamentals, architectural thinking, and hands-on experience applying GenAI to real-world use cases like document data extraction and intelligent automation.

Key Responsibilities

• Design and develop enterprise-grade modules using .NET Core, C#, and ASP.NET Web API
• Build secure, scalable services for data processing, system integration, and workflow orchestration
• Integrate with cloud platforms (Azure, AWS, or GCP) using services like Functions/Lambda, Blob/S3/Object Storage, Message Queues, Secrets Management, and Monitoring Tools
• Apply GenAI capabilities (e.g., OpenAI, Azure OpenAI) to extract structured data from unstructured documents such as invoices, forms, and contracts
• Optimize SQL queries and schema design for high-volume transactional systems
• Implement robust error handling, logging, and retry logic for production reliability
• Collaborate with architects and stakeholders to translate business requirements into technical deliverables
• Participate in code reviews, performance tuning, and debugging sessions
• Contribute to technical assessments
• Mentor junior developers and promote best practices in modular design and cloud development

Required Skills & Experience

• 7–10 years of professional experience in software development, with a strong focus on .NET Core, C#, and RESTful APIs
• Hands-on experience with cloud platforms such as Azure, AWS, or GCP
• Practical experience using GenAI models (e.g., OpenAI, Azure OpenAI) for tasks such as document data extraction, summarization, or classification — sandbox experimentation or basic API integration is expected
• Familiarity with serverless computing, event-driven architectures, and cloud storage patterns
• Deep understanding of SQL Server or equivalent RDBMS: indexing, joins, transactions, query optimization
• Experience building modular, testable codebases using SOLID principles
• Exposure to CI/CD pipelines (Azure DevOps, GitHub Actions, or equivalent)
• Strong debugging instincts and experience supporting production systems
• Ability to work independently and make sound architectural decisions

Preferred Qualifications

• Experience with low-code platforms (Power Automate, Power Apps, AppSheet)
• Knowledge of multi-tenant SaaS design and secure API development
• Hands-on with Polly, Serilog, or custom middleware
• Familiarity with performance profiling, memory diagnostics, and observability tools
