Full Stack Developer - .Net / Azure / React

OtterSoft is seeking a Senior Full Stack Developer with deep expertise in .NET, Azure, React, and AI-powered application development. This role is ideal for a developer who combines strong backend engineering and Azure cloud expertise with deep, hands-on frontend development experience, particularly with React and modern frontend technologies.

We are looking for someone who can work across the entire application stack while bringing a strong frontend perspective to the development of modern, scalable enterprise applications. The ideal candidate should be equally comfortable building sophisticated React user experiences and designing scalable .NET/Azure backend services.

This is an AI-first engineering role. We use AI as a core part of the software development lifecycle—not simply as an occasional productivity tool. We build, ship, test, and iterate quickly, measuring progress through working software and business value.

What You’ll Do

Full-Stack Development

• Design and develop enterprise-grade full-stack applications using React and .NET.
• Own features from technical design through development, testing, deployment, and production support.
• Troubleshoot and resolve issues across the entire application stack.
• Collaborate with architects, product owners, UI/UX designers, QA, and DevOps teams.
• Participate in code reviews, sprint planning, architecture discussions, and technical design sessions.

Frontend Development – Strong Emphasis

• Design, develop, and maintain modern, scalable React applications.
• Build sophisticated, reusable React components and frontend architectures.
• Develop applications using React, TypeScript/JavaScript, HTML5, and CSS.
• Apply modern frontend development practices to create maintainable, scalable applications.
• Implement effective state management, component architecture, form handling, validation, and API integration.
• Optimize frontend performance, responsiveness, usability, and reliability.
• Build responsive applications that work effectively across modern browsers and devices.
• Establish and maintain reusable frontend patterns, components, and development standards.
• Work closely with UI/UX designers and product stakeholders to translate designs and requirements into production-ready experiences.
• Help identify opportunities to improve frontend architecture, performance, maintainability, and overall user experience.

The ideal candidate should have significant hands-on React development experience and should view frontend engineering as a core area of expertise—not simply an extension of their backend responsibilities.

Backend & .NET Development

• Develop highly scalable backend services using C#, .NET 8+, and ASP.NET Core.
• Design, build, and maintain high-performance RESTful APIs.
• Develop secure, scalable backend architectures.
• Implement asynchronous and event-driven processing.
• Optimize application performance across APIs, databases, and cloud infrastructure.

Azure Cloud Development

• Architect scalable backend solutions using Azure services.
• Develop Azure Functions for event-driven and serverless workloads.
• Design and manage Azure API Management (APIM) implementations.
• Build high-performance data solutions using SQL Server and Azure Cosmos DB.
• Implement Azure Service Bus and asynchronous messaging.
• Apply Azure cloud architecture best practices.
• Ensure application security, scalability, monitoring, reliability, and performance.

AI-Powered Development

• Implement Azure AI Search to power intelligent application search and retrieval experiences.
• Develop AI-powered application capabilities using Azure OpenAI and Azure AI Foundry.
• Work with AI-powered search, retrieval, and RAG-based solutions.
• Use AI tools as a primary development accelerator.
• Incorporate AI into architecture, development, testing, refactoring, documentation, and troubleshooting.

What “AI-First” Means Here

AI is embedded into your daily engineering workflow.

You will:

• Use AI for architecture brainstorming and technical problem solving.
• Generate boilerplate and scaffolding rapidly.
• Use AI to refactor and optimize code.
• Build automated tests with AI assistance.
• Automate documentation and API specifications.
• Use AI to troubleshoot and debug applications.
• Continuously improve development velocity through AI.
• Use tools such as **GitHub Copilot, Cursor AI, Claude Code, or similar technologies…
