About the role

Fullstack Software Engineer, .NET / React

Position Overview:

We are hiring a Fullstack Software Engineer with strong experience building production applications using .NET/C# on the backend and React on the frontend. This is a high-ownership, client-facing role where you will work across multiple projects, delivering end-to-end solutions for diverse business domains. You will own features from database design through API development to frontend implementation, working directly with clients, Product Owners, and cross-functional teams to translate business requirements into robust, scalable applications. The work spans greenfield product development, enterprise SaaS platforms, internal tools, and modernization of legacy .NET systems to modern architectures. This is not a ticket-taker role — you are expected to make architectural decisions, lead technical conversations with stakeholders, and deliver production-quality software with accountability for reliability, performance, and maintainability. The role requires 3-5+ years of professional experience and is ideal for a product-minded engineer who thrives in a consultancy environment with varied and challenging projects.

Key Responsibilities:

Own features end-to-end: from React UI through ASP.NET Core API design to SQL Server database implementation
Work across multiple client projects, adapting to different domains, codebases, and team structures
Partner with Product Owners, clients, and Subject Matter Experts to translate business requirements into shipped solutions
Write clean, maintainable, well-tested code with a focus on long-term quality and team velocity
Design and build scalable APIs and microservices using ASP.NET Core and .NET 6/7/8
Implement data access layers using Entity Framework Core with proper repository and unit-of-work patterns
Design and optimize SQL Server databases: schema design, indexing strategies, query performance tuning, and migrations
Apply architectural patterns (CQRS, MediatR, DDD) where appropriate to manage complexity in enterprise systems
Build responsive, accessible, and performant user interfaces using React and TypeScript
Implement modern state management, component composition, and data fetching patterns
Integrate frontend applications with backend APIs and handle authentication, authorization, and error states gracefully
Design, deploy, and manage applications on Microsoft Azure (App Service, Azure Functions, Azure SQL, Blob Storage)
Build and maintain CI/CD pipelines using Azure DevOps or GitHub Actions
Implement containerized deployments using Docker and manage application configuration across environments
Participate in client-facing technical discussions, requirement gathering, and solution design sessions
Communicate technical trade-offs clearly to non-technical stakeholders
Deliver work within agreed timelines while maintaining quality standards
Make architectural decisions and lead technical conversations with stakeholders
Proactively identify improvements and ramp up on new project contexts quickly

Required Skills:

3-5+ years of professional experience building production applications with C# / .NET and React
Strong proficiency in ASP.NET Core (Web API, MVC) and .NET 6 or later
Hands-on experience with Entity Framework Core for data access and database migrations
Solid SQL Server skills: schema design, writing complex queries, indexing, and performance optimization
Production experience building React applications with TypeScript, including state management and API integration
Understanding of RESTful API design principles, authentication (JWT, OAuth 2.0), and authorization patterns
Experience with at least one cloud platform (Azure preferred) for deploying and managing production workloads
Familiarity with CI/CD pipelines and containerization (Docker)
Experience working on client-facing or consultancy projects with direct stakeholder interaction
Ability to work independently, manage priorities across projects, and communicate clearly in a remote team
Languages: C#, TypeScript / JavaScript, React, HTML5, CSS3, T-SQL, Git

Preferred (Bonus) Skills:

Experience with microservices architecture, CQRS, MediatR, or Domain-Driven Design in .NET
Familiarity with message brokers (RabbitMQ, Azure Service Bus) for event-driven architectures
Experience with Azure-specific services: Azure Functions (serverless), Azure AD (identity), Application Insights (monitoring)
Working knowledge of Redis for caching, SignalR for real-time features, or gRPC for service communication
Exposure to AI/ML integration: connecting .NET applications with LLM APIs, building AI-assisted features, or working with Azure Cognitive Services
Experience with legacy .NET Framework modernization to .NET 6/7/8 and modern architectures
Background in automated testing strategies: unit testing (xUnit/NUnit), integration testing, and end-to-end testing
Familiarity with Terraform or Bicep for Infrastructure as Code
Experience with Agile delivery in a consultancy or multi-project environment
Prior experience mentoring junior developers or leading small technical teams
