.NET / React Full Stack Developer (Mid–Senior)

About the Role

We are an enterprise organisation seeking an experienced .NET / React Full Stack Developer to join our technology team on an exciting greenfields build. Working from well-defined requirements provided by a dedicated architect and business analyst, you will focus purely on what you do best — writing high-quality code and ensuring the integrity of our AI-assisted development workflow.

This is a modern development environment where AI tooling is used extensively to accelerate delivery. Your role will be central to maintaining code quality, reviewing AI-generated output for correctness, security, and compliance, and ensuring the codebase remains clean, consistent, and production-grade.

You will work closely with a collaborative development team across a full .NET and React stack, building enterprise-grade applications backed by a robust PostgreSQL and Azure-hosted infrastructure.

Key Responsibilities

• Develop high-quality .NET / C# applications following clean architecture principles (DAL, business logic, services)

• Build responsive, component-based front-end applications using React

• Implement data access layers using Entity Framework Core against PostgreSQL

• Build and integrate RESTful APIs as part of the broader enterprise system

• Review AI-generated code critically — assessing correctness, security, performance, and adherence to architectural standards

• Write and maintain automated tests across the full stack, upholding a strong test culture throughout the codebase

• Work within GitHub Enterprise Cloud CI/CD pipelines, ensuring code quality gates and deployment standards are met

• Collaborate closely with fellow developers, the project architect, and business analyst to deliver against requirements

• Maintain clear, consistent coding standards across a greenfields codebase

Required Skills & Experience

Must Have

• 5–15 years of professional .NET / C# development experience delivering production-grade systems

• Strong experience with full-stack development — React front-ends, APIs, business logic, and data access layers

• Solid hands-on experience with React, including hooks, component design, and state management

• Proficiency with Entity Framework Core and relational database development (PostgreSQL preferred)

• Solid RESTful API design and integration experience

• Demonstrated experience with automated testing and a genuine commitment to test-driven culture

• Experience with CI/CD pipelines, preferably GitHub Enterprise Cloud

• Comfortable working in an AI-assisted development environment — reviewing, validating, and refining AI-generated code

Highly Regarded

• Prior experience on greenfields enterprise builds

• TypeScript experience alongside React

What We Offer

• Permanent, full-time on-site role with long-term stability

• Modern, AI-assisted development environment with cutting-edge tooling

• Greenfields project — build something from the ground up, the right way

• Collaborative team with a dedicated architect and BA — you focus on code, not meetings

• Supportive workplace with opportunities for professional development
