Agile Coach

Test-Driven Development (TDD) Coach – .NET & React Applications

About the Role

The TDD Coach will be responsible for coaching and enabling development teams to adopt test-driven development practices across backend (.NET) and frontend (React) applications. The role requires hands-on expertise in designing, implementing, and guiding teams on unit testing, mocking, and contract testing frameworks, ensuring code quality, maintainability, and continuous feedback as part of the shift-left quality transformation.

Responsibilities

• Coach and Mentor Developers on TDD principles, unit test design patterns, and refactoring techniques across both backend (.NET) and frontend (React) codebases.
• Establish and enforce TDD discipline within development sprints to ensure code quality and test coverage goals are met before integration.
• Develop and standardize unit testing frameworks and templates using NUnit (for .NET) and Jest (for React), integrating them into the CI / CD pipelines.
• Guide teams on effective mocking strategies using Moq or NSubstitute (.NET) and Axios mocking (React) to isolate dependencies and validate code behavior.
• Enable Contract Testing adoption using suitable frameworks (e.g., Pact, WireMock) to ensure reliable integration between microservices and APIs.
• Collaborate with Solution Architects and DevOps Engineers to embed quality gates and TDD compliance within automated build and deployment workflows.
• Review existing unit and integration test suites, identify technical debt, and provide actionable refactoring recommendations.
• Provide hands-on support to developers during pairing sessions to implement test-first approaches and build a quality-first engineering culture.
• Track TDD adoption metrics (e.g., test coverage, defect leakage, build quality) and present progress to engineering leadership.
• Continuously research and recommend emerging tools and frameworks in the testing ecosystem to enhance productivity and maintainability.
