Agile coach

Test-Driven Development (TDD) Coach –. NET & React ApplicationsAbout the RoleThe 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, Wire Mock) to ensure reliable integration between microservices and APIs.- Collaborate with Solution Architects and Dev Ops 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.Qualifications- 10+ years of experience in software engineering or test automation with deep understanding of TDD and unit testing practices.- Strong command of C#,. NET Core, and React frameworks, including modern application architectures (microservices, RESTful APIs).- Proven experience in establishing TDD adoption frameworks, conducting workshops, and mentoring developers on test-first design.- Hands-on experience in contract testing and API mocking for service-level validation.- Ability to analyze and refactor legacy applications to become testable and maintainable under modern design principles.- Excellent communication, facilitation, and leadership skills to drive cultural and technical transformation.- Familiarity with Dev Sec Ops and CI/CD practices, ensuring early and automated validation of code quality.Required Skills- Backend (. NET)-. NET Framework (for legacy apps) and. NET 8 (LTS)- Language: C#- API Development: ASP. NET Core Web API- ORM: Entity Framework Core 8- No SQL Databases: Mongo DB, Redis (for caching)- Architecture: Clean Architecture and Microservices- Dependency Injection: Built-in with. NET Core- Frontend (UI)- Frameworks: React (preferred) / Angular / Blazor- UI Libraries: Material UI- Testing Frameworks: Jest, React Testing Library- Testing & Quality Engineering- Unit Testing: NUnit (for. NET), Jest (for React)- Contract Testing: Pact, Wire Mock (preferred)- Test Management: Azure Dev Ops Test Plans / Zephyr for Jira- CI/CD Integration: Git Hub Actions, Azure Pipelines, or JenkinsPreferred Skills- Experience in agile development environments with in-sprint testing and continuous integration practices.- Prior exposure to Clean Code, SOLID principles, and refactoring techniques.- Knowledge of cloud-native architectures (Azure / OCI) and containerization (Docker, Kubernetes).
