We are seeking an experienced Tech Lead to spearhead the modernisation of a large-scale enterprise application from legacy ASP.NET to a modern .NET 10 Web API and React stack. You will own the technical direction of a cross-functional delivery pod, mentor a team of developers, and drive hands-on engineering across both frontend and backend.
This is a hands-on leadership role — you will write production code, lead architecture decisions, and be accountable for the technical quality of everything your pod delivers. You will work in a structured Agile workplace, collaborating closely with the Solution Architect, QA leads, and client stakeholders across a multi-year, multi-phase modernisation programme.
What You Will Do
Technical Leadership
• Own end-to-end technical delivery of your pod — architecture, design, coding, code review, and quality gates
• Lead the migration from legacy ASP.NET (MVC / Web API / Web Forms) to .NET 10 REST APIs and React 18 frontend
• Define and enforce coding standards, branching strategy, and PR review process across the pod
• Produce Architecture Decision Records (ADRs) for all significant technical choices
• Conduct structured code reviews covering architecture, security, performance, and maintainability — not just syntax
• Identify and resolve technical debt proactively; maintain a tech debt register visible to stakeholders
• Set up and maintain CI/CD pipelines (GitHub Actions / Azure DevOps) with quality gates: SonarQube, unit coverage, OWASP dependency scan
• Collaborate with Solution Architect on cross-pod API contracts, shared services, and infrastructure decisions
Hands-On Engineering
• Design and build .NET 10 Web API microservices using Clean Architecture and Domain-Driven Design patterns
• Build React 18 SPAs: component architecture, Redux Toolkit / Zustand state management, routing, and performance optimisation
• Implement OAuth2 / OIDC / JWT authentication and role-based access control
• Design and optimise relational da
