We are seeking an experienced Tech Lead to spearhead the modernisation of a large-scale enterprise application from legacy ASP.NET to a contemporary .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 environment, collaborating closely with the Solution Architect, QA leads, and client stakeholders across a multi-year, multi-phase modernisation programme.
Own end-to-end technical delivery of your pod - architecture, design, coding, code review, and quality gates

- 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
- Set up and maintain CI/CD pipelines (GitHub Actions / Azure DevOps) with quality gates: SonarQube, unit coverage, OWASP dependency scan
- 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




- Design and optimise relational database schemas (SQL Server / PostgreSQL) write complex LINQ and EF Core queries
- Write unit, integration, and contract tests as a core part of the Definition of Done

Lead the technical approach for migrating legacy ASP.NET code to .NET 10 - analysis, characterisation testing, phased migration, parity validation

- Use GitHub Copilot and AI-assisted tooling to accelerate migration while maintaining review discipline
- Ensure all migrated code has adequate unit test coverage before merge - parity tests are non-negotiable

Lead a pod of 4-6 engineers (mix of senior, mid, and junior developers)

- Run daily technical standups, remove technical blockers, and escalate risks to the Architect early
- Mentor mid and junior developers through pair programming, code reviews, and 1:1 technical guidance
- Make resourcing recommendations and flag capacity risks to the Delivery Manager

Agile Delivery (Added Advantage)

- Participate in Scrum ceremonies - Sprint Planning, Daily Standup, Sprint Review, Retrospective, Backlog Grooming
- Collaborate with the Product Owner / BA to refine user stories, provide technical input on acceptance criteria, and raise technical stories
- Provide accurate SP estimates track sprint progress and flag scope risk early
- Support the Scrum Master in removing impediments with a technical root cause
- Champion the Definition of Done - ensure every story that ships meets quality, test, and documentation standards
