Lead Developer, Cloud Computing

Lead Developer - Remote UK - £70,000-£80,000 DOE

We're working with an organisation that is building a new platform and is looking for a Lead Developer to take technical ownership from day one.

This is an excellent opportunity for a senior full-stack engineer who thrives in a structured, enterprise-grade environment and enjoys staying hands-on while defining architecture, setting engineering standards, and driving secure delivery practices within a "fail fast" product mindset.

You'll lead engineering on the first product within a wider cloud transformation strategy. The platform consists of a .NET MAUI mobile application (iOS & Android), an Angular 21 web application, and Azure-hosted backend services built using modern Microsoft technologies.

Reporting to the Product Owner, you'll play a pivotal role in defining architectural standards, implementing robust Dev Ops practices, and ensuring security, performance, and maintainability are embedded from the outset.

This role blends hands-on development, architectural leadership, and close collaboration with Product, UX (Figma), and QA teams. The expectation is high-quality, production-ready code with strong test coverage and fully automated deployments.

You will be responsible for:

• Writing secure, production-grade, well-tested code across backend, frontend, and mobile
• Taking architectural ownership of APIs, mobile offline patterns, and Azure infrastructure
• Designing and building RESTful services using modern .NET and clean architecture principles
• Leading Infrastructure as Code implementation using Bicep
• Driving CI/CD maturity (Bitbucket preferred) with strict SDK and dependency version control
• Ensuring OWASP-aligned secure coding practices and GDPR compliance
• Collaborating with QA to support automated and manual test strategies
• Documenting architectural decisions (ADRs) and maintaining clear technical communication

Core technologies:

• .NET 10 / ASP.NET Core Web API
• Entity Framework Core with Azure SQL
• .NET MAUI (offline-first mobile design)
• Microsoft Azure (App Services, Azure SQL, Blob Storage, Key Vault, Application Insights)
• Azure Entra  & RBAC
• Angular 21
• Type Script (strict mode)
• Dev Express Dev Extreme (v25)
• NUnit, Vitest, and Playwright

• 7+ years' commercial software development experience
• Minimum 3 years working within fast-paced, "fail-fast" delivery environments
• At least 2 years in a leadership position
• Strong expertise in modern .NET and API design
• Proven Angular experience (v15+)
• Hands-on Azure architecture and deployment experience
• Experience implementing Infrastructure as Code (Bicep preferred)
• Experience integrating Azure Entra
• Strong understanding of CI/CD and enterprise Dev Ops practices
• Security-first mindset with knowledge of OWASP Top 10
• Experience building high-performance, enterprise-grade systems

• £70,000-£80,000 (DOE)
• Remote working
• Opportunity to define technical standards from the ground up
• High-autonomy role within a senior engineering environment
• Long-term opportunity to shape future cloud-based products

This is a standout opportunity for a hands-on technical leader who wants genuine ownership of architecture, tooling, and engineering standards within a secure, Azure-first ecosystem.
