Principal Software Engineer, Cloud

Senior Full-Stack .NET Developer – AI-Forward Engineering

Type: Full-time

Level: Senior

About the Role

We’re looking for a senior full-stack .NET developer who treats AI tooling as a core part of their engineering practice. You’ll build and maintain a multi-service technology expense management platform built on .NET 8, working across both backend microservices and modern frontend applications. You should use AI coding assistants (Cursor, GitHub Copilot, Claude, ChatGPT, or similar) fluently, critically, and responsibly, reviewing generated code with the same rigor you’d apply to a junior developer’s PR.

What You’ll Do

Design and implement features across a distributed .NET 8 microservice platform (REST APIs, background workers, message bus handlers)
Build and maintain modern front-end applications using React and TypeScript
Apply Clean Architecture and CQRS patterns to backend services
Author and evolve EF Core database migrations in a shared schema model
Write unit, integration, and end-to-end tests
Use AI coding tools actively for scaffolding, refactoring, code review, and exploration while maintaining quality ownership
Participate in code review with a focus on patterns, correctness, and maintainability
Contribute to and uphold architectural standards and shared patterns across teams

What We’re Looking For

Must-Haves

5+ years of professional C# / .NET development (.NET 6+ preferred)
Strong understanding of dependency injection, async/await patterns, and service lifetime management
Experience with front-end frameworks (React)
Experience with message-driven architecture (Rebus, MassTransit, NServiceBus, or similar)
Comfort working in multi-tenant SaaS environments
Solid SQL / EF Core skills and experience with schema migrations in production systems
Demonstrable experience using AI coding tools as a genuine productivity multiplier, with judgment to catch what they get wrong

Strong Differentiators

Experience with technology expense management, FinOps tooling, or cloud billing APIs (Azure/AWS/GCP)
Background in Clean Architecture / Domain-Driven Design
Experience with spec-driven development and code generation
Experience writing AI-assisted code at scale and helping establish team norms around it

AI Fluency – What We Actually Mean

Use AI tools to accelerate first drafts of handlers, tests, UI components, and migrations
Critically review AI-generated code against architectural patterns and push back when it deviates
Leverage AI for codebase exploration, refactoring proposals, frontend+backend scaffolding, and documentation
Stay current with evolving AI tooling and bring useful techniques back to the team

Tech Stack

.NET 8, C#, ASP.NET Core
React / TypeScript / Blazor (front-end)
Message bus (Rebus, MassTransit, or similar), EF Core (SQL Server)
Azure (App Services, Service Bus, Application Insights)
xUnit, FluentAssertions, FakeItEasy
Cursor / GitHub Copilot (AI-assisted development)
Git, Azure DevOps, PowerShell

What Good Looks Like in This Role

You reach for AI to eliminate boilerplate and then own what it produces
You contribute well-structured backend handlers and clean, testable frontend components
You notice when a handler or UI module is growing unwieldy and extract without being asked
You read the patterns guide before introducing something new
You write backend and frontend tests that describe intent, not just coverage
You treat shared database migrations as carefully as production deployments
