Role Description We're hiring a C# developer who can architect and ship production-grade backend systems from day one. This starts as a contract engagement with the explicit intent to convert to full-time. You'll design scalable APIs, manage Azure infrastructure, and integrate AI capabilities directly into the product — not as a side feature, as core architecture. If you've built serious .NET systems on Azure and you've worked with LLMs beyond the tutorial level, we want to talk. Responsibilities - Design, build, and maintain high-performance Web APIs using C# and .NET Core — clean architecture, no shortcuts, built to last. - Architect and manage cloud infrastructure on Azure: App Services, Functions, SQL Database, Service Bus, Key Vault, and Entra ID. - Integrate LLMs and AI features directly into the application ecosystem — Azure OpenAI, semantic search, vector databases, embeddings. - Participate in foundational system design decisions with an eye on long-term maintainability, not just the current sprint. - Document codebase logic and API endpoints clearly enough that the next engineer doesn't need to ask you how anything works. - Communicate architectural and AI trade-offs to non-technical stakeholders in plain language, in writing, without being asked twice. Qualifications - C# and .NET mastery. Advanced proficiency in C# on .NET 6/8+. You write async code naturally, use LINQ without abusing it, and your Entity Framework Core usage won't embarrass you in a code review. You understand OOP and SOLID well enough to apply them, not just cite them. - Azure ecosystem. You've deployed and managed real applications on Azure — not just followed a tutorial. App Services, Functions, Key Vault, Azure Active Directory/Entra ID. You know what breaks at scale and how to design around it before it does. - API architecture. Deep understanding of RESTful design, microservices, API gateways, rate limiting, and performance tuning. OAuth2 and JWT aren't concepts you look up — they're things you've implemented, debugged, and secured in production. - AI integration. Practical experience with LLMs in production: OpenAI API, Azure OpenAI, prompt engineering, semantic search, embeddings, or vector databases like Pinecone or Azure AI Search. You've built intelligent features into a real product, not a demo. - Product ownership mindset. You build for the long haul. You think about what happens six months after you ship, not just whether the PR passes CI. This is a contract-to-hire role — we're evaluating fit for a permanent position from day one. - Documentation discipline. You document as you build. API endpoints, architectural decisions, data flows — clear enough that the codebase can be handed off without a knowledge transfer call. - Proactive communicator. You flag blockers early, explain trade-offs clearly, and don't disappear between check-ins. Async, in writing, with enough context that nobody needs to follow up. Requirements - Contract engagement with a defined path to full-time conversion — not "maybe someday," a real track. - Fully remote, US timezone. - Direct access to decision-makers — no PM layers between you and the people who own the product. - Real architectural ownership from day one — you're not implementing tickets, you're making design decisions. - Tooling budget for APIs, infrastructure, and whatever you need to do the job well. - A peer network of senior engineers and agentic builders working on overlapping projects.
