📋 Description

• Design and build business logic and domain modules in an ASP.NET Core API following Clean Architecture principles. • Build and maintain asynchronous background processing services using a .NET worker for document-heavy workflows coordinated through message queues. • Develop and maintain multiple Next.js/React applications for internal operations/back-office tooling and external/customer-facing portals. • Share a common package layer across front-end applications. • Design relational data models and write efficient data access code using EF Core/PostgreSQL. • Integrate cloud-native infrastructure including message queues, blob storage, secrets management, and managed identity providers. • Implement authentication and authorization across workforce and external/customer identity boundaries. • Collaborate on API contracts and shared TypeScript types consumed by front-end applications. • Participate in architectural decisions supporting a modular, maintainable, well-tested monolith. • Build human-in-the-loop tooling for operators to review, correct, and approve AI-assisted extraction results with full traceability. • Write and maintain automated tests across the stack and participate in CI/CD pipeline health. • Participate in code reviews and technical design discussions, and mentor less experienced engineers.

🎯 Requirements

• 8+ years of professional software development experience, with deep expertise in C# / .NET (ASP.NET Core). • 4+ years building production front-end applications with React, including Next.js (App Router, server components/actions, route handlers). • Strong understanding of Clean/Layered Architecture, domain modeling, and separation of concerns in non-trivial back-end systems. • Experience with relational databases and ORMs (EF Core or equivalent), including migrations and query performance. • Solid TypeScript skills and comfort working in a monorepo with shared, versioned internal packages. • Experience with cloud infrastructure (Azure preferred; AWS/GCP equivalents considered), including messaging/queues, object storage, and secrets management. • Experience implementing or integrating OAuth2/OIDC-based authentication, ideally with enterprise identity providers such as Microsoft Entra ID or similar. • Strong automated testing discipline: unit, integration, and contract testing on both back end and front end. • Comfortable working across the full stack without hand-offs, from database schema to API to UI. • Excellent communication skills and experience working in a small, senior, high-autonomy engineering team.
