Our client is building a web platform that delivers modern, cloud-based experiences aligned with Sensei Cloud. The application is modular in nature and will grow over time. As a Full‑Stack Engineer, you will be a core contributor shaping both the React/TypeScript frontend and the ASP.NET backend, delivering end-to-end features from UI through API and data persistence. This is a full-product ownership role in a HIPAA-regulated healthcare environment, requiring strong technical judgment, attention to compliance, and close collaboration with engineers and product stakeholders. You will work within a Human → AI → Human engineering workflow, using AI tools to accelerate development while maintaining full accountability for code quality, correctness, security, and compliance. Key Responsibilities Full‑Stack Delivery (End‑to‑End) - Design, build, and maintain customer-facing features across the full stack (React UI → ASP.NET APIs → MS SQL). - Collaborate with product stakeholders and engineers throughout feature definition, implementation, and release. - Participate in AI-augmented development workflows, reviewing and validating AI-generated code against acceptance criteria. - Follow Git best practices: feature branches, pull requests for all changes, and clear commit hygiene; proactively update documentation when behavior or architecture changes. Frontend (React/TypeScript) - Build and maintain React components and user workflows for a dental practice scheduling application (or similar clinical/operational workflows). - Implement clean, readable TypeScript that is maintainable and testable, with attention to UI correctness and edge cases. - Integrate frontend features with backend APIs, handling authentication, error states, loading states, and performance considerations. - Manage dependencies and build tooling via NPM (versioning, scripts, and reproducible builds). Backend (ASP.NET + MS SQL + Azure) - Design and implement RESTful APIs using ASP.NET to support frontend workflows and integrations. - Design and evolve MS SQL schemas with emphasis on clarity, performance, and data integrity. - Implement secure authentication/authorization patterns suitable for a regulated environment (e.g., token-based auth, role-based access). - Build integrations and platform capabilities using Azure Services (e.g., app hosting, identity, messaging, storage, monitoring as applicable). - Use Postman for API exploration, contract validation, test collections, and troubleshooting across environments. Quality, Testing, and Agile Execution - Demonstrate knowledge of QA processes in an Agile environment, including acceptance criteria, defect triage, regression awareness, and collaboration with QA roles. - Contribute to test strategy (unit/integration as appropriate), and ensure features meet functional, security, and reliability expectations. - Maintain a disciplined approach to compliance and secure engineering practices.
