Fullstack Developer (Frontend Focus - TypeScript/React)

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.

Core Technical Skills

• Strong experience with modern frontend frameworks (React, Angular, Vue, or similar) andTypeScrip , including building maintainable components and application flows.
• Strong experience building backend services with ASP.NET and designing/consuming REST APIs.
• Solid relational database skills with MS SQL (schema design, query awareness, performance basics).
• Practical experience using Postman for API validation and troubleshooting.
• Hands-on experience working with Azure Services in a product engineering context.
• Familiarity with Git-based workflows (pull requests, code reviews) and maintaining engineering documentation.
  

AI‑Augmented Development (Required)

• Hands-on experience using AI coding assistants as part of daily development, with a clear understanding of the Human → AI → Human review loop and human accountability.
• Ability to maintain supporting documentation such as READMEs, architecture notes, and engineering guidelines.
  

HIPAA & Compliance Awareness (Required)

• Strong understanding that Protected Health Information (PHI) must never appear in code, logs, tests, commits, or error messages; comfort working with synthetic/mock data.
• Awareness of secure coding practices (no hardcoded credentials, least-privilege access patterns, safe error handling).
  

Technologies & Tools

Frontend

Ways of Working

• Agile QA process awareness (definition of done, acceptance criteria validation, test collaboration, release readiness)
• AI-assisted engineering with human ownership of outcomes
  

Preferred / Nice‑to‑Have Qualifications

• Healthcare or dental domain experience.
• Experience contributing to a greenfield product from early stages.
• Experience building interactive or dynamic UI features (e.g., data visualization, image manipulation, or real-time interfaces).
• Familiarity with authentication flows and securing SPAs/APIs in enterprise environments.

How We Work

• AI-assisted engineering: AI tools are used for acceleration, but all code is reviewed and owned by engineers.
• Branch-based development: Work is done on feature branches with pull requests and code reviews.
• Quality & compliance mindset: Engineering practices include security awareness and careful handling of regulated data.

• Work remotely Monday - Friday, 40 hours a week (no weekends)
• Health Care Reimbursement
• Active Lifestyle Reimbursement
• Quarterly Home Office Reimbursement
• Did we mention it's REMOTE?!!
