About the role

Key responsibilities & impact

Design, build, and maintain a Rails API (API-only mode) that serves dental scheduling data to a React frontend
Model and evolve PostgreSQL schemas using ActiveRecord migrations, targeting Azure PostgreSQL Hyperscale (Citus) in production with an emphasis on clarity, performance, and data integrity
Become the team’s subject matter expert on data mapping across different dental practice management systems and the Cosmos DB data layer
Query and consume data from Azure Cosmos DB, understanding its document model and how DPMS data is structured within it
Design and maintain application schemas on Azure PostgreSQL Hyperscale (Citus), leveraging distributed tables and colocation for performance at scale
Integrate with external healthcare systems and services via HTTP — including dental exchange APIs, payment processors, and Azure AI services — to power features such as AI-assisted dictation and intelligent workflows
Implement and maintain Azure AD B2C JWT authentication middleware, including JWKS retrieval, signature verification, claim extraction, and current_user injection
Build and operate background jobs using Sidekiq and Redis for asynchronous and long-running tasks
Write and maintain comprehensive RSpec test suites using FactoryBot, WebMock, and VCR to safely test external HTTP integrations
Run and remediate findings from Brakeman and bundler-audit as part of normal development workflows
Contribute to React frontend components and pages as needed
Collaborate closely with frontend-focused engineers and product stakeholders throughout feature development
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 conventional commit messages
Proactively update documentation when behavior or architecture changes

Requirements

What you’ll need

Strong experience with Ruby on Rails in API-only mode, including ActiveRecord, migrations, routing, and middleware
Solid PostgreSQL knowledge, including schema design and query awareness; comfort working with both relational and NoSQL (document) databases
Experience designing REST APIs and integrating with external services via HTTP clients (e.g., Typhoeus, Faraday, or equivalent)
Hands-on experience with background job processing (Sidekiq or equivalent)
Experience implementing JWT-based authentication, including JWKS validation and claim extraction
Proven RSpec testing discipline with FactoryBot and HTTP stubbing using WebMock or VCR
Working knowledge of a modern frontend framework (React, Vue, or similar) — you don’t need to be a CSS wizard, but you should be comfortable building and debugging components
Familiarity with Git-based workflows, pull requests, and conventional commits
Comfortable reading and maintaining Markdown documentation
Hands-on experience using AI coding assistants (e.g., Claude Code, GitHub Copilot, Cursor) as part of daily development
Clear understanding of the Human → AI → Human review loop, with human ownership of all decisions
Strong understanding that Protected Health Information (PHI) must never appear in code, tests, logs, commits, or error messages
Discipline around structured logging with explicit safe-field selection
Use of generic error messages with no patient-identifying context returned to API clients
Comfort working exclusively with synthetic or mock data
Awareness of secure coding practices, including no hardcoded credentials, OWASP Top 10 vigilance, and blocking remediation of Brakeman findings
