Senior Full-Stack Web Developer (Contract) - AI Analytics Web Application
Location: Remote (US), with working hours overlapping US Central time
Type: Contract, 6 months, with possible extension
About the role
We have a working AI analytics product, used today by a group of enterprise clients, that lets claims professionals ask questions about their own claims data in plain English and get answers with tables, charts and verified figures. It currently runs inside a notebook platform. We're moving it to a standalone, multi-tenant web application embedded in our client portal, hosted on Azure, with the analytics engine packaged as a Python service.
You'll build the web application: the backend API around our Python analytics engine, the conversational front end, secure multi-client access, and the deployment pipeline. You'll work with our data engineers, who own the Snowflake data platform and the engine package, and with the product owner, who signs off each release.
What you'll build
Backend API (Python): REST endpoints for conversations, follow-up questions, reset, dashboards and reports, claim drill-downs, CSV exports and feedback, wrapping our existing analytics engine package. No client identifier is ever passed in a request; the tenant comes from the authenticated session.
Conversational front end: a chat-style interface with streaming or progressive responses, data tables (sorting, paging, large exports), charts, "how this was calculated" notes, clear verified / unverified answer labels, clarifying-question flows, and feedback capture.
Portal embedding and authentication: integrate with our client portal's session (SSO / token handoff), derive the user's entitled client(s), support users with access to more than one client, and embed securely.
Multi-tenant security: per-request tenant context enforced in the application and backed by database-level row security; per-client Snowflake service identities (key-pair authentication, secrets in Azure Key Vault); automated per-tenant isolation tests in every release.
Data access: Snowflake connectivity (parameterized queries, connection pooling per tenant), Snowflake Cortex APIs (Cortex Agent and Cortex Analyst REST endpoints), and safe handling of long-running analytical queries.
Storage and logging: conversation history, usage and answer logging (insert-only, tenant-scoped), and feedback.
Azure hosting and DevOps: containerized deployment (e.g. Azure App Service or Container Apps), Key Vault, environment configuration, CI/CD in Azure DevOps, staged environments, and release gates that run our automated test suites.
Quality and operations: automated tests (unit, API, end-to-end), monitoring and alerting, structured logging, performance for answers that can take 30-120 seconds, accessibility (WCAG 2.1 AA), and security reviews (OWASP Top 10).
