About the project: Build the backend foundation for a modern multi-tenant SaaS platform transforming legal operations. Work with Node.js, TypeScript, PostgreSQL, and Azure to shape architecture, data isolation, permissions, integrations, audit systems, and AI-powered workflows from day one. Your expertise will directly influence the platform’s technical direction and the product used by legal teams every day.

A new team member will be in charge of: Owning the multi-tenant architecture, schema-per-tenant PostgreSQL, data-access layer, and automated tenant isolation guarantees. Building configurable object-, record-, and field-level permissions across lists, search, reports, exports, notifications, and AI features. Implementing ethical walls and tamper-evident, append-only auditing with field-level change history. Integrating Microsoft Entra ID via OIDC for internal users and SAML for external users. Integrating Azure OpenAI through the backend, ensuring AI features respect the calling user’s permissions. Defining backend architecture, code quality, and security standards.

Does this relate to you? 5+ years of hands-on Node.js and TypeScript experience, including building and operating production backends. Experience with multi-tenant SaaS using schema-per-tenant PostgreSQL or a comparable strong-isolation architecture. Strong PostgreSQL skills in data modeling, performance tuning, and migrations at scale. Experience with RBAC, record- and field-level permissions, OIDC, SAML, and SSO integrations. Hands-on cloud-native development on Azure using Container Apps or App Service. An approach that treats access control and data isolation as core requirements from the start. Daily use of Claude Code, Cursor, Codex, or similar tools to delegate implementation, with engineering oversight, review, testing, and validation. English B2+
