Senior Fullstack Engineer

About the role Cloudbox is building a unified multi-tenant data and reporting platform serving hedge fund and financial-services clients. You'll own the client-facing and internal application layer: React dashboards, the REST API, authentication, and the security boundary between tenants. What you'll own - Two-level multi-tenant isolation (tenant and end-client) - enforced across API, storage, and network layers, tested as a CI isolation gate that blocks deployment - React-based dashboard applications (client-facing and internal operations views) - RESTful API design and implementation (Azure Functions) - versioned, serving read-only queries over the gold layer - Entra ID SSO integration and access control - The full reporting engine - lakehouse snapshot, PDF generation, schedule configuration, email delivery, and the client portal archive - Cross-cutting controls on the application layer - immutable (WORM) audit logging on write paths, structured logs, SLOs, and alerting What we're looking for - Senior-level experience shipping production React applications - Strong API design skills; comfortable owning a service end-to-end - Hands-on across the Azure platform - Function Apps, Static Web Apps, Blob Storage, Key Vault, and monitoring/observability with Application Insights - Managed identity and Key Vault-backed secret handling as default practice - no credentials in code - Source control and CI/CD experience with both Azure DevOps and GitHub, including PR-based workflows with preview deployments - Experience with SSO/OAuth-based authentication (Entra ID/Azure AD a strong plus) - Security-conscious engineering practice - this platform serves regulated financial-services clients and multi-tenant data isolation is non-negotiable. We will ask for evidence: multi-tenant isolation shipped in production, or a security review you can walk us through - Comfortable working closely with a Data & AI Engineer whose lakehouse output your API and dashboards consume
