Description Defining how AI and finance work together — securely, intelligently, and at scale. We at Unique AI are building a highly secure generative AI platform, tailored for the financial sector. Utilizing AI, LLM, agentic and Skills technologies, we aim to revolutionize the Financial industry with an AI Automated workforce. Our mission is to increase efficiency, improve alpha, reduce risk, and increase quality across everything we do. We offer an inclusive environment at Unique and we encourage all genders and all neuro-diversities to apply. We're building an enterprise AI platform where secure access and user lifecycle management are core product capabilities. Every workspace, assistant, admin surface, and API depends on the platform correctly handling who a user is, what they can access, how roles are assigned, and how identity changes propagate across the system. We're looking for a senior backend engineer to work on the services behind authorization and user management. This role sits at the intersection of product functionality, platform reliability, and enterprise security. Requirements 5 years of backend engineering experience with strong expertise in TypeScript, Node.js, and structured backend frameworks such as NestJS Strong domain experience in authorization, identity, or user management systems in production SaaS environments Excellent system design skills : you can model roles, permissions, policy propagation, and service boundaries in a way that stays understandable as the platform grows Experience with enterprise identity concepts such as SSO, RBAC, provisioning, deprovisioning, webhooks, SCIM, or IdP integrations Multi-tenant SaaS experience with strong awareness of tenant isolation, auditability, and security-sensitive change management Event-driven systems experience : comfortable with asynchronous workflows, retries, idempotency, and eventual consistency in backend services Testing discipline : you write tests for critical business and security logic, not just happy paths
