Senior Full-Stack Engineer - Platform team
About the role
Taktile helps financial institutions make smarter, safer decisions with the power of AI.. Our Engineering and Product Design teams are building multiple verticals on our platform at high speed, leveraging AI and building agentic functionality into the platform itself. As we scale into the world's largest regulated financial institutions, identity and access management (IAM), authorization, and fine-grained permissions have become foundational to our enterprise readiness.
We are hiring a Full-Stack Engineer to join the team building Taktile's IAM and permissions platform: the authorization backbone that powers enterprise-grade access control across our product.
This is a genuinely full-stack role: you'll design and build permission models and access controls end-to-end, from the React/TypeScript access-management and admin UIs down to the Python (FastAPI) authorization services. You'll take on the problems that make enterprise authorization genuinely hard: multi-tenant isolation, fine-grained permission checks in the hot path of millions of decisions a day, audit and access trails, and the constraints of regulated financial services.
Backend development is a core requirement, and you'll own features end-to-end (front-end, backend, and operations over time).
If you worked with Auth systems, Identity providers and complex authorization schemes we'd love to talk.
What You'll Do
- Design, build, and operate core authorization primitives such as roles, policies, and fine-grained permission checks (RBAC/ReBAC), along with the authentication and SSO/OAuth/OIDC flows that sit on top of them.
- Guarantee strict multi-tenant isolation so every customer's data and decisions stay fully segregated.
- Keep fine-grained permission checks fast in the hot path of millions of automated decisions per day, where both latency and correctness are non-negotiable.
- Build audit and access-trail capabilities that give customers and auditors a verifiable reco...
