Senior Full-Stack Engineer, Taktile

• 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
• Strong engineering fundamentals with a passion for simplicity and precision
• Fluency in English, both written and spoken, is essential as we operate in a remote environment requiring clear and effective communication. Strong English skills are also crucial to efficiently interacting with AI
• 5+ years of professional full-stack experience, including strong proficiency with React and TypeScript
• Professional experience building backend services in Python (FastAPI or equivalent), including REST APIs and databases
• Experience integrating into AWS or similar cloud providers
• A genuine interest in security and access control, with exposure to authentication and authorization concepts (RBAC, SSO, OAuth/OIDC, multi-tenant permissions)

Desirable

• 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
• 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 record of who accessed what, when, and why
• Design for regulated-industry constraints (financial services, SOC 2 / ISO 27001, data residency), where access control is a compliance requirement, not just a feature
• Leverage leading edge AI tools (e.g. Claude) on a daily basis to build industry-shaping AI-native capabilities
• Work across the full stack to build our IAM, authorization, and permissions systems: front-end in React/TypeScript and backend in Python (FastAPI), on an AWS serverless architecture
• Build and maintain these security-critical systems with care: review pull requests with depth and invest in strong test automation
• Engage actively in team rituals such as daily syncs, planning sessions, demos, and technical deep-dive discussions
• Grow as an individual and accelerate your career by learning from our experienced team, contributing to a foundational layer of the product, and joining cross-team learning groups
• From day one you'll contribute across both front-end and backend, taking on backend work early and deepening your ownership of our IAM and permissions systems over time
