Job Summary

Job Technologies
Your role in the team
- 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.
- 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).
- 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 back-end, taking on back-end work early and deepening your ownership of our IAM and permissions systems over time.

Our expectations of you
Qualifications
- 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.
- A genuine interest in security and access control, with exposure to authentication and authorization concepts (RBAC, SSO, OAuth/OIDC, multi-tenant permissions).
- Deeper backend specialization (async patterns, performance tuning, data modeling) is nice to have.
- DynamoDB or Postgres, SQLAlchemy is nice to have.
Experience
- 3+ 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.
- Hands-on experience designing authorization systems at scale: fine-grained / ReBAC models, policy engines (OpenFGA or Zanzibar-style systems, OPA), or multi-tenant RBAC for enterprise SaaS is nice to have.
- Prior ops or on-call experience is nice to have.
