Senior Full-Stack Engineer - Platform team

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.

Frontend: React, TypeScript

Backend: Python (FastAPI)

Cloud: AWS serverless

Security: authN/authZ, SSO/OAuth/OIDC, fine-grained permissions (RBAC/ReBAC)

Deeper backend specialization (async patterns, performance tuning, data modeling).

DynamoDB or Postgres, SQLAlchemy.

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.

Prior ops or on-call experience.
