About WorkOS 🚀

WorkOS builds modern developer tools and APIs that make it easy for companies to become Enterprise Ready. Our platform powers authentication, identity, authorization, and other critical infrastructure that developers need to securely scale their products to large organizations.

We recently raised a $100M Series C, valuing the company at $2B, led by Meritech and Sapphire with participation from Greenoaks, Craft, Abstract, and Audacious. WorkOS powers enterprise features for many of the fastest-growing AI companies, including OpenAI, Cursor, and Perplexity, Vercel, and Plaid.

As AI reshapes software, WorkOS is at the frontier of Human and Agent Authentication, Identity, and Access Control—helping companies answer a new critical question: who are your agents, and what are they allowed to do? Our fast-growing customer base includes hundreds of modern software companies building the next generation of enterprise-ready products.




About the role 💭

On this team, you will help build reliable, high-throughput systems, define new abstractions that make authorization requirements intuitive for developers, and design APIs that remain both scalable and simple. We are seeking engineers who are motivated by complex data modeling and distributed systems challenges, who take ownership of high-impact systems end to end, and who enjoy working directly with customers to deliver robust, production-ready products.

Responsibilities ✔️

- Architect and implement high-performance authorization systems that support real-time policy evaluation, scalable relationship modeling, and consistent permission enforcement across multi-tenant applications

- Build deep domain expertise in authorization paradigms such as RBAC, ABAC, ReBAC, hierarchical FGA, and policy-driven access control, along with best practices for domain modeling and permission boundaries

- Work closely with enterprise customers to understand their compliance, governance, and access control requirements, and translate those needs into product features such as delegated administration, advanced auditability, policy versioning, and conditional access

- Collaborate cross-functionally with other product teams, solutions engineering, and GTM to ensure Authorization integrates seamlessly with the broader WorkOS platform, including AuthKit, SSO, Directory Sync, Audit Logs and related developer workflows

- Explore new greenfield opportunities, including incremental authorization primitives, real-time change propagation, agent identity, policy workflows, richer SDK capabilities, and deeper ecosystem integrations

- Play an active role in recruiting, mentoring, and developing the engineering team that will build and refine the Authorization product roadmap
