- Contribute to cryptographic protocol implementation and security infrastructure.
Developer Experience

- Support customer integration efforts and address technical challenges.
- Collaborate with product and frontend teams to improve developer experience.

- Strong proficiency in at least one of: TypeScript, Rust, or Go.
- Strong experience with REST API design, with GraphQL experience a plus.

- Understanding of authentication protocols (OAuth2, OpenID Connect).
- Experience with browser automation tools (Playwright, Puppeteer) is a plus.
- Knowledge of networking protocols (HTTP, TCP, TLS) is a plus.
Culture and Mindset
- Builder mentality with examples of shipped products or significant features.
- Self-motivated problem-solver who can work with incomplete information.
- Excellent communication skills and ability to work cross-functionally.
- Strong desire to learn and adapt in a fast-paced environment.
- Commitment to code quality and engineering best practices.
Compensation & Benefits

- Comprehensive health, dental, and vision insurance.
- Company-provided workstation setup of your choice.
- Free gym membership at your preferred location.
- In-person work environment and team events in San Francisco (Hayes Valley).
In Conclusion
We're looking for builders who want to define the future of AI authentication. Our team includes former founders and early startup employees who have scaled products from 0 to 1. If you're excited about building critical infrastructure for the AI ecosystem and working with an exceptional team, we want to talk to you.
