About the role

Key responsibilities & impact

Help build the foundation for secure access at Owner — design and improve the authentication and authorization systems that power every product surface across the platform.
Own critical auth infrastructure end to end — contribute to systems for login, sessions, token management, service-to-service auth, account security, and access enforcement.
Improve reliability and observability — instrument auth services with the alerting, dashboards, and runbooks needed to detect issues quickly and keep critical access flows healthy.
Raise the security bar — identify risks, improve controls, and help ensure authentication and authorization are designed thoughtfully from the beginning, not added as an afterthought.
Leverage AI tools to move faster — use AI tooling to accelerate your work, from writing and reviewing code to exploring solutions and automating repetitive tasks.
Help us build a great team — interview candidates, share technical context, and raise the bar for how we build.
