About the role
Identity is the front door to every system an employee or contractor touches, and this role owns it. You design and build the platform that decides who gets access to what, and you write the code that runs it. You own the technical direction for identity and build alongside peer specialists covering the rest of the enterprise security surface. Application Tip: Interested in sharing your technical work? You are welcome to add your GitHub profile or links to projects you've built in the 'Websites' section. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Own passwordless authentication (e.g. passkeys) for the workforce, across employee and contractor identities
- Define enrollment rules for which authentication methods are required, optional, or disallowed by population, setting the assurance bar before a user ever reaches session or app-level policy
- Design authenticator assurance tiers and tune session policy: session lifetime, idle timeout, and step-up re-authentication scaled to the risk of what's being accessed
- Own the non-human identity inventory: service accounts, API keys, and workload identities, each tracked, owned, and issued short-lived, federated credentials with automatic expiry
- Treat AI agents as their own identity class: scoped, single-use credentials per action, clear delegation from the human or system they act for, and an audit trail granular enough to attribute every individual action
- Manage identity configuration as code, shipping and reviewing every change through pull requests, so a bad policy change is as easy to revert as it was to ship
