About Ditto
At Ditto, we're redefining digital trust. Our unified identity platform helps banks, financial institutions, governments and other regulated organisations verify identities, prevent fraud and deliver secure digital experiences through identity verification, authentication, passwordless access and mobile threat defence.
We're a general team with a startup mindset, led by CEO Gonzalo Alonso, on a mission to make digital trust simple, secure and accessible.
The Role
AI agents are beginning to act on behalf of people and businesses—making decisions, transacting, and connecting to other systems on their own. The identity tools most organisations rely on today were built for people or predictable machine identities, not autonomous agents.
Ditto is investing in an agentic identity platform to address this. We're hiring a Senior Principal Engineer to help design and build it—hands-on—drawing on Ditto's heritage in identity, device binding, runtime protection and continuous authentication,
and using large language models as a genuine force-multiplier for the research and the delivery.
In one line: own the design and hands-on build of the platform's hardest capabilities—verifiable agent identity, instance integrity, and continuous runtime trust—on a modern, standards-based foundation, moving at real pace.

Grow and mentor the team that scales the platform—a genuine principal-level remit.
Engage the broader standards and security community to keep the work current, credible and interoperable.
What You'll Work With
