Forward Deployed Engineer, UK in London

About Persona

Persona is the configurable identity platform built for businesses in a digital-first world.

Verifying individuals and organizations is harder — but more important — than ever, with AI enabling fraudsters to launch sophisticated accounts at scale and regulations evolving rapidly.

We’ve built Persona to support practically every use case and industry — that’s why we’re able to serve a wide range of leading companies.

For example, Reddit relies on Persona for age assurance and verification to comply with online safety regulations, protecting younger users while maintaining a seamless experience.

Meanwhile, Open AI relies on Persona to keep bad actors out, protecting one of the world’s most powerful AI platforms from large-scale abuse in a time when AI is reshaping the way we work and live.

We’re growing rapidly and looking for exceptional people to join us!

About the Role

As Persona’s first Forward Deployed Engineer in the UK, you’ll help customers turn complex identity challenges into practical solutions.

You’ll partner with our Solutions Engineering, Sales and Customer Success teams across the customer journey - from technical discovery and proofs of concept to building integrations and launching solutions.

This is an opportunity for someone with a strong technical foundation who enjoys building software, solving problems and working directly with customers.

You don’t need prior expertise in identity verification, but you should be comfortable writing code, navigating APIs and owning technical projects.

You’ll develop a deep understanding of our platform through hands‑on work and close collaboration with customers and teammates.

As part of our growing UK presence, you’ll also help shape how we share knowledge, deliver customer solutions and onboard future teammates.
