The role

Raydar is recruiting for this role on behalf of our client. Lead the applied AI work for a software product, covering model integration, data flows, quality measurement and release.

\- Act as the go-to colleague for model-related issues across the team.

## Requirements

What we're looking for

\- Prior delivery of an AI or ML feature that real users depended on in production, beyond prototypes or internal demos.

\- Background at an organization known for a demanding engineering standard.

\- Experience at a growth-stage startup, ideally one with venture investors.

Bonus points
