Junior Software Engineer
Fospha is the measurement system enterprise retail and ecommerce brands run their business on.

It replaces guesswork and gut feel with a number marketing, finance and agencies can all trust and act on.

We've spent over a decade building this, with more than $40 billion in marketing spend now optimised through the platform — and we're scaling fast across London, Mumbai and Austin.
