About Passionfruit

Passionfruit is reshaping how marketing teams work. We started as a marketplace connecting brands with specialist marketers, and we're now building PIP, an AI-native platform that's changing how marketing operations actually get done.

We're not building generic AI tools and hoping marketers find them useful. We're building with marketing teams, because that's the only way to make something that genuinely works. Every feature, workflow, and integration comes from real problems we've seen up close.

About PIP

PIP is our AI-native workspace for modern marketing operations. It centralises context, insights, and workflows into one intelligent platform - helping teams analyse performance, automate reporting, and extract meaningful answers from their data in minutes rather than days.

We ship fast, iterate based on real feedback, and scale deliberately. Quality is critical to everything we build – especially as we introduce AI‑driven features and complex data workflows into core marketing operations.

The Role

We're looking for a QA Engineer to join our team and ensure PIP delivers reliable, high‑quality experiences at scale.

You’ll work across product, engineering, and AI to test core features, validate data pipelines, and improve confidence in both traditional software and AI‑generated outputs. You’ll play a key role in shaping how quality is defined and maintained as we move fast and build from first principles.
