Product Engineer
Pubblicato il 17-08-2026 - Cassandra in Roma
Cassandra is the first self-service platform for Marketing Mix Modeling: model the effectiveness of your media mix and get media plans that maximize your sales — without a data science team.
Measuring marketing effectiveness used to mean six-figure consulting contracts and months of waiting. The econometrics behind it — the kind of work Nielsen built an empire on — was reserved for companies that could afford it. We took that niche technology and made it accessible to non-technical marketers, in days instead of months, at a fraction of the price.
Today we analyze over €500M in ad spend for 100+ brands worldwide, including Velasca, Boscolo and Takomo, and we're a team of ~20 across Rome and Milan.
We're backed by a €2M seed round led by Italian Founders Fund, with PitchDrive, Webranking and Mana Ventures
We're looking for a Product Engineer — and we mean it literally. You won't receive specs to implement. You'll own problems: talk to marketers, decide what to build, ship it, measure whether it worked. Our product cycles are collapsing from months to weeks,
and this role is how we get there.
Tasks
- Own product problems end-to-end — from framing them with real marketers, through design and implementation, to measuring adoption after release
- Ship user-facing features across the stack: React frontend, Django backend, on AWS
- Turn complex econometric output into interfaces a CMO can act on in five minutes
- Contribute to the ongoing redesign of the platform, challenging what's already there rather than porting it over
- Use AI tooling aggressively to compress the distance between idea and production
- Work directly with our customers. You'll see the spreadsheets they're escaping from, and you'll know within days whether what you shipped helped
You'll own a product metric: activation — the share of new clients who reach their first actionable model and come back to it. Not a ticket you close, a number you report on and defend. It's what drives our retention, and it's
