Proton is building the AI operating system for wholesale distribution, embedded in the workflows that move nearly every physical product on the planet. Distribution is a $9 trillion industry, and the software that runs it has been stuck in the past for decades — most tools create more work than they eliminate. We unify CRM, PIM, eCommerce AI, and Order & Quote Entry AI into one platform with one data layer and one AI brain, so reps spend their time deepening customer relationships, not entering data.
At Proton, everyone is a builder who owns problems end to end and ships AI-native software faster than anyone else in the category.
The median Proton customer reports 3x profit return per dollar spent, an extra day of sales per rep per month, and "the best ROI of any tech investment in 30 years." Hundreds of leading distributors — from family-owned shops to publicly-traded enterprises across, industrial, HVAC, electrical — run on Proton. We're backed by Felicis Ventures (Twitch, Shopify, Opendoor) and Battery Ventures.




If you want to build the systems that shape how trillions of dollars of physical goods move through the economy, Proton is the place to do it.
We're hiring a Senior Data Engineer to own and grow our Data Layer — the unified foundation that every Proton product and our AI brain are built on. We're investing heavily to make the Data Layer bigger and better, and this role is for someone who wants to do the hands‐on building and shape where it goes next.
Two things make this role different from a standard data engineering opening:
When the AI gives a wrong answer or a number doesn't match the source, the trail leads back to the data. You own correctness end to end — ingestion, modeling, reconciliation, and the contracts other teams depend on.
Location: Europe, remote. Own the Data Layer end to end: ingestion from file-, event-, and API-based sources; Build and operate the ingestion and transformation pipelines that power the Data Layer
