What the job involves
- Proton is looking for a Senior Data Engineer to help us scale our Client Engineering

- You'll be responsible for designing, building, and owning robust data pipelines that deliver real value to our customers
- You’ll partner closely with client stakeholders and internal teams to deliver reliable, performant integrations and continuously improve the integration platform that powers them
- This role is perfect for a senior data engineer who thrives in fast-paced environments, values customer impact, and wants to shape the systems they operate in
- You'll help us grow our integration platform from handling 500+ Airflow jobs and 100GB of data ingested daily to 1TB+ and thousands of jobs as our business scales

- Data Warehousing & Analytics: Build and customize reports for clients, using Looker and backed by our data warehouse. Extend Looker dashboards to meet evolving needs, and improve the underlying data models to ensure accuracy, clarity, and performance
- Cross-Functional Collaboration: Work closely with Customer Success, Product, and Engineering teams to prioritize work, debug issues, and deliver exceptional client outcomes
Our take
Proton.ai is part of a new wave of companies rethinking how sales teams operate in an increasingly digital-first world. Rather than simply digitizing existing workflows, it uses automation and AI to reduce manual effort and guide decision-making, so sales reps can focus on the right customers, products, and moments to engage.
The sales automation market is booming, but also crowded, forcing companies to specialize and stand out. Proton.ai has done exactly that by focusing on wholesale distributors, an often overlooked segment with complex inventories, fragmented systems, and highly relationship-driven sales processes. Its tools are designed to help both reps and customers navigate large product catalogues across multiple channels, bringing a layer of intelligence to what has traditionally been a manual, operationally heavy space.
That focus is now evolving into a broader platform play, with the company recently announcing an AI-powered "industry cloud" for distributors, combining CRM, product information management, eCommerce recommendations, and order automation into a single system. By replacing disconnected point solutions with a unified data layer, the company is positioning itself less as a tool and more as a core infrastructure for wholesale sales. Backed by strong funding and growing adoption, this shift gives Proton.ai a clear path to scale.
