ML Ops Engineer

Nift is disrupting performance marketing, delivering millions of new customers to brands every month. We're looking for a hands-on ML Ops Engineer to partner with our data scientists to turn their models into production-ready systems.
In this role, you'll report to the Data Science Manager and work closely with our Data Scientists and Product developers. You'll architect storage and compute, harden training/inference pipelines, and make our ML code, data workflows, and services reliable, reproducible, observable, and cost-efficient. You'll also set best practices and help scale our platform as Nift grows.
Our Mission:
Nift's mission is to reshape how people discover and try new brands by introducing them to new products and services through thoughtful "thank-you" gifts. Our customer-first approach ensures businesses acquire new customers efficiently while making customers feel valued and rewarded. We are a data-driven, cash-flow-positive company that has experienced 731% growth over the last three years. Now, we're scaling to become one of the largest sources for new customer acquisition worldwide.
Backed by Spark Capital & Foundry who also invested in Slack, Snap, SeatGeek, Fitbit, Warby Parker, Wayfair and Twitter, we are poised for exponential growth and ready to demonstrate impact on a global scale. Read more about our growth here.
