Food Scientist

A Little About Us

We are not accepting candidates from third-party recruiters or agencies for this role — direct applicants only.

Oats Overnight is on a mission to build a generational CPG brand. Since 2016, our high-protein, drinkable oatmeal has reached over a million customers through direct-to-consumer, and we’re now scaling with all major nationwide retail and club partners. Our goal: become a household brand by leveraging speed, storytelling, and strategy.

We are vertically integrated: we develop, manufacture, and fulfill everything in-house. This operational control allows us to engage customers directly into the R&D process, an initiative where we were first-to-market in CPG. It also makes our brand tangible and real: our factory, our team, and our product pipeline are all part of the narrative.

This is an exciting stage - we are emerging as a significant omni-channel brand and launching new products to capture significant market share across verticals. We want you to help us get there.

Every teammate here has equity because we’re building something big, and everyone plays an important role. If you’re excited about building a brand that does things differently, this is that opportunity.

We are seeking a Food Scientist with a passion for new ingredient qualification, current ingredient optimization, and new product innovation.
