Staff Full Stack Engineer, Post Order Experience

About CookUnity: Food has lost its soul to modern convenience. And with it, it has lost the power to nourish, inspire, and connect us. So in 2018, CookUnity was founded as the first-of-its-kind platform that connects the world with the source of truly great food: chefs. Today, CookUnity delivers 50 million meals a year from the industry’s best chefs to homes all over the country. Fresh. Ready-to-eat. And crafted with the passion that nourishes body and soul. Unwilling to stop there, CookUnity is expanding beyond delivery to become an ever-innovating marketplace focused on our singular mission: empower Chefs to nourish the world. If that mission has you hungry in more ways than one, you’ve found the right job posting. About CookUnity Food has lost its soul to modern convenience.

About the Team: The Post Order Experience team owns what happens after a customer places an order, the moments that determine whether CookUnity feels dependable, flexible, and easy to fit into everyday life. We build the experiences that help customers stay in control when plans change, whether they need to manage or reschedule an order, skip a delivery, pause their subscription, or cancel when CookUnity no longer meets their needs. We also look for thoughtful ways to understand and address why someone may want to leave, while always making the experience clear, respectful, and easy to navigate. This is a broad, high-impact space where simple customer experiences often sit on top of significant operational complexity. We partner closely with Engineering, Design, Data, Customer Experience, and Operations to turn that complexity into journeys that feel intuitive and trustworthy. Our work directly shapes customer satisfaction and retention and, most importantly, whether customers feel confident and cared for long after checkout.

A quick note for all candidates We’ve recently seen an increase in recruitment scams across the industry, and we want to make sure you (and your data) stay safe while applying to CookUnity. We also want you to know that we take this seriously — sometimes, as part of our process, we may ask for a brief “proof of humanity” to confirm that we’re connecting with a real person, not an impersonator. Here are a few tips to help you protect yourself and know what to expect from us: • Apply only through our official channels. All open roles are listed on our official careers page: careers.cookunity.com • Our recruiters are real people — and easy to verify. You can always find them on LinkedIn with verified profiles. If you’re unsure, feel free to reach out to us on our official LinkedIn Company Page. • We only communicate through official CookUnity channels. That means emails ending in @cookunity.com and interviews held through official company platforms (Google Meet or Zoom) — never WhatsApp, Telegram, or SMS. • We’ll never ask for payment or personal financial details. If anyone does, please don’t share any information and let us know right away. If something ever feels off or you’re unsure about a message, we’d much rather you double-check with us. You can always contact us directly through any of our social media channels. We appreciate your interest in joining CookUnity — and we care about keeping your experience (and safety) as genuine as possible.
